Getting ENOENT error using node.js and MySQL - node.js

Question

I am following the node tutorial on https://dev.to/achowba/build-a-simple-app-using-node-js-and-mysql-19me , to build a node application with Mysql. I'm getting the error "ENOENT path: public/assets/img/image name" which I have been able to trace to the line uploadedFile.mv('public/assets/img/${image_name}', (err ) => { in the file player.js.
I have tried fs.writeFile and fs.copyFile to no avail. Any help will be appreciated.
PLAYER.JS
const fs = require('fs');
module.exports = {
addPlayerPage: (req, res) => {
res.render('add-player.ejs', {
title: "Welcome to Socka | Add a new player"
,message: ''
});
},
addPlayer: (req, res) => {
if (!req.files) {
return res.status(400).send("No files were uploaded.");
}
let message = '';
let first_name = req.body.first_name;
let last_name = req.body.last_name;
let position = req.body.position;
let number = req.body.number;
let username = req.body.username;
let uploadedFile = req.files.image;
let image_name = uploadedFile.name;
let fileExtension = uploadedFile.mimetype.split('/')[1];
image_name = username + '.' + fileExtension;
let usernameQuery = "SELECT * FROM `players` WHERE user_name = '" + username + "'";
db.query(usernameQuery, (err, result) => {
if (err) {
return res.status(500).send(err);
}
if (result.length > 0) {
message = 'Username already exists';
res.render('add-player.ejs', {
message,
title: "Welcome to Socka | Add a new player"
});
} else {
if (uploadedFile.mimetype === 'image/png' || uploadedFile.mimetype === 'image/jpeg' || uploadedFile.mimetype === 'image/gif') {
uploadedFile.mv(`public/assets/img/${image_name}`, (err ) => {
if (err) {
return res.status(500).send(err);
}
// send the player's details to the database
let query = "INSERT INTO `players` (first_name, last_name, position, number, image, user_name) VALUES ('" +
first_name + "', '" + last_name + "', '" + position + "', '" + number + "', '" + image_name + "', '" + username + "')";
db.query(query, (err, result) => {
if (err) {
return res.status(500).send(err);
}
res.redirect('/');
});
res.redirect('/');
});
});
} else {
message = "Invalid File format. Only 'gif', 'jpeg' and 'png' images are allowed.";
res.render('add-player.ejs', {
