Unhandled rejection OrientDB.RequestError: User or password not valid for username: admin, database: 'demodb'

Question

Hy guys, I'm facing some trouble in connecting to an orientdb database.

Here is my app.js code

const express = require('express');
const app = express();
const path = require('path');
const router = express.Router();
const OrientJs = require('orientjs');


var server = OrientJs({
    host: "localhost",
    password: "root",
    username: "root",
    useToken: true
});

var db = server.use({
    name: 'demodb',
    username: 'admin',
    password: 'root',
    useToken: true
});

server.list()
    .then(function (dbs) {
        console.log( dbs.length + ': database/s on the server.');
    });


db.select().from('ArchaeologicalSites').all()
    .then(function (result) {
        console.log(result);
    });

app.set('view engine', 'pug')

router.get('/', function (req, res) {
    res.sendFile(path.join(__dirname + '/views/index.html'));
});

The debugger shows this message even if I try to change the password or the username in the server.use() function.

the message from the debugger:

1: database/s on the server.

So...it correctly connects with server.use(), in fact server.list() works fine. But when itcomes to the query it shows that maybe the var "db" has something wrong...

When i change the app.js to this:

var db = server.use({
    name: 'demodb',
    username: 'root',
    password: 'root',
    useToken: true
});

the error shown is this:
