Hey there, Thiago. Sorry that you expired this issue and thank you very much for reporting it t us.

Luckily, the stacktrace is helpful. It looks like you have sent a push notification to a device with an image attached. The code throws an error because the URL to the image does not contain a protocol.

I am going to guess that the image URL in the push composer in fly.customer.io does not contain https:// or http:// at the beginning of it. Could you verify this by sending us an example of a push notification you have composed that caused this issue when you sent it to a device?

The SDK should be able to handle this situation without encountering an error so we will be sure to fix the code. In the meantime, as a workaround, if you make sure to add https:// to the image URL in fly.customer.io, does this fix your issue when you send the push to the device?

Hi @levibostian , thank you for response.

In fact, the push notification I sent did not have any image attached, just the title, message and a deeplink, i was intercept the message in debug and the field image was empty.

My implementation:

FirebaseMessaging.onMessage.listen((event) async {
    try {
      CustomerIO.messagingPush().onMessageReceived(event.toMap()).then(
        (handled) {
          if (handled) {
            saveNotification(event);
          }
        },
      );
    } catch (_) {}
  });

  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

  @pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
  try {
    CustomerIO.messagingPush()
        .onBackgroundMessageReceived(message.toMap())
        .then(
      (handled) {
        if (handled) {
          saveNotification(message);
        }
      },
    );
  } catch (_) {}
}

And an observation, despite the error, the message was displayed successfully and handled returns true, but I have ANRs in the play console with this coroutine blocking io.customer.messagingpush.CustomerIOPushNotificationHandler.addImage

[levibostian]

Thank you for those additional details. Very helpful!

The addImage function that you mention (and the stacktrace shows) should only be called when the push notification payload has a image key in the JSON.

Could you send me the push notifications that caused this issue? I am looking for https://fly.customer.io URLs for the push notification you created and used to send the push to the device.

How can i send?

[levibostian]

Feel free to send an email to win@customer.io instead of this public github issue. Be sure in your email to reference this github issue so the message gets directed to our team.

[thiaagodev]

Ok, i will send
