    This error means that you registered the app under Azure AD rather than Azure AD B2C. Even though you can see the app under Azure AD B2C, it doesn't mean you created it there.

    You should navigate to Azure AD B2C to register the application. If you don't already have a B2C tenant, you can create one.
