How to access profile picture in github OIDC

[spa5k]

Hey, I'm trying to add a separate field into the schema that will be filled with the user's avatar after he does oidc with github, but im not able to fill up that field.

local claims = {
  email_verified: false
} + std.extVar('claims');
{
  identity: {
    traits: {
      [if "email" in claims && claims.email_verified then "email" else null]: claims.email,
      [if "avatar_url" in claims then "avatar_url" else null]: claims.avatar_url,
    },
  },
}

here is my schema

{
  "$id": "https://schemas.ory.sh/presets/kratos/quickstart/email-password/identity.schema.json",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Person",
  "type": "object",
  "properties": {
    "traits": {
      "type": "object",
      "properties": {
        "email": {
          "type": "string",
          "format": "email",
          "title": "E-Mail",
          "minLength": 3,
          "ory.sh/kratos": {
            "credentials": {
              "password": {
                "identifier": true
              }
            },
            "verification": {
              "via": "email"
            },
            "recovery": {
              "via": "email"
            }
          }
        },
        "avatar_url": {
          "type": "string",
          "description": "User's avatar pic",
          "title": "Avatar"
        }
      },
      "required": ["email"],
      "additionalProperties": false
    }
  }
}

But after i login /register in a clean env, it only adds email traits into the trait column of identities table.

{
  "email": "[email protected]"
}

A help on this topic will be greatly appreciated

I was able to fix it by adding these extra things into kratos.yml

        providers:
          - id: github
            provider: github
            client_id:  # Add the client ID
            client_secret:  # Add the client secret
            mapper_url: file:///etc/config/kratos/oidc.github.jsonnet
            scope:
              - user:email
            requested_claims:
              userinfo:
                given_name:
                  essential: true
                nickname: null
                email:
                  essential: true
                email_verified:
                  essential: true
                picture:
                  essential: true

then in oidc.github.jsonnet

local claims = {
 email_verified: false
} + std.extVar('claims');

{
 identity: {
   traits: {
     [if "email" in claims && claims.email_verified then "email" else null]: claims.email,
     [if "picture" in claims then "picture" else null]:claims.picture,
   },
 },
}

and in schema like this instead of the old avatar_url field-

     "picture": {
          "type": "string",
          "description": "User's avatar pic",
          "title": "Picture"
     }
