Authorization failed: Error Domain=AKAuthenticationError Code=-7003 "(null)"

In the following environment: iOS 14 beta, Xcode Version 12.0 beta 6 (12A8189n) try to implement user Apple Login with Firebase. Works until password entering screen and then hangs up on simulator or finished with error on device. Sign In with Apple is enabled in App.
I have this problem too, on Emulator iOS 14.2 Xcode v.12
I have this problem too
I have this problem when i try to Login in FireBase where don't have this user! If user have in FB so Ok
Do you guys have the solution yet?

Is there not a list of error codes somewhere where we can look it up? Seems strange to be given an error code by Apple but no reference to it

Yes i am also facing same error

It appears that this error is often related to server/configuration changes on Apple's end. Until they decide to post more information/status submit a ticket.
