Connecting to OrientDB in NodeJS using OrientJS module -- "Socket Closed" Error

Question

I'm developing an application in NodeJS (v8.11.3) using OrientJS (v2.2.10) that will connect to a locally-hosted OrientDB (v3.0.6) database and query it. However, when I attempt to run my program, I receive a "Socket Closed" error every time.

I am able to connect to the database and query it through both OrientDB's console and through the web-interface, so I know the database is accessible at the address http://localhost:2480. If I run "netstat -a" in the Command Prompt, I can see that port 2480 is Listening for a TCP connection.

This is the code I am currently running:

//Import OrientJS driver for OrientDB
var OrientJs = require('orientjs');

//Connect to OrientDB server
var server = OrientJs({
    host: "localhost",
    port: "2480",
    username: "root",
    password: "root"
});

//Connect to 'demodb'
var db = server.use({
    name: 'demodb',
    username: 'root',
    password: 'root'
});

console.log("Connected to database")

//Select all entries in 'Castles' table and print to console
db.select().from('Castles').all()
.then(function(result) {
  console.log(result);
});

//Close connection to database
db.close();

The error I receive is:

Unhandled rejection OrientDB.ConnectionError [0]: Socket Closed
    at Connection.<anonymous> (C:\Program Files\nodejs\apollo_server\node_modules\orientjs\lib\transport\binary\connection.js:277:16)
    at Object.onceWrapper (events.js:313:30)

    at _combinedTickCallback (internal/process/next_tick.js:138:11)
    at process._tickCallback (internal/process/next_tick.js:180:9)

I'm not sure what to make of this error, as the database appears to be running fine. I was not able to find any useful information through googling this error; googling ""orientjs" "socket closed"" returns only 1 result, so I'm at a bit of a loss as to how to tackle this problem.

Any insight is greatly appreciated!

After further investigation, I've found the source of the problem.

As it turns out, OrientDB hosts its service on two ports: 2480 (HTTP) and 2424 (Binary). Connecting to OrientDB via the OrientJS module requires using port 2424 rather than 2480. This solved my problem.
