Custom OIDC provider "auth0" not allowed

I am implementing Auth0 with Supabase, and whilst my user log in the app, no sessions are established with Supabase, new users are not created, tokens are not retrieved, etc.

This is what I see in my browser logs:

Failed to load resource: the server responded with a status of 400 ()
[2025-05-23T02:33:19.470Z] [App] Error signing into Supabase with Auth0 token: AuthApiError: Custom OIDC provider "auth0" not allowed
[App] Stack trace: AuthApiError: Custom OIDC provider "auth0" not allowed

You can in the screenshots that Auth0 is configured as per documentation. I have no idea what is happening and I already tried a whol lot of things to fix it.

Supabase gives you the tools, documentation, and community that makes managing databases, authentication, and backend infrastructure a lot less overwhelming.
