problems sending Firebase message with data

Question

I am able to successfully send a title/text message using pyfcm:

result = push_service.notify_multiple_devices(registration_ids=registration_tokens, message_title="title",
                                                  message_body="testing")

But when I try to send a data message, it fails:

    payload = {
        'action': 'testing',
        'test number': 1,
        'question': "what do you do with a klondike bar?",
    }
    result = push_service.multiple_devices_data_message(registration_ids=registration_tokens, data_message=payload)

In the first case, I receive the text/message in my FirebaseMessagingService on the phone in the onMessageReceived method as expected. In the second case (dictionary data payload), it is never received:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    RemoteMessage.Notification data = remoteMessage.getNotification();
    System.out.print("here");
}

In both cases, result seems to be a success.

Any suggestions would be most welcome!

Could you print the actual value of the `payload` in the second case? — AL., Jan 15 '19 at 11:30
payload = { 'action': 'testing', 'test number': 1, 'question': "what do you do with a klondike bar?", } — jordanthompson, Jan 16 '19 at 13:21
Err... Shouldn't that payload items be enclosed in either a `notification` or `data` parent? — AL., Jan 16 '19 at 18:48
I'm following the directions at https://pypi.org/project/pyfcm/. There is no mention of either a notification or data parent. — jordanthompson, Jan 18 '19 at 18:59

There seems to be a problem with multiple_devices_data_message

I tried this:

result = push_service.single_device_data_message(registration_id=registration_tokens[0], data_message=payload)

and it worked as expected. So to solve my problem for now, I will need to iterate over each registration token, calling single_device_data_message for each one
