The error message

"credentials.code.via has unknown value \"sms\""

indicates that Ory Kratos does not recognize

"sms"

as a valid value for the

via

field in your identity schema under

credentials.code

. However, according to the official Ory documentation and schema examples,

"sms"

is indeed the correct value for enabling SMS OTP for a phone number. Here’s a correct example from the docs:

Copy code

json "phone": {   "type": "string",   "format": "tel",   "title": "Phone number",   "<http://ory.sh/kratos|ory.sh/kratos>": {     "credentials": {       "code": {         "identifier": true,         "via": "sms"       }     }   } }

[Phone number and password schema example](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema#phone-number-and-password) Possible reasons for your error: 1. Schema Key Typo: In your schema, you wrote:

Copy code

"<http://ory.sh/kratos|ory.sh/kratos>":

It should be:

Copy code

"<http://ory.sh/kratos|ory.sh/kratos>":

The key must be exactly

"<http://ory.sh/kratos|ory.sh/kratos>"

(without angle brackets or pipes). 2. Ory Kratos Version: If you are using an older version of Ory Kratos, the

"sms"

value for

via

may not be supported. Make sure you are running a recent version that supports SMS OTP. 3. Configuration: Ensure that you have enabled the passwordless code strategy and configured the SMS channel correctly in your Ory configuration. See the docs for [enabling SMS OTP](https://www.ory.sh/docs/kratos/passwordless/one-time-code#enable-sms-one-time-code-otp). How to fix: - Update your schema to use the correct key:

Copy code

json   "phone": {     "type": "string",     "format": "tel",     "title": "Phone number",     "<http://ory.sh/kratos|ory.sh/kratos>": {       "credentials": {         "code": {           "identifier": true,           "via": "sms"         }       }     }   }

- Make sure your Ory Kratos version supports SMS OTP. - Double-check your configuration for the SMS channel. References: - [Customize identity schema: Phone number and password](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema#phone-number-and-password) - [Enable SMS one-time-code (OTP)](https://www.ory.sh/docs/kratos/passwordless/one-time-code#enable-sms-one-time-code-otp) If you correct the schema key and still see the error, please check your Ory Kratos version and configuration. If the problem persists, let us know your Kratos version and any relevant configuration details.
