I'm implementing Sign In with Apple into my website but I'm receiving an error during user authentication.
I've sent a valid authorization request, I've authenticated, completed 2FA, but then a JS request is made to https://appleid.apple.com/appleauth/auth/oauth/consent which results in an HTTP 500.
Any ideas what's wrong? Am I missing some config? Could it be because I only signed up for a dev program today?
