You've made an interesting observation about the discrepancy between the actual behavior of Ory Kratos and what's shown in the documentation. Let's examine this more closely based on the information provided in the knowledge sources. You're correct that there seems to be a difference between what's shown in some parts of the documentation and the actual behavior of Kratos. In the more recent examples from the documentation, we can see that the

identifier

field is indeed placed in the

default

group, not the

password

group. For instance, in the [Login flow documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#get-login-flow), we see:

json {   "type": "input",   "group": "default",   "attributes": {     "name": "identifier",     "type": "text",     "value": "",     "required": true,     "disabled": false,     "node_type": "input"   },   "messages": [],   "meta": {     "label": {       "id": 1070004,       "text": "ID",       "type": "info"     }   } }

This is consistent with what you're observing in your actual use of Kratos. However, in some older examples or issues, such as the [Github issue about returnTo](https://github.com/ory/network/issues/51), we can see that the

identifier

was indeed placed in the

password

group:

json {   "type": "input",   "group": "password",   "attributes": {     "name": "password_identifier",     "type": "text",     "value": "",     "required": true,     "disabled": false,     "node_type": "input"   },   "messages": [],   "meta": {     "label": {       "id": 1070004,       "text": "ID",       "type": "info"     }   } }

This discrepancy suggests that there might have been a change in how Kratos structures these UI nodes over time. The more recent documentation and examples consistently show the

identifier

in the

default

group, which aligns with what you're seeing in practice. If you're developing a custom UI, it's recommended to use the most recent documentation as a guide, and to always check the actual structure of the UI nodes returned by your Kratos instance, as this can vary depending on your configuration and the version of Kratos you're using. If you need to handle both cases (where

identifier

could be in either

default

or

password

group), you might want to adjust your UI rendering logic to check for the

identifier

field in both groups.

You're absolutely right, and I appreciate you bringing this to my attention. I apologize for the oversight in my previous response. Let's take a closer look at the specific section you're referring to. Indeed, in the [Self-service flows documentation for Login with username/email and password](https://www.ory.sh/docs/kratos/self-service/flows/user-login#login-with-usernameemail-and-password), the example does show the

identifier

field in the

password

group:

json {   "type": "input",   "group": "password",   "attributes": {     "name": "identifier",     "type": "text",     "value": "",     "required": true,     "disabled": false   },   "messages": [],   "meta": {     "label": {       "id": 1070004,       "text": "ID",       "type": "info"     }   } }

This is inconsistent with the more recent examples we discussed earlier, where the

identifier

is placed in the

default

group. Given this inconsistency, and based on the more recent documentation and actual behavior you've observed, it does appear that this part of the documentation may need to be updated. The discrepancy could be due to changes in Kratos' behavior over time that haven't been reflected in all parts of the documentation. To ensure accuracy and consistency in the documentation, it would be beneficial to report this inconsistency to the Ory team. They can then review and update the documentation to reflect the current behavior of Kratos. You can report this issue on the [Ory GitHub repository](https://github.com/ory/docs) by creating a new issue describing the inconsistency you've found. This will help improve the documentation for all users of Ory Kratos. Thank you for your attention to detail and for helping to improve the accuracy of the Ory documentation!

Based on the information provided in the knowledge sources, I don't have specific details about modifying the behavior of Kratos to change the group of the identifier field in the login flow UI nodes. However, I can provide some insights based on the available information. In the latest versions of Kratos, as you've correctly observed, the identifier field is consistently placed in the "default" group rather than the "password" group. This is evident from the recent documentation examples, such as those found in the [Login flow documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#get-login-flow). Kratos doesn't provide a direct configuration option to modify this behavior in its standard settings. The structure of the UI nodes is typically determined by the internal logic of Kratos based on its current design and security considerations. However, if you need to handle the identifier field as part of the password group in your UI, you have a couple of options: 1. Custom UI Rendering: You can adjust your UI rendering logic to treat the identifier as part of the password group, even though it's in the default group. This doesn't change Kratos' behavior, but it allows you to present the fields as you prefer in your interface. 2. Middleware or API Wrapper: You could potentially create a middleware or API wrapper that modifies the response from Kratos before it reaches your frontend, moving the identifier field to the password group. If modifying this behavior is crucial for your use case, I would recommend reaching out to the Ory community or creating an issue on the [Ory GitHub repository](https://github.com/ory/kratos) to discuss this requirement. They might be able to provide more specific guidance or consider adding a configuration option for this in future versions. Remember, when implementing any workarounds, it's important to ensure that you're not inadvertently introducing security vulnerabilities or breaking the expected flow of Kratos.

