didReceiveRegistrationToken Error #79

Closed mattnickcodes closed 3 years ago

mattnickcodes commented 3 years ago

After installation of @capacitor/push-notifications and @capacitor-community/fcm I am able to receive push notifications but I am not able to receive a registration token to send messages to individual users.

Here is the error I'm getting:

[Firebase/Messaging][I-FCM002023] The object <FCMPlugin: 0x282382dc0> does not respond to -messaging:didReceiveRegistrationToken:. Please implement -messaging:didReceiveRegistrationToken: to be provided with an FCM token.

I suspect you didn't update AppDelegate for Capacitor v3

Take a look in the repo example and review Capacitor's migration guide. There was some breaking changes.

Can you provide a reproducible example?

The solution is making sure the FCM.getToken() function is not called/triggered by any of the PushNotifications functions.

The code I wrote here causes this particular error. I believe it happens because the registration event is being fired before FCM initializes. PushNotifications.addListener('registration', () => { FCM.getToken().then((token: any)=>this.saveToken(token.value)) });

Glad you figured it out.
