How to connect azure mysql server with nodeJS

I am trying to connect to a remote mysql server with nodejs

So far I am able to connect with mysql workbench 8.0, so no problem with mysql server. And I can easily connect to my local mysql-server (with "mysql2" module).

Here is something I've been trying to connect with remote mysql server provided by Azure. I followed the guides that is provided.

const mysql = require("mysql");
const fs = require("fs")

var connection = mysql.createConnection({
    host: process.env.MYSQL_SERVER_HOST,
    user: process.env.MYSQL_SERVER_USER,
    password: process.env.MYSQL_SERVER_PASSWORD,
    database: process.env.MYSQL_SERVER_DATABASE,
    port:3306,
    ssl: { ca: fs.readFileSync("./certificates/DigiCertGlobalRootCA.crt.pem")}
});

// This is how I am connecting to my local mysql-server which is working fine
// // const connection = mysql.createConnection({
//     host: 'localhost',
//     user: 'root',
//     password: process.env.LOCAL_MYSQL_SERVER_PASSWORD,
//     database: 'db',
//     port: '3306'
// });

connection.connect((error) => {
    if (error) {
        console.log("mysql error")
        console.log(error)
    }
    else {
        console.log("Mysql Ready")
    }
});

module.exports = connection;

Here I am using mysql package because many articles on web suggested it but I even used mysql2 and nothing happened. I even changed the networking setting and allowed my IP address for access(this wasn't necessary though).

Error logs:
