FCM notification title remains "FCM Message"

I'm trying to use the Firebase Cloud Messaging. I send the notifications from a Node.js server to my apps that are registered to the notification system.

My problem is that on Android 5.1 the notification is "FCM Message" even if I setted the title attribute in the nofitification json. It works fine in Android 6.0. I tried to reboot my device as well.

enter image description here

And this is the code I use to send the notification:

function sendNotificationToUser(userToken, message, onSuccess) {
request({
url: 'https://fcm.googleapis.com/fcm/send',
method: 'POST',
headers: {
'Content-Type' :' application/json',
'Authorization': 'key='+API_KEY
},
body: JSON.stringify({
notification: {
"title": 'My App Name',
"body": message,
"sound": 'default'
},
to : userToken
})
}, function(error, response, body) {
if (error) { console.error(error); }
else if (response.statusCode >= 400) {
console.error('HTTP Error: '+response.statusCode+' - '+response.statusMessage);
}
else {
onSuccess();
}
});
}


As you can see the notification title I send is "My App Name" but on device it shows "FCM Message".

What do I have to do?!

Answer

I found that it is a problem related to onMessageReceived callback.

As you can see on the receive a FCM guide
