I am currently doing the JavaScript Simplified course on https://courses.webdevsimplified.com/ and he is teaching how to use parcel to bundle a html file. But I can’t get it to work properly.

And he says that after changing:
"scripts": { "test": "echo "Error: no test specified" && exit 1" }
to
"scripts": { "start": "parcel index.html" }
inside the package.json file, I should run npm start on the terminal, but when I do that I get returned:
Server running at http://localhost:xxxx
