Trying to use auth0 as an OAuth server for a ChatGPT MCP Connector

I am trying to use Auth0 with ChatGTP with an MCP Connector. but the access token generated at the end returns an empty body in the UserInfo Endpoint.

At the end of the authentication flow, I obtain an access token which I validate in the /userInfo endpoint. The UserInfo Endpoint returns 200 but an empty body.

Based on similar questions, I assume ChatGPT is not requesting the `openid` scope when obtaining the token.

I am trying to see in the Auth Monitoring / Logs the scopes being requested.

Is there any thing I can do? I cannot see the logs and I don’t have control over the scopes being requested.

Same MCP server with Auth0 and Claude works seamlessly.
