Having an issue trying to automate sign in after registration with auth.js. I can see the session cookie is being created (verified at sessions/whoami) but when trying to silently authenticate I get "The Authorization Server requires End-User authentication. Prompt none was requested but no existing login session was found". Is this a consent issue? I've also tried "skip_consent": true and in the OAuth2 Client config 'Skip consent' is checked. Any ideas on how to fix this?
