I get those message when building for IOS, it succeed but IOS notification don't work, i get the messaging/registration-token-not-registered by FCM, so I thought this post may have been related to this error.
It's saying that my registration token is not registered. After looking into the firebase doc i saw that : https://firebase.google.com/docs/cloud-messaging/send-message#admin_sdk_error_reference
messaging/registration-token-not-registered :
The provided registration token is not registered. A previously valid registration token can be unregistered for a variety of reasons, including:
The client app unregistered itself from FCM The client app was automatically unregistered.(This can happen if the user uninstalls the application or, on iOS, if the APNS Feedback Service reported the APNS token as invalid.) The registration token expired. (For example, Google might decide to refresh registration tokens or the APNS token may have expired for iOS devices.) The client app was updated, but the new version is not configured to receive messages. For all these cases, remove this registration token and stop using it to send messages.
But i feel like i already filled all the requirement (APNS is already configured and added into Firebase console)
