On using multiple webhooks, when the first webhook is successful and gives a status 200, i get an error saying

{
  "id": "b7593ca3-1bda-4ba2-93f6-c13490ed1a71",
  "error": {
    "code": 500,
    "status": "Internal Server Error",
    "message": "hook response could not be unmarshalled properly from JSON: invalid character 'S' looking for beginning of value"
  },
  "created_at": "2023-03-22T08:34:47.049429Z",
  "updated_at": "2023-03-22T08:34:47.049429Z"
}

my webhooks config

registration:
      lifespan: 10m
      ui_url: <http://127.0.0.1:3000/registration>
      after:
        password:
          hooks:
            - hook: web_hook
              config:
                url: <http://host.docker.internal:4000/api/v1/web-hooks/ory-identities/check-user-in-invite>
                method: POST
                body: <base64://ZnVuY3Rpb24oY3R4KSB7CiBlbWFpbDogY3R4LmlkZW50aXR5LnRyYWl0cy5lbWF>pbCwKIGN0eDogY3R4Cn0=
                can_interrupt: true
            - hook: web_hook
              config:
                url: <http://host.docker.internal:4000/api/v1/web-hooks/ory-identities/generate-key-for-registered-user>
                method: POST
                body: <base64://ZnVuY3Rpb24oY3R4KSB7CiBlbWFpbDogY3R4LmlkZW50aXR5LnRyYWl0cy5lbWF>pbCwKIGN0eDogY3R4Cn0=
                can_interrupt: true
            - hook: session

this is how my api returns the error (ory reacts properly incase of error)

return res.status(404).json({
      messages: [
        {
          instance_ptr: "#/traits/email",
          messages: [
            {
              id: 123,
              text: "Not found in waiting list",
              type: "validation",
              context: {
                value: "not allowed",
              },
            },
          ],
        },
      ],
    });

this is how i return success (ory is unable to handle even when status code is 200)

return res.status(200).send("Success");

"Success" isn't valid json. It would most likely need to be something like

{
  "message": "success"
}

On the latest commit of Kratos there is support for

config.response.parse: false

https://www.ory.sh/docs/guides/integrate-with-ory-cloud-through-webhooks#modify-identities

tried this doesn't work

Are you using the latest commit from master?

the thing is it shouldn't interrupt the flow if the request gives 200 status. but it still does

the thing is it shouldn't interrupt the flow if the request gives 200 status. but it still does

Yes because the json marshalling is failing. This isn't returning valid json:

return res.status(200).send("Success");

Instead it should be:

return res.status(200).send({"message":"success"});

okay

is it fixed in next release?

Nothing needs to be fixed if valid json is returned. But if you want to prevent the webhook from parsing the response then you need the latest commit from master

understood

We do releases each quarter https://www.ory.sh/docs/open-source/commitment#binary-and-docker-releases But can't say exactly when we will do so

got it
