I encountered a similar problem 🤔 I'm using Spacemacs, and after upgrading the package, I started getting this error in lsp-log.

Downgrading to 0.0.4 and reverting the commit fixes to me too.

Thanks @hirotaka

hmm, @tailwindcss/language-server 0.0.5 works fine for me. is there anything special about your tailwind config? can you try (setq lsp-tailwindcss-experimental-class-regex nil)?

[hirotaka]

I think this is due to @tailwindcss/language-server update from 0.0.4 to 0.0.5. lsp-tailwindcss's fix is not relevant. I have created a PR(#31), please check it out!

This is my first LISP programming, so please let me know if I'm missing anything😉

I'm also running into this error with @tailwindcss/language-server version 0.0.7 (latest version) and the latest version of lsp-tailwindcss. For me, the issue is resolved if I simply comment out this line https://github.com/merrickluo/lsp-tailwindcss/blob/master/lsp-tailwindcss.el#L221. I'm not sure what the correct fix is, so I'll just modify lsp-client-settings in my .emacs.d for now but figured I'd chime in that there still seems to be an issue.
