Issue with callback & promise style.

[vaibhavmagon]

Both of these styles to send notification (promise and callback) fail when used default syntax.

Here is better way to send:

var message = {
to: ele.token,
data: {
pn_title: ele.title,
pn_body: ele.body
},
notification: {
title: ele.title,
body: ele.body
}
};

return new Promise((resolve, reject) => {
const options = {
host: "fcm.googleapis.com",
path: "/fcm/send",
method: 'POST',
headers: {
'Authorization': process.env.authorization,
'Content-Type': 'application/json'
}
};
fcm.send(message, function(err, res) {
if(err) {
reject(err);
}
else {
resolve(res);
}
});

});
