"npm run build" works on my machine, but not on the server

[rvyh]

"npm run build" works on my machine, a macbook with Node v12.18.3 and npm 6.14.8.

The server is running Ubuntu 20.04.1 LTS, [email protected] and [email protected].

The process gets stuck, this is the output:

info  - Loaded env from /root/project/.env.local
info  - Using webpack 5. Reason: no next.config.js https://nextjs.org/docs/messages/webpack5
info  - Checking validity of types  
info  - Creating an optimized production build .Killed
npm ERR! code ELIFECYCLE
npm ERR! errno 137
npm ERR! [email protected] build: `next build`
npm ERR! Exit status 137
npm ERR! 
npm ERR! Failed at the [email protected] build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2021-06-07T23_03_23_256Z-debug.log

The log from the last line above doesn't include anything new.

The biggest change from last time it worked is a call to a MongoDB on Atlas (cloud) for which I store some constants at .env.local

As said locally on my machine everything works fine, "npm run dev" loads the project and "npm run build" throws no errors.
