"An internal server error has occurred" in keycloak after Apple sign in

[hvma411]

Hello there,

I have a problem after successful apple auth. I checked a few times and all my credentials provided in provider settings are correct but redirecting after apple sign in creates error "An internal server error has occurred" in keycloak. My keycloak version is 21.1.0. I checked keycloak logs and this is what it says:
