ELOGIN error while connecting to the SQL server - node.js

Question

I'm learning full stack web development and was trying to connect to SQL server from my backend Node.js. I was following an online video. While running the index.js file I get the below error -
ConnectionError: Login failed for user 'systemadmin'.

undefined
[nodemon] clean exit - waiting for changes before restart
The code is as follows
const sql = require("mssql");
const config = {
user: "systemadmin",
password: "R#jasthaan1212",
server: "localhost",
database: "ORG_EMPLOYEEDATA",
options: {
trustedconnection: true,
trustServerCertificate: true,
enableArithAbort: true,
instancename: "SQL2019",
},
port: 50685,
};
async function getEmployeeName() {
try {
let pool = await sql.connect(config);
let employeeData = await pool
.request()
.query("select * from dbo.EMPLOYEES_DATA");
return employeeData.recordsets;
} catch (error) {
console.log(error);
}
}
module.exports = { getEmployeeName: getEmployeeName };
const dboperations = require("./dboperations");
dboperations.getEmployeeName().then((result) => {
console.log(result);
});
Please let me know what exactly I'm missing here. I couldn't find the way to resolve this by searching in internet as well, may be I'm terrible at searching. Any help to resolve this is appreciated.
