Nginx ngx-http-auth-jwt-module does not work with Auth0


did anyone try to engage this third party Nginx module to authenticate with Auth0?

I setup authentication request to Auth0 via an URL similar to:

Auth0 tenant logs say login is successful, but the module does not receive the famous JWT containing user email. I checked headers sent along with the callback from Auth0, there is no such.
Am I missing any invocation parameter/s in the authentication request?

Thanks !
