Does this error mean that node modules cant be found? - node.js

Question

I think I've seen this error on my local computer when I'm missing a module, but I am trying to start my code with pm2. Is that what the error is seen here?

Answer 1

It says it doesn't know how to "start" your app, as it's not in home/user/website/index.js
You need to edit your package.json and see which is the start command and move your files accordingly (or edit, whichever is more convenient)
