Check User Profiles

Is user profile information correct at the source (authorization server)?

Generate and check the HAR file, look for an id_token.

Decode the id_token at JWT.io to see if it has the correct information.

Check any custom database scripts or rule logic.

Check if you called /tokeninfo endpoint and have a custom domain configured within Auth0. If so, you need to use /userinfo endpoint instead

Check if you called /userinfo endpoint properly. You should pass an access token. You should call this endpoint with the default Auth0 domain even if the tenant has a custom domain enabled.

Check if you specified the correct scope to get an Access Token.
