Sending Custom Data in FCM not working

[imarc7]

Sending custom data with FCM is not working. When trying to log the notification received in Expo React Native, no custom data is received.
Here's the code:

const settings = {
  fcm: {
        appName: 'xxxxx',
        serviceAccountKey: jsonKey, 
        credential: null,
   }
}
const push = new PushNotifications(settings);
const deviceToken = 'xxxxxxxxxx';
const data = {
      title: 'XXXX',
      body: 'Message',
      custom: {
        // Additional data to send with the notification for android
        name: 'test'
      },
    };
push.send(deviceToken, data, (error: Error, result: any) => {
});

The notification is received but the custom param "name" is not there.

Same issue here...

seems to be a problem with expo, doesn't it ?

Hey guys. Let us know if you can confirm that this is an issue with expo.
Otherwise we'd be happy to accept PRs for fixing whatever issue this is for your use-case.

i experienced the same problem. i am not using Expo just nativescript for my app.

The problem seems to be due to the migration of the new http api of FCM. my problem was that after migration it seems the data-only notification was not send anymore. Also the android_channel_id property is now just channel_id (although i am currently not using it anymore thus you will not find it in the code below)

anyhow, this is working for me now:

const data = {
                    collapseKey: Math.random().toString().replace('0.', ''),
                    title: 'test',
                    topic: 'all',
                    body: 'text',
                    priority: 'high',
                    custom: {
                        id:'123',
                    },
                    fcm_notification: {
                    },
                    icon: 'notification_icon',
                    sound: 'test.wav',
                    category: 'alarm',
                    truncateAtWordEnd: true,
                    pushType: 'alert',
                };
                const pushResult = await push.send(result.user.fcmToken, data);

strangely i need to put the empty fcm_notification object into it, because otherwise https://github.com/appfeel/node-pushnotifications/blob/master/src/utils/tools.js#L77 will create these properties for a notification message it seems and then my custom messaging service is not invoked on the android client side. Really strange, but this was doing the trick for me. hopefully this also helps others
