iOS Firebase token fetching issue

Question

I am receiving this issue when fetching token via iOS out of sudden. We managed to get this error message via debugging as a lot of device cannot receive push notification. Is this a firebase server issue or provisioning profile configuration issue?

[Firebase/InstanceID][I-IID003009] Failed to fetch default token Error Domain=com.firebase.installations Code=2 "Too many server requests."

I had the same issue. The problem was in the deprecated Firebase API. If you use InstanceID.instanceID().instanceID method for fetching token, then you need change it to Installations.installations().installationID { (token, error) in } from FirebaseInstallations framework.
