'Sign in with Apple: Authorization Error 1000 (Unknown)

I use "Sign in with Apple" using this package: https://pub.dev/packages/sign_in_with_apple

  • I can login successfully on iPhone (real device)
  • I can login successfully on iPad (real device)
  • I can login successfully on a few type of Simulator

I sent the app for review, but the Apple review team cannot login successfully.

They sent me a screenshot of the error they get:

Unknown Error: 1000

App Store Review Team's device:

  • Device type: iPad
  • OS version: iOS 15.2

What I tried:

  • Added "Sign in with Apple" capability (for debug, release, profile modes) in the "Signing & Capabilities" section in the Xcode.
  • Removed my app from the "Apps Using Apple ID" and tried to login again.
  • Tried on another device (iPad) using Testflight and logged in successfully.

How can I solve this?



Solution 1:[1]

I created 3 different provisioning profiles bug debug, profile and release and added "Sign in with Apple" capability. Then it's worked.

Solution 2:[2]

You need to add "Sign in with Apple" inside Signing & Capabilities, this should work for Apple Authorization Error 1000.
