invalid_client error

I'm getting a weird invalid_client error trying to implement Sign in with Apple using this gem.

It is always failing on this line:

token_response = @client.access_token!

I've included in the snippet above my @client variable.

Any ideas here? This is my second run (first run was with the Apple Omniauth gem) at implementing this and have been stuck for hours trying to get basic Apple Signin to work.

Every thing works fine routing to Apple and authenticating, but the callback fails.

debug raw http messages by using AppleID.debug! & curl etc. maybe client credential is wrong
