[firebase-admin-7.0.0] No enum constant com.google.firebase.ErrorCode.UNIMPLEMENTED
The above error suddenly appeared. I checked the source code and found that there was no UNIMPLEMENTED object in ErrorCode. Does anyone know why?
I changed to version 9.2.0 but it still doesn't work. What else could be the problem?
I faced the same issue and changed
BatchResponse response = firebaseMessaging.sendMulticast(message);
to
BatchResponse response = firebaseMessaging.sendEachForMulticast(message);
also updated to version 9.3.0 and its working fine for me.
