process.env.PORT from dotenv causes EACESS: permission denied error in node

Question

So I just installed dotenv in my project and I am requiring it with this code:

require("dotenv").config();

And then using my variables like so:

app.listen(process.env.PORT, () => {
  console.log(`Listening on ${process.env.ENDPOINT}:${process.env.PORT}`);
});

In .env:

ENDPOINT = "127.0.0.1";
PORT = 5000;

Code works just fine if I add the variables as constants within my js file, but when I try to access the variables through process.env I get:

events.js:291 throw er; // Unhandled 'error' event ^

Error: listen EACCES: permission denied 5000; at Server.setupListenHandle [as _listen2] (net.js:1299:21) at listenInCluster (net.js:1364:12) at Server.listen (net.js:1461:5) at Function.listen (C:\Users\Darkbound\Desktop\TouchScreenProject\SmartFactory\server\node_modules\express\lib\application.js:618:24) at Object.

errno: -4092, syscall: 'listen', address: '5000;', port: -1 }

I have tried using other ports, I get the same error on all ports, I have tried 3000, 3010, 5000 etc.

If the other variable, ENDPOINT is accesses without problems, so if I do:

const PORT = 5000;

app.listen(PORT, () => {
  console.log(`Listening on ${process.env.ENDPOINT}:${PORT}`);
});

This works.

EDIT SOLVED: I found the issue, as usual, right after I ask the question. The issue is that I have ; at the end of each variable in the .env file. this happened because I copy/pasted the variable from my javascript and I only deleted the const but forgot about ;
