Node.js - mssql bağlantısı problemi

Merhabalar. İnternetten https://www.youtube.com/watch?v=MLcXfRH1YzE gibi birçok yöntemi denememe rağmen mssql ve node.js bağlantısı kuramadım. Bu konuda yardımcı olabilir misiniz ?

En son denediğim kod : 

var sql = require('mssql');

var sqlConfig = {
    server: 'DESKTOP-LCEVO44',
    database: 'Person',
    user: 'sa',
    password: '123456789',
};
(async function () {
    try {
        console.log("sql connecting......")
        let pool = await sql.connect(sqlConfig)
        let result = await pool.request()
            .query('select * from People')  // subject is my database table name

        console.log(result)

    } catch (err) {
        console.log(err);
    }
})()

kodun verdiği hata / çıktı :