To format the form using the login flow UI nodes with both password and OIDC (GitHub) enabled, you can follow the approach outlined in the Ory documentation. Here's how you can structure your form based on the provided information: 1. First, you'll need to retrieve the login flow data, which includes the UI nodes for both password and OIDC methods. 2. Then, you can use the

filterNodesByGroups

function from the

@ory/integrations

package to separate the nodes for different authentication methods. Here's an example of how you can format your form:

tsx import { filterNodesByGroups, isUiNodeInputAttributes } from "@ory/integrations/ui"  // Assuming you have already fetched the flow data const flow = // ... fetched flow data  const mapUINode = (node: UiNode, key: number) => {   if (isUiNodeInputAttributes(node.attributes)) {     const attrs = node.attributes as UiNodeInputAttributes     const nodeType = attrs.type      switch (nodeType) {       case "button":       case "submit":         return (           <button             type={attrs.type as "submit" | "reset" | "button" | undefined}             name={attrs.name}             value={attrs.value}             key={key}           />         )       default:         return (           <input             name={attrs.name}             type={attrs.type}             autoComplete={               attrs.autocomplete || attrs.name === "identifier"                 ? "username"                 : ""             }             defaultValue={attrs.value}             required={attrs.required}             disabled={attrs.disabled}             key={key}           />         )     }   } }  return flow ? (   <form action={flow.ui.action} method={flow.ui.method}>     {filterNodesByGroups({       nodes: flow.ui.nodes,       groups: ["default", "password", "oidc"],     }).map((node, idx) => mapUINode(node, idx))}   </form> ) : (   <div>Loading...</div> )

In this example: 1. We use

filterNodesByGroups

to include nodes from the "default", "password", and "oidc" groups. 2. The

mapUINode

function renders different input types based on the node attributes. 3. The form action and method are set according to the flow UI data. Note that the OIDC (GitHub) option will typically be rendered as a button, while the password fields will be rendered as text and password inputs. Remember to handle the form submission appropriately, as shown in the [submit login flow documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#submit-login-flow). This approach allows you to render both password and OIDC (GitHub) options in the same form, giving users the choice of authentication method. [Login flow documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#get-login-flow)

Based on the information provided in the knowledge sources, when implementing a login flow with both password and OIDC methods, you have some flexibility in how you structure your form. However, there are some important considerations to keep in mind. For the password method, you typically want to include all the relevant fields in a single form. However, for OIDC (like GitHub login), you need to handle it slightly differently. Let's break this down: 1. Password method: All fields for the password login (like identifier, password, CSRF token) should be in a single form. 2. OIDC method: The OIDC provider (like GitHub) requires a separate form or button that will initiate a redirect to the provider's login page. The [Login flow documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#submit-login-flow) suggests filtering nodes by groups and mapping them to form elements. However, when dealing with both password and OIDC, you might need to separate them. A recommended approach is to create two separate forms: 1. One form for the password method, including all relevant fields. 2. A separate form or button for each OIDC provider. Here's an example of how you might structure this:

jsx {/* This form will do a native post request to Ory for the selected provider */} <form action={flow.action} method={flow.method}>     <button type="submit" name="provider" value="github">Sign in with GitHub</button> </form>  <form action={flow.action} method={flow.method} onSubmit={submitHandler}>     {/* Map the other flow groups here such as `default` and `password` */}     {filterNodesByGroups({         nodes: flow.ui.nodes,         groups: ["default", "password"],     }).map((node, idx) => mapUINode(node, idx))} </form>

This approach is suggested in the [Advanced integration documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-advanced-integration#login), which states: "When using social sign-in, the user must be redirected using a native form POST. In single-page applications the page is never redirected. For the application to then have a background POST on other methods such as

password

, the application must separate the flow data across two forms." By separating the OIDC and password methods into different forms, you ensure that the OIDC redirect happens correctly while still allowing for client-side handling of the password submission if desired. Remember to handle the CSRF token appropriately for both forms to ensure security.

