Error: true is not a PostCSS plugin

[gnc11]

Hello.
Immediately after starting the dev server, I get the following errors -

ready - started server on http://localhost:3000
error - ./styles/index.css (./node_modules/css-loader/dist/cjs.js??ref--5-oneOf-6-1!./node_modules/next/dist/compiled/postcss-loader??__nextjs_postcss!./styles/index.css)
Error: true is not a PostCSS plugin

When you hit http://localhost:3000, you get an internal sever error with the following messages on the Terminal console -

event - build page: /next/dist/pages/_error
wait - compiling...
error - ./styles/index.css (./node_modules/css-loader/dist/cjs.js??ref--5-oneOf-6-1!./node_modules/next/dist/compiled/postcss-loader??__nextjs_postcss!./styles/index.css)
Error: true is not a PostCSS plugin
Error: Cannot find module '/Users/***/dev/js/corp-strapi-next/frontend/.next/build-manifest.json'

Any ideas on what the issue could be? Thank you.

Hi @gnc11 I just a did a fresh install with no issues. But I found this issue: vercel/next.js#17236.

I think this error is related to the Tailwind install: https://tailwindcss.com/docs/guides/nextjs using next v9

Have you upgraded/changed any of the dependencies?

I will keep looking, but in the meantime please let me know if either of these resources help you.
