How can be fixed react-scripts build error?

Question

I'm trying to build react-application(create-app-react based) for production using react-scripts, but I'm getting error on npm run build:

Creating an optimized production build...Completed in 69ms
/var/www/html/test_project/node_modules/react-scripts/scripts/build.js:19
  throw err;
  ^

    at Process.ChildProcess._handle.onexit (internal/child_process.js:285:12) {
  code: null,
  signal: 'SIGKILL'

I'm using node-js v14.19.3 and npm 8.12.1

--verbose mode didnt provide any useful details in logs. Maybe somebody had such cases. How this error can be fixed?

@MarkHayward hi Mark. yes. I increased swap size on server and it works fine. I suppose, that such errors usually refer to lack of server resources. — Sam Fisher

But nobody knows how to get better errors out of react-scripts build? My error is completely different and I don't even know which stage of build is causing it. It seems to be related to an scss file but complains about Array.forEach 🤷 — mjaggard

Hitting the same problem currently

The problem is a lack of memory. That results in undefined behavour of fork-ts-checker-webpack-plugin. Here in the related discussion they mention memory limit for npm.

@Keavon Did you try increase the memory limit in the config?

That just made me to check that. The propblem is my virtual server's having 1Gb of operating memory. This is just not enought for running build.

You may check your memory consumption using top
