Error: Can't resolve 'child_process' in 'node_modules/worker-farm/lib'` #9263

Bug report

Describe the bug

I have an application with three pages. The app works fine but when I access the third page, I get an error with Module not found: Can't resolve 'child_process' in '/workspace/observe.dev/node_modules/worker-farm/lib'
The bug showed up even with no change in the source code from my part! I have tried a clean install but did not work.

To Reproduce

I do not know how to reproduce as it happens all unexpectedly.

Expected behavior

To work as it did before, just render the page!

It's not possible to reproduce this issue without a clear and concise reproduction as asked for in the issue template. Please provide one so that we can have a look.

Alaboudi1 · 2019-10-31T13:29:48Z

Hi, thanks for the prompt response! here is the source code I am working on
https://github.com/Alaboudi1/observe.dev
https://codesandbox.io/s/github/Alaboudi1/observe.dev/tree/master/?fontsize=14
just install it and then run the app, open localhost:3000 and then navigate as follows.

And then the error happens!

Alaboudi1 · 2019-10-31T14:27:41Z

Alright, I found the cause of this error. It is the auto import in VS code. It auto imported import { debug } from "webpack"; when I inserted a debug statement, which causes this supper confusing error message.
