Anyone has implemented login by Apple id with AWS Cognito? We are not receiving the name attribute in authentication token from apple which is mandatory in Cognito. Please let me know if you have faced the similar issue.
AWS Cognito - Signinwith Apple - Not receiving the name attribute in authentication token from apple
This is a known issue with apple sign-in and Cognito. Apple doesn't provide user info on subsequent logins, so if the cognito user pool requires "name" or "email", the login will fail.
I would suggest not supporting "Sign-In With Apple" but since they force you to use it (for no real reason?) that doesn't seem to be a viable solution. Just another instance of anti-developer/anti-consumer behaviour on the case of Apple.
