Hi everyone,
I am looking to change Authentication Scheme of my application to use Auth0. These are the settings I created my Auth Scheme with.

I was not sure about the scope and username attribute, so I kept it as the default values.
Also, after this step. I had to register the URL https://intranet.example.net/dev/apex_authentication.callback with the Auth backend guys.
Now when I try logging i, I get the following error

Am I doing something wrong?
