Discord invalid request at test mode

Hello, everyone!

I’m new to auth0
My discord connection in returning this in test mode:

  "error": "invalid_request",
  "error_description": "null"

I passed my redirect URI https://my-tenant-domain.auth0.com/login/callback in discord OAuth2 Redirects section

The scopes > identify return me an URL with arguments that is supposed to grant the necessary scopes to auth0 but wherever I insert it, won’t work. Someone has any idea what is going wrong?

Thanks in advance!
