Node.js/Firebase: Notifications won't reach device - node.js

Question

A few months ago i started using Firebase's backend tools. they're awesome. So i had to move our current method of notifying users of their to-do list. We moved to Cloud Functions and it was 40x faster. Until a week ago i got a fresh copy of MacOS i had to delete everything in my Solid State Drive. When i did i also installed the firebase command line tools. I had my code which i used to notify users, it suddenly stopped working
Here's what happens:
When someone adds a new record to our daily list. the app notifies other family members about the new record. So i had to come up with a method to do so..
OLD CODE (worked seamlessly)
const functions = require('firebase-functions');
var admin = require("firebase-admin");
admin.initializeApp();
var registrationToken = 'egV-C3ItwJE:APA91bGf5ezSRQQFHkzCNzfqhS6tiKRbs6IXXs57DFTrNCWRrVY0pZ4PHsK8G3ZjvvvO4JCvd13j_jBcJkgRh06YJ5Jw6tohc81Ro0k4HdHG-Jlv4sbW5t1DNmJBDeGf48l05eDlfMGO';
var payload = {
data: {
title: 'TEST/2',
body: 'TEST/2'
}
};
// registration token.
admin.messaging().sendToDevice(registrationToken, payload)
.then((response) => {
// Response is a message ID string.
console.log('Successfully sent message:', response, payload);
return
})
.catch((error) => {
console.log('Error sending message:', error);
});
Back in my previous version of macOS this code had no issues. upgrading Firebase Command Line tools i had to make some edits to the code:
NEW CODE (NOT WORKING)
// This registration token comes from the client FCM SDKs.
var registrationToken = 'egV-C3ItwJE:APA91bGf5ezSRQQFHkzCNzfqhS6tiKRbs6IXXs57DFTrNCWRrVY0pZ4PHsK8G3ZjvvvO4JCvd13j_jBcJkgRh06YJ5Jw6tohc81Ro0k4HdHG-Jlv4sbW5t1DNmJBDeGf48l05eDlfMGO';
// See documentation on defining a message payload.
var message = {
data: {
title: '850',
body: '2:45'
},
token: registrationToken
};
// Don't use the legacy sendToDevice
admin.messaging().send(message)
.then((response) => {
// Response is a message ID string.
console.log('Successfully sent message:', response);
return
})
.catch((error) => {
console.log('Error sending message:', error);
});
The Problem is:
1- When this function hits. i get the "Successfully sent message:" response. but the message won't reach the device
Things i have tried:
1- The device token is correct and i have tested it using the manual push notification on single devices
2- The device receives notifications.
3- The device runs on iOS 11.1 same as before
Thanks

Can u check with this function,I had tried with this I am able to get notifications.
In you first code sample u had user sendToDevice but in second sample you had used send
function sendPushNotification(fcmtoken, notificationTitle, notificationMessage) {
if (fcmtoken != null && fcmtoken != "" && fcmtoken != " ") {
var payload = {
notification: {
title: notificationTitle,
body: notificationMessage,
sound: "default"
}
};
admin.messaging().sendToDevice(fcmtoken, payload)
.then(function (response) {
}).catch(function (error) {
console.log("Error sending message:", error);
});
}
}
