Visual popup on bad user or password

[timmo001]

Problem

When the username or password is incorrect, a window pops up with an error. I am using a purely server-side application which cannot rely on a visual popup blocking any further execution.

Requested changes

Stop the dialog from appearing on bad login credentials

Usage

const config = { host: req.hostname, user: req.username, password: req.password };
const pool = require('node-jt400').pool(config);
