APNS - Node APN - payload - single quote - json

Question

I am testing push notification using the node-apn module in node js. All works fine except that special characters such as a single quote does not properly escape. The push notification with a single quote (i.e. we'll becomes we\'ll in the actual notification). I tried regex, mongoose.toObject, message.message.toString() to no avail.
Message.findOne(query).lean().exec(function (err, doc){
if (!doc || doc == null) {
message.save(function(e) {
console.log("message saved")
if (e) {
console.log("there is an error")
console.log(e)
} else {
console.log(message.device_token)
var mesg = message.toObject();
var msg = JSON.stringify(mesg);
var payload = {
"contact" : message.contact,
"did" : message.did,
"id" : message.message_id,
"date" : message.date,
"message" : message.message
}
var clean = message.message.toString().replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");
var note = new apns.Notification();
var myDevice = new apns.Device(message.device_token);
note.expiry = Math.floor(Date.now() / 1000) + 3600; // Expires 1 hour from now.
note.badge = 3;
note.alert = message.message;
note.payload = payload;
apnsConnection.pushNotification(note, myDevice);
}
})
}
});
});

I solved this issue by escaping the json formmatted single quote (which was //') in the message.message value using the replace function:
var messageStringCleaned = message.message.toString().replace(/\\/g,"");
var payload = {
"contact" : message.contact,
"did" : message.did,
"id" : message.message_id,
"date" : message.date,
"message" : messageStringCleaned
}
var note = new apns.Notification();
var myDevice = new apns.Device(message.device_token);
note.expiry = Math.floor(Date.now() / 1000) + 3600; // Expires 1 hour from now.
note.badge = 3;
note.alert = messageStringCleaned;
note.payload = payload;
apnsConnection.pushNotification(note, myDevice);
