javascript - TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined raised when starting react app

Question

I'm working on a project in React and ran into a problem that has me stumped.

Whenever I run yarn start I get this error:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

I have no idea why this is happening, if anyone has experienced this I would be grateful.

To fix this issue simply upgrade react-scripts package (check latest version with npm info react-scripts version):

1. Replace in your package.json "react-scripts": "^3.x.x" with "react-scripts": "^3.4.1" (or the latest available version)
2. (optional for some) Delete your node_modules folder
3. Run npm install or yarn install

Some people reported that this issue was caused by running npm audit fix (avoid it!).