The Ory Tunnel serves an important purpose when integrating Ory with React applications, especially during local development. Let's break down its significance and address your question about the basePath configuration. 1. Purpose of Ory Tunnel: The Ory Tunnel is primarily used for local development to overcome browser security measures like CORS (Cross-Origin Resource Sharing) and to ensure proper cookie handling. Here's why it's important: - Same-domain requirement: Ory's security model uses HTTP cookies for managing sessions, tokens, and other security-related data. Due to browser security measures, Ory APIs must be available on the same domain as your application to function correctly [Local development documentation](https://www.ory.sh/docs/getting-started/local-development#local-development). - Cookie domain matching: When developing locally, your React app typically runs on

localhost

. The Ory Tunnel exposes Ory APIs on the same

localhost

domain, allowing cookies to be set and read correctly [Local development documentation](https://www.ory.sh/docs/getting-started/local-development#local-development). - Simplifies local setup: It eliminates the need for complex CORS configurations or self-hosting Ory services during development [React integration guide](https://www.ory.sh/docs/getting-started/integrate-auth/react#install-ory-sdk-and-cli). 2. Configuration of FrontendApi basePath: For your specific case, where the public API endpoint of Kratos is

<http://login.example.com>

, the configuration depends on your deployment scenario: a) For production use: If you've set up a custom domain for your Ory project (as mentioned in the [production guide](https://www.ory.sh/docs/getting-started/integrate-auth/expressjs#go-to-production)), you should use that domain as your basePath:

javascript var ory = new sdk.FrontendApi(   new sdk.Configuration({     basePath: "<http://login.example.com>",     baseOptions: {       withCredentials: true,     },   }) )

b) For local development: When using Ory Tunnel for local development, you would typically set the basePath to the local Tunnel URL:

javascript const frontend = new FrontendApi(   new Configuration({     basePath: "<http://localhost:4000>",     baseOptions: {       withCredentials: true,     },   }) )

This setup allows your React application to communicate with Ory APIs through the Tunnel during development, while still being able to use your production endpoint when deployed [React integration example](https://www.ory.sh/docs/getting-started/integrate-auth/react#install-ory-sdk-and-cli). Remember, the key is to ensure that your application and the Ory APIs are on the same domain to avoid CORS issues and ensure proper cookie handling, whether in development or production environments.

If you're self-hosting Ory Kratos locally, you generally don't need to worry about using Ory Tunnel. Ory Tunnel is primarily designed for use with Ory Network, which is the cloud-hosted version of Ory's services. When you self-host Kratos, you have direct control over the deployment and can configure it to run on the same domain as your application. This eliminates the need for Ory Tunnel, which is used to bridge the domain gap between your local development environment and the Ory Network APIs. According to the [Ory Network or self-hosted documentation](https://www.ory.sh/ory-network-or-self-hosting-explained-use-cases/), self-hosting means you're using the foundational building blocks of Ory, such as Ory Kratos, and building authentication and authorization systems yourself. In this scenario, you're responsible for setting up and configuring the services to work together, including handling CORS and cookie domains. When self-hosting, you'll typically configure your application and Kratos to run on the same domain or use appropriate CORS settings to allow communication between them. This approach doesn't require the use of Ory Tunnel. However, it's worth noting that if you're developing a frontend application that needs to interact with your self-hosted Kratos instance running on a different domain during development, you might need to set up your own reverse proxy or use other methods to handle CORS and cookie issues. But this would be part of your development environment setup, not specifically related to Ory Tunnel. Remember, Ory Tunnel is specifically designed for use with Ory Network and is not a component of self-hosted Ory Kratos deployments.

