NODE.JS 'ConnectionError with MSSQL

This is the first time I work with javascript and node.js.

I have no idea what the error might be and how to make the connection, my problem initially came up here: link .

I have the following simple code that connects a node server to a database and makes a select only.

    var express = require('express');
var app = express();

app.get('/', function (req, res) {

    var sql = require("mssql");

    // config for your database
    var config = {
        user: 'xxxxxxx',
        password: 'xxxxxxx',
        server: 'devsqlcl2:1433', 
        database: 'xxxxx',
        port: "1433",
        dialect:",ssql",
        dialectOptiond:"SQLEXPRESS"
    };

    // connect to your database
    sql.connect(config, function (err) {

        if (err) console.log(err);

        // create Request object
        var request = new sql.Request();

        // query to the database and get the records
        request.query('select * from dbo.balance_papercut', function (err, recordset) {

            if (err) console.log(err)

            // send records as a response
            res.send(recordset);

        });
    });
});

var server = app.listen(5000, function () {
    console.log('Server is running..');
});

Now I've evolved into this part of node.js, but I'm still 100% lost in how to connect to the bank, however I'm facing the following error below.

I have no idea what it might be. The connection to the bank should not be a problem as I use the same credentials to access by a system in java.
