How to run NodeJS script on beget?

Question

Node.js

New to nodeJS. I'm trying to run node js script on hosting beget. Gives the error that is on the screen. What am I doing wrong?

const express = require('express');
const bodyParser = require('body-parser');
const pdf = require('html-pdf');
const cors = require('cors');


const app = express();

const port = process.env.PORT || 5000;

app.use(cors());
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

app.post('/create-pdf', (req, res) => {

    pdf.create(require('./documents/letter'+req.body.tab_id)(req.body), {}).toFile('result.pdf', (err) => {
        if(err) {
            res.send(Promise.reject());
        }

        res.send(Promise.resolve());
    });
});

app.get('/fetch-pdf', (req, res) => {
    res.sendFile(`${__dirname}/result.pdf`)
})

app.listen(port, () => console.log(`Listening on port ${port}`));

Apparently you have Virtual Shared Hosting and Node is launched through the Passenger Apache module. This is a very limited mode and there is a lot of things that are not allowed. In particular, you cannot listen on ports like you do. Express uploads static files via Node stream and it doesn't work on such hosting either. You need to change your hosting plan to VPS/VDS.