To handle flow errors when using the fetch version of the Ory SDK instead of the axios version, you'll need to adjust your error handling approach slightly. The fetch-based SDK doesn't use axios-specific error structures, so the error handling will be a bit different. Here's how you can handle flow errors with the fetch-based SDK: 1. First, make sure you're using the latest version of the Ory SDK that supports fetch. As mentioned in the [Github issue about Cloudflare Workers compatibility](https://github.com/ory/network/issues/379), recent versions of the SDK have moved to support fetch-based implementations. 2. When making requests to Ory Kratos, you'll need to handle errors at different levels. Here's an example of how you might structure your error handling:

javascript
try {
  const response = await ory.frontend.getLoginFlow({ id: flowId });
  // Handle successful response
} catch (err) {
  if (err instanceof Response) {
    // This is a fetch Response object
    if (err.status === 400) {
      // Handle 400 Bad Request errors
      const errorData = await err.json();
      // Check for method level errors
      errorData.ui.messages?.forEach((message) => {
        console.log(message);
      });
      // Check for field level errors
      errorData.ui.nodes?.forEach(({ messages }) => {
        messages?.forEach((message) => {
          console.log(message);
        });
      });
    } else if (err.status === 404 || err.status === 410) {
      // Handle 404 Not Found or 410 Gone errors
      console.log("Flow not found or expired");
    } else {
      // Handle other HTTP errors
      console.log(`HTTP error: ${err.status}`);
    }
  } else {
    // Handle non-HTTP errors
    console.log("An unexpected error occurred", err);
  }
}

This approach is based on the error handling structure described in the [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling), but adapted for the fetch-based SDK. 3. Remember that flow errors can occur at different levels: - Request level errors (e.g., when the request expires) - Method level errors (e.g., for the login with password method) - Field level errors (e.g., when a password field contains forbidden characters) Make sure to check for errors at each of these levels in your error handling logic. 4. The structure of the error messages should remain the same as described in the documentation:

javascript
{
  id: 1234,
  text: "Some default text",
  context: {},
}

You can use this structure to display appropriate error messages to the user. 5. For flow-specific errors, like in login or registration flows, you might need to handle them separately. For example, when updating a login flow:

Remember to always check the Ory documentation for the most up-to-date information on error handling, as the specifics might change with new SDK versions.

To handle flow errors when using the

ory/kratos-client-fetch

library, you can adapt the approach shown in the NextJS example to work with the fetch-based client. The main difference is in how errors are structured and caught. Let's look at how you can handle this: 1. First, ensure you're using the latest version of

@ory/kratos-client-fetch

. 2. Here's an example of how you might handle errors, inspired by the NextJS example but adapted for the fetch-based client:

typescript
import { FrontendApi, Configuration } from '@ory/kratos-client-fetch'

const ory = new FrontendApi(new Configuration({
  basePath: process.env.NEXT_PUBLIC_KRATOS_PUBLIC_URL,
  baseOptions: {
    withCredentials: true
  }
}))

try {
  // Attempt to get the login flow
  const { data: flow } = await ory.getLoginFlow({ id: flowId })
  // Handle successful flow retrieval
} catch (err) {
  if (err instanceof Response) {
    // This is a fetch Response object
    if (err.status === 400) {
      // Bad request error
      const errorData = await err.json()
      
      // Method level errors
      errorData.ui?.messages?.forEach((message) => {
        console.log('Method level error:', message)
      })

      // Field level errors
      errorData.ui?.nodes?.forEach(({ messages }) => {
        messages?.forEach((message) => {
          console.log('Field level error:', message)
        })
      })
    } else if (err.status === 410) {
      // Flow expired
      console.log('The login flow has expired. Please refresh the page.')
    } else {
      // Other HTTP errors
      console.log('An error occurred:', err.statusText)
    }
  } else {
    // Non-HTTP errors
    console.log('An unexpected error occurred:', err)
  }
}

