I uploaded the application to heroku server, however I can't make it work, I don't know how to configure the environment variables that the application requires in heroku

this is my Procfile file
web: node debug.js

this is my package.json
{ "name": "Eshop", "description": "A simple and powerful Eshop solution written in Total.js / Node.js.", "version": "11.0.0", "main": "release.js", "repository": { "type": "git", "url": "https://github.com/totaljs/eshop" }, "dependencies": { "express": "^4.17.1", "paypal-express-checkout": "^1.6.3", "total.js": "^3.4.4" }, "scripts": { "start": "node debug.js", "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [ "eshop", "ecommerce" ], "author": "Peter Širka", "license": "MIT" }

this is my debug.js

`// ===================================================
// FOR DEVELOPMENT
// Total.js - framework for Node.js platform
// https://www.totaljs.com
// ===================================================
//async function main(){
// await a
//}
var options = {};
options.port = 5000;

// options.ip = '127.0.0.1';
// options.port = parseInt(process.argv[2]);
// options.config = { name: 'Total.js' };
// options.sleep = 3000;
// options.inspector = 9229;
// options.watch = ['private'];

require('total.js/debug')(options);`

this is the error I get with the heroku logs command:

2020-07-18T21:09:46.897638+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch 2020-07-18T21:09:46.916891+00:00 heroku[web.1]: Stopping process with SIGKILL 2020-07-18T21:09:46.970044+00:00 heroku[web.1]: Process exited with status 137 2020-07-18T21:09:47.009886+00:00 heroku[web.1]: State changed from starting to crashed 2020-07-19T03:08:03.606474+00:00 heroku[web.1]: State changed from crashed to starting 2020-07-19T03:08:06.885322+00:00 heroku[web.1]: Starting process with command node debug.js 2020-07-19T03:08:09.299623+00:00 app[web.1]: > DEBUG PID: 4 (v3.4.4)
