MEAN Stack Cannot Update MongoDB Record using PUT method - node.js

Question

Cannot update mongoDB record, using PUT method. Parameters are passing correctly, there must be a problem within a query I guess.
Schema
let Boards = new mongoose.Schema({
title: String,
description: String,
lastUploaded: Number,
owner_id: String
});
Server:
module.exports.updateTime = function (req, res) {
let board = new Board();
let id = new mongoose.Types.ObjectId(req.body._id);
let myquery = { _id: id };
let newvalues = { lastUploaded: req.body.time };
console.log("New time: " + req.body.time); //Number recieved
console.log("Id: " + req.body._id); //String recieved
board.findByIdAndUpdate(myquery, newvalues, function (err, response) {
if (err) {
response = { success: false, message: "Error updating data" };
} else {
response = { success: true, message: "Data updated" };
}
res.json(response);
});
board.close();
};
Client:
public updateTime(updateOptions: UpdateTime): Observable<any> {
let headers = new Headers;
let URI = `${apiUrl}/updateTime`;
headers.append('Content-Type', 'application/json');
return this.http.put(URI, updateOptions, { headers: headers })
.map(this.extractData)
.catch(this.handleError);
}
Router:
router.put('/updateTime', ctrlContent.updateTime);
Finally gave me empty response error through .catch(this.handleError);

There are two bugs that I can see.
First, the first argument to the findByIdAndUpdate method should be an _id itself, not an object with an _id property:
// this will not work
board.findByIdAndUpdate({ _id: id }, newvalues, handler);
// this is how it should be
board.findByIdAndUpdate(_id, newvalues, handler);
Second, you are calling board.close(); outside of the query callback. Closing a connection is propably a mistake, but even if you absolutely need it, you should do it inside the callback function.
Here is a complete server example:
module.exports.updateTime = function (req, res) {
let id = req.body._id;
let newvalues = { lastUploaded: req.body.time };
Board.findByIdAndUpdate(id, newvalues, function (err, response) {
if (err) {
res.json({ success: false, message: "Error updating data" });
} else {
res.json({ success: true, message: "Data updated" });
}
});
};