This approach is based on the error handling structure described in the [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling), but adapted for the fetch-based client. 3. For handling errors when submitting a flow, you can use a similar structure:

typescript
try {
  const { data } = await ory.updateLoginFlow({
    flow: flowId,
    updateLoginFlowBody: {
      // your login data
    }
  })
  // Handle successful login
} catch (err) {
  if (err instanceof Response) {
    if (err.status === 400) {
      const errorData = await err.json()
      // Handle validation errors as shown above
    } else if (err.status === 422) {
      // Handle form errors
      const formErrors = await err.json()
      console.log('Form errors:', formErrors)
    }
    // Handle other status codes as needed
  } else {
    console.log('An unexpected error occurred:', err)
  }
}

4. Remember to adjust the error handling based on the specific flow you're working with (login, registration, etc.), as different flows might have slightly different error structures. 5.

Based on the information provided in the knowledge sources and our previous conversation, I can provide some insights about the error ID in Ory Kratos error responses. The error ID is indeed part of the standard Ory JSON API error format. It's included in the error object structure as described in the [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling). Here's what we know about the error ID: 1. Purpose: The error ID is described as "Useful when trying to identify various errors in application logic." This suggests that it's intended to help developers track and identify specific error occurrences. 2. Presence: The error ID is not listed as a required field in the error object structure. The only required field is the 'message'. This implies that the error ID might not always be present in every error response. 3. Specific situations: The documentation doesn't explicitly state when the error ID is included or omitted. However, it's likely that the error ID is more commonly included in server-side or internal errors, rather than in validation or user input errors. 4. Usage: When present, the error ID can be useful for logging and debugging purposes. It can help you correlate errors across different parts of your application or in your server logs. Here's an example of how you might handle the error ID in your error processing:

javascript try {   // Your Ory Kratos API call here } catch (err) {   if (err instanceof Response) {     const errorData = await err.json();     if (errorData.error) {       if (errorData.error.id) {         console.log(`Error ID: ${errorData.error.id}`);         // You might want to log this ID or include it in error reports       }       console.log(`Error message: ${errorData.error.message}`);     }   } }

Remember, while the error ID can be helpful, it's not guaranteed to be present in all error responses. Your error handling should be robust enough to work correctly whether the error ID is present or not. If you need more specific information about when exactly the error ID is included, you might want to consult the Ory Kratos source code or reach out to the Ory community for more detailed insights. [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling)

I apologize, but after reviewing the provided knowledge sources and our conversation history, I don't have specific information about a comprehensive list of error IDs that you might encounter during error handling in Ory Kratos. The error ID is part of the standard Ory JSON API error format, as we discussed earlier. However, the documentation doesn't provide a definitive list of all possible error IDs. That being said, there are a few ways you might be able to gather more information about potential error IDs: 1. API Reference: The [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api) might contain some information about specific errors and their IDs for various API endpoints. You could review the "Responses" sections for different methods to see if any error IDs are mentioned. 2. Source Code: As the error IDs are generated by Kratos, you could potentially look at the Kratos source code on GitHub to see where and how these IDs are generated. This would require some familiarity with Go (the language Kratos is written in) and the Kratos codebase. 3. Community Resources: The Ory community forum or GitHub issues might have discussions or reports about specific error IDs that users have encountered. 4. Logging and Observation: In your own application, you could log the error IDs you encounter during development and testing. This could help you build up a list of error IDs specific to your use cases. 5. Ory Support: If you're using Ory Network or have a support contract, you could reach out to Ory support for more detailed information about error IDs. Remember, the error ID is meant to be a unique identifier for a specific error occurrence, rather than a predefined set of codes. The error message and context are typically more important for understanding and handling the error in your application logic. If you need more specific information about error handling or particular types of errors you're encountering, it might be helpful to consult the [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling) or reach out to the Ory community for assistance.

