Netlify Run build won't work. because of 'Unknown Word'

Question

Pretty self explanatory. Netlify won't build react app. Previous versions build fine. npm start works fine locally

I get similar results in Vscode running npm run build

Answer 1

Turns out it had something to do with a key I put in tailwind.config.js as suggested by the tailwind docs:

I just had to remove the important: true, key and use the ! modifier inline

e.g. className="!bg-green-500" Not sure why it wouldn't build with it. I updated postcss and tailwind just to make sure, but only removing it worked. Could someone who understands explain this.
