Problem with webpack 4 : Object prototype may only be an Object or null: undefined

[mebest100]

I build react on webpack 4.44.2, but when compile complete and it will report Object prototype may only be an Object or null: undefined from Browser console as follow screenshot:

It seems connected to graceful-fs, but I don't know how it come. Could anybody told the root cause about the errors. Thx!

(graceful-fs.js:96) at Object../node_modules/node-localstorage/node_modules/graceful-fs/graceful-fs.js (graceful-fs.js:429)

See #216.

Yes, I solved this problem, the root cause comes from vscode, it insert useless code and cause mentioned error. Hence you just search by keywords 'from webpack' , and delete it when found, then everything is ok

Having the same issue with Laravel-mix v 6 which has this as a dependency. I read 216 but am uncertain how to identify a package which "is attempting to run in the browser but should only run on node". Any help would be greatly appreciated

Here is my dependency tree:

Another message for the next person who finds this - I don't know why the issue pointed to graceful-fs but somebody - whether VSCode or mix or a misttype on my part that autocompleted - added an import to one of my files that was causing the issue

import { find } from 'laravel-mix/src/File'

I encountered the exactly same problem, the whole project can be found here

If I use the following version, everything is fine. "svelte-language-server": "^0.13.9"

If I upgrade it, gracefulFs fails with the exactly same error "svelte-language-server": "^0.14.0",

I am facing same issue in my nuxt project. The nuxt mode is spa.

version v4.2.5 or higher versions may cause this error.
