[jkasztur]

Hi, I updated the provider like in this PR #21
to use this in Keycloak 16.1.1

my configuration looks correct accorging to Readme

After trying to login, I get redirected to apple, fill credentials, but when getting back to keycloak page, i see Unexpected error when authenticating with identity provider
In keycloak logs there is this:

I found out I had a broken mapper in apple provider(dont remember how broken). But if I remember correctly, all I did is delete mapper/all mappers and recreate them
