Note: I read through the other similar questions (here and others), but they are all about earlier versions of webpack and babel and do not solve the following issue.
This is serving just fine, but when I run npm run build I'm getting the following error. How do I solve this? (And how do I get better errors than this?, the log is just as bad).

Does your code editor show any errors when you open the incriminated file? Have you tried deleting your node_modules and reinstalling them? – Altareos Commented Jul 17, 2021 at 18:08
- @Altareos node v16.5.0 , no errors in the code editor. Yes I've tried deleting the node_modules folder and reinstalling. I'm getting the same error. – Agent Zebra Commented Jul 17, 2021 at 18:15

Reset to default 2Just remove the styles import
import "./style.css"
Webpack speaks JavaScript, not css, if you want it to learn it you need to create a webpack config file and use the proper loader to handle css
