A reproduction is required when filing an issue — any issue opened without a reproduction will be closed and you'll be asked to create a new issue that includes a reproduction. We're a small team and we can't keep up with the volume of issues we receive if we need to reproduce each issue from scratch ourselves.

Describe your issue

Well, it occurs when I try to make a production build of Nuxt npm run build, and during the build, i get warnings saying

WARN [plugin @tailwindcss/vite:generate:build] Sourcemap is likely to be incorrect: a plugin (@tailwindcss/vite:generate:build) was used to transform files, but didn't generate a sourcemap for the transformation. Consult the plugin documentation for help

Hey! Please include a reproduction. Could this transform step be run on a JS file? For CSS source maps, we're working on this but it's not added yet: #17775

Going to close this as a duplicate of #13694 for now but if this is indeed related to some JS files please file a new issue and attach a reproduction.