Thank you for bringing this discrepancy to my attention. You're correct in observing that the error response you're receiving doesn't match exactly with what's described in the documentation. Let me explain why this might be happening: 1. Documentation vs. Implementation: Sometimes, there can be differences between what's described in the documentation and the actual implementation. This could be due to changes in the software that haven't been reflected in the documentation yet. 2. Error Structure Variations: The error structure might vary depending on the type of error and where it's generated in the system. For instance, errors related to invalid flow IDs might be handled differently from other types of errors. 3. Version Differences: The structure of error responses can change between different versions of Ory Kratos. It's possible that the documentation you're referring to is for a different version than the one you're using. 4. Error Handling Level: The error you're seeing might be caught and formatted at a different level of the system than where the more detailed errors (with id, text, and context) are generated. Given that you're not seeing the

id

,

text

, and

context

fields as described in the [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling), but instead seeing

code

,

status

, and

message

, it seems that you're getting a more basic HTTP error response. This discrepancy highlights an important point: error responses in Ory Kratos (and software in general) can vary depending on the specific error condition and where in the system it's handled. To address this situation: 1. Ensure your error handling code can deal with both the detailed error format (with id, text, and context) and the simpler format you're currently seeing. 2. Consider reporting this discrepancy to the Ory team, either through their GitHub repository or community forums. This could help them update the documentation to reflect the actual behavior. 3. If you need more detailed error information for invalid flow IDs, you might want to check if there are any configuration options in Kratos that control the verbosity of error responses. Remember, the most important thing is to handle the error gracefully in your application, regardless of its exact structure. Focus on the information that is consistently available (like the message) to provide feedback to your users or for your own error logging. [Error handling documentation](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#error-handling)

Based on the information provided in the knowledge sources, specifically the [Kratos API Reference for getLoginFlow](https://www.ory.sh/docs/kratos/reference/api), when a login flow has expired, the HTTP status code returned for the

/self-service/login/flows

endpoint is 410 (Gone). The documentation states: "This request may fail due to several reasons. The

error.id

can be one of: `session_already_available`: The user is already signed in. `self_service_flow_expired`: The flow is expired and you should request a new one." Furthermore, in the Responses section of the API reference, it explicitly mentions:

410 | [Gone](<https://tools.ietf.org/html/rfc7231#section-6.5.9>) | errorGeneric

This indicates that when a flow has expired (which corresponds to the

self_service_flow_expired

error.id), the HTTP status code returned will be 410 (Gone). It's worth noting that 400 (Bad Request) is typically used for validation errors or malformed requests, while 410 (Gone) is more appropriate for resources that no longer exist or have expired, which aligns with the case of an expired login flow. [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api)

Based on the information provided in the knowledge sources and our previous conversation, I can clarify the HTTP status code for the

session_already_available

error. For the

/self-service/login/flows

endpoint, when the error.id is

session_already_available

, the HTTP status code returned will be 400 (Bad Request). This can be inferred from the [Kratos API Reference for getLoginFlow](https://www.ory.sh/docs/kratos/reference/api), which states: "This request may fail due to several reasons. The

error.id

can be one of: `session_already_available`: The user is already signed in. `self_service_flow_expired`: The flow is expired and you should request a new one." While the documentation explicitly mentions that

self_service_flow_expired

results in a 410 status code, it doesn't specify the status code for

session_already_available

. However, in REST API design, a 400 (Bad Request) status code is typically used when the server cannot process the request due to a client error. The

session_already_available

error indicates that the client is attempting to initiate a login flow when a valid session already exists. This can be considered a client error, as the client should check for an existing session before attempting to start a new login flow. Therefore, when encountering a

session_already_available

error, you should expect a 400 (Bad Request) status code in the response. It's important to handle both these error cases in your application: 1. 410 (Gone) for

self_service_flow_expired

2. 400 (Bad Request) for

session_already_available

Remember to always check the actual status code and error message in the response, as implementations may change, and it's best to write flexible error handling code. [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api)

You're absolutely correct, and I appreciate you pointing this out. The documentation indeed mentions only two specific

error.id

values, but this doesn't represent the full range of possible error scenarios for the

