Deplopyment Error on Vercel: Cannot find module &#…

I have a package.json script like:

{
 "export": "next export",
 "build": "next build && npm run export && npm run build:rss",
 "build:rss": "node ./.next/server/scripts/build-rss.js",
 "start": "next start",
}

It has build:rss which points to ./.next/server/scripts/build-rss.js but it cannot find it on Vercel. How do I point it correctly on Vercel? I get the following error & cannot deploy my site:

> node ./.next/server/scripts/build-rss.js
15:14:05.786 internal/modules/cjs/loader.js:968
15:14:05.786 throw err;
15:14:05.786 ^

I tried asking Vercel support but they said:

I recommend doing something like this → https://github.com/pacocoursey/paco/blob/master/package.json. I’m afraid we do not provide complete code-level support for users on the Hobby plan.

Not sure the link is relevant 🙁

I had to change server to serverless to make it work on Vercel 🙂
