I was following a tutorial on YouTube of freecodecamp with the title “MERN Stack Tutorial – Book Store Project”
I am trying to run it on port 5555
I am still at the start of project just trying to check if the server is running or not
here is the link https://www.youtube.com/watch?v=-42K44A1oMA
And the problem is I am facing an issue after running the command “npm run dev” as I am getting this error: Node.js v20.12.2
[nodemon] app crashed – waiting for file changes before starting… screenshot for referenceerror screenshot

index.js code snippet

import express from "express";
import { PORT } from "./config";

const app = express();

app.listen(PORT, () => {
    console.log("App is listening to port: ${PORT}");
});

config.js code snippet

import express from "express";
import { PORT } from "./config";

const app = express();

app.listen(PORT, () => {

I have tried a lot of solutions from various sites on the internet, but still facing the issue, can anyone help me with this?