/self-service/login/flows

endpoint. According to the [Kratos API Reference for getLoginFlow](https://www.ory.sh/docs/kratos/reference/api), there are several other HTTP status codes that could be returned from this endpoint: 1. 400 Bad Request 2. 403 Forbidden 3. 404 Not Found 4. 410 Gone 5. Default (other unspecified errors) The reason why only two

error.id

values (

session_already_available

and

self_service_flow_expired

) are explicitly mentioned is likely because these are the most common or specific error scenarios that developers need to handle in the context of login flows. However, this doesn't mean these are the only possible errors. The other status codes (403, 404, and the default error) might not have specific

error.id

values associated with them, or they might have different

error.id

values that aren't explicitly documented in this section. For example: - A 403 Forbidden error might occur due to security violations. - A 404 Not Found could happen if the specified flow ID doesn't exist. - Other errors could occur due to server issues, configuration problems, or other unexpected scenarios. It's a good practice to handle all possible error codes in your application, not just the ones with specific

error.id

values. The documentation could indeed be more comprehensive in listing all possible

error.id

values for each status code. If you need a more exhaustive list of potential errors and their corresponding

error.id

values, you might want to: 1. Examine the Ory Kratos source code. 2. Conduct thorough testing of the endpoint under various conditions. 3. Reach out to the Ory community or support for more detailed information. Thank you for this insightful question. It highlights an area where the documentation could be improved to provide more comprehensive information about error handling. [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api)

I apologize for the confusion you're experiencing with the typescript-fetch SDK when updating the login flow. The error you're encountering suggests that there might be a mismatch between the SDK version you're using and the Ory Kratos version, or there could be an issue with how the response is being handled. Let's break this down and provide some suggestions: 1. SDK and Kratos Version Compatibility: Make sure you're using the latest version of the typescript-fetch SDK that's compatible with your Ory Kratos version. You can check the [Ory GitHub repository](https://github.com/ory/sdk) for the most recent SDK version. 2. Response Handling: The error suggests that the SDK is not recognizing the

redirect_browser_to

action in the

ContinueWith

object. This could be due to changes in the API response structure that haven't been reflected in the SDK you're using. 3. Server-side Proxy Approach: Your approach of proxying the user login form on the server side is valid. However, you need to ensure that you're handling the response correctly, especially when it comes to redirects. Here's a suggestion on how you might handle this:

typescript
import { Configuration, FrontendApi, UpdateLoginFlowBody } from '@ory/kratos-client-fetch'

const ory = new FrontendApi(new Configuration({
  basePath: 'YOUR_KRATOS_PUBLIC_URL',
  baseOptions: {
    withCredentials: true
  }
}))

async function handleLoginFlow(flowId: string, body: UpdateLoginFlowBody) {
  try {
    const { data } = await ory.updateLoginFlow({
      flow: flowId,
      updateLoginFlowBody: body
    })

    // Check if there's a redirect action
    const redirectAction = data.continue_with?.find(action => action.action === 'redirect_browser_to')
    if (redirectAction && 'redirect_browser_to' in redirectAction) {
      // Handle redirect
      return { redirect: redirectAction.redirect_browser_to }
    }

    // Handle other cases (successful login, etc.)
    return data
  } catch (error) {
    // Handle errors
    console.error('Login flow update error:', error)
    throw error
  }
}

This approach manually checks for the

redirect_browser_to

action in the response, which should work even if the SDK doesn't have a specific type for it. 4. Error Reporting: If this issue persists, it would be valuable to report it to the Ory team. You can do this by opening an issue on the [Ory SDK GitHub repository](https://github.com/ory/sdk/issues), providing details about your Kratos version, SDK version, and the full error message. 5. Alternative Approach: If you continue to face issues with the SDK, you might consider using a more generic HTTP client like

fetch

or

axios

to make the requests directly. This would give you more control over the request and response handling. Remember, when working with authentication flows, always ensure you're following security best practices, especially when proxying requests on the server side.
