Estou encontrando um erro ao tentar obter o token usando o Firebase Messaging no meu aplicativo Flutter iOS. A mensagem de erro é a seguinte:
FLTFirebaseMessaging: An error occurred while calling method Messaging#getToken, errorOrNil => { NSLocalizedFailureReason = "Invalid fetch response, expected 'token' or 'Error' key";}
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: [firebase_messaging/unknown] An unknown error has occurred.

Até ontem estava funcionando bem, de repente ocorreu esse erro. Como resolver isso?
