React Native, Sign in With Apple Error {code: '1000', domain: 'com.apple.AuthenticationServices.AuthorizationError', message: 'The operation couldn't be completed. (com.apple.AuthenticationServices.AuthorizationError error 1000.)'

What went wrong

While trying to implement Sign in with Apple in React Native, I ran into the following error.

It failed on both the simulator and a real device, and I couldn't log in.

{code: '1000', domain: 'com.apple.AuthenticationServices.AuthorizationError', message: 'The operation couldn’t be completed. (com.apple.AuthenticationServices.AuthorizationError error 1000.)'

The fix

In my case, the Debug field for the second item was blank, and that's what was causing the error above.
