ExpressJS app not responding

Hello! I am currently trying to deploy my ExpressJS app with only one basic feature. It works on localhost. But on the deployed domain I see none of the console log's in the deploy page and also get no responses when making API requests to it, using CURL. Here's my code:

import express from "express";
import { Readable } from "stream";
const app = express();

const messages = ['Hey!', 'How are you?', 'Thanks suXin for help :birb:']; 

app.get('/', (req, res) => {
    console.log("New request");
    var i = 0;
    res.setHeader('Content-Type', 'text/plain');

    const readable = new Readable();
    readable._read = () => {}; // Required for a readable stream

    const interval = setInterval(() => {
        readable.push(`${messages[i]}\n`);
        console.log(messages[i]);
        i++;

        if (i >= messages.length) {
        clearInterval(interval);
        readable.push(null); 
        }
    }, 1000);

    readable.pipe(res);
});

app.get("/health", (req, res) => {
    res.status(200).send({
        status: "OK"
    });
})

app.listen(3000, () => {
    console.log("Listening on port 3000");    
});

import express from "express";
import { Readable } from "stream";
const app = express();

const messages = ['Hey!', 'How are you?', 'Thanks suXin for help :birb:']; 

app.get('/', (req, res) => {
    console.log("New request");
    var i = 0;
    res.setHeader('Content-Type', 'text/plain');

    const readable = new Readable();
    readable._read = () => {}; // Required for a readable stream

    const interval = setInterval(() => {
        readable.push(`${messages[i]}\n`);
        console.log(messages[i]);
        i++;

        if (i >= messages.length) {
        clearInterval(interval);
        readable.push(null); 
        }
    }, 1000);

    readable.pipe(res);
});

app.get("/health", (req, res) => {
    res.status(200).send({
        status: "OK"
    });
})

app.listen(3000, () => {
    console.log("Listening on port 3000");    
});

How would I fix it?

Solution:

use the PORT environment variable provided by railway instead of specifying a port
