Kratos Self Hosted: v1.3.1: Self service registration schema selection not working

[DinkoTontchev]

Hi,
I'm wondering if someone can shed light on this. I'm trying to allow for self service registration using 2 of 3 schemas and according to the docs here: I should be able to create registration flows by passing the extra parameter ?identity_schema=....

Here is my Kratos config running on localhost:4433:

...
identity:
  default_schema_id: user
  # List of available schemas which should be selectable via API but for some only default ever shows up when i run
  # curl -s "http://localhost:4455/.ory/kratos/public/self-service/registration/api?identity_schema=admin"
  # Source docs: https://www.ory.sh/docs/identities/model/identity-schema-selection
  schemas:
    - id: user
      url: file:///etc/config/user.schema.json
      selfservice_selectable: true
    - id: admin
      url: file:///etc/config/admin.schema.json
      selfservice_selectable: false
    - id: realtor
      url: file:///etc/config/realtor.schema.json
      selfservice_selectable: true
 ...

I've verified that my schemas are being loaded on Kratos using this endpoint http://localhost:4433/schemas

[
  {
    "id": "user",
    "schema": {
      "$id": "user",
      "$schema": "http://json-schema.org/draft-07/schema#",
      ...
    }
  },
  {
    "id": "admin",
    "schema": {
      "$id": "admin",
      "$schema": "http://json-schema.org/draft-07/schema#",
      ...
    }
  },
  {
    "id": "realtor",
    "schema": {
      "$id": "realtor",
      "$schema": "http://json-schema.org/draft-07/schema#",
      ...
    }
  }
]

But then when i attempt to request the correct self service registration flow using the param, i always get the default, user, schema no matter what.

curl -s -H 'Accept: application/json'  'http://localhost:4433/self-service/registration/api?identity_schema=realtor' | jq .
// Always returns my default user schema

Can someone please tell me what I am doing wrong?

After looking into the code on GitHub, It appears that the documentation and functionality are not in sync.

Version v1.3.1 is the latest tagged version in the repo and i can confirm that in https://github.com/ory/kratos/blob/v1.3.1/selfservice/flow/registration/handler.go there is no identity_schema parameter that can be passed into the registration handler to overwrite the schema.

In the latest version of main however, https://github.com/ory/kratos/blob/master/selfservice/flow/registration/handler.go, I can see that there is in fact an identity_schema parameter used to overwrite the default:

	// An optional identity schema to use for the registration flow.
	//
	// required: false
	// in: query
	IdentitySchema string `json:"identity_schema"`

It seems I'll have to build Kratos from main. Hope the devs release a new tag soon and in the meantime that main doesn't have other issues.
