Tailwind autocomplete stopped working in ERB files

[drale2k]

Sorry for this duplicate but i am not sure where to open this issue, in the main repo or in the ruby extension. I opened it in main but then figured since it seems to only impact ruby / ERB files, it might be an extension issue. If it's not let me know and i will close.

Summary

Tailwind autocomplete stopped working for me for 2 weeks or so. The whole ERB file is impacted - HTML inside and outside ERB tags. It does work fine when i create a .html file.

I tried both language server configs, the old and the new one

The new one according to current docs

"tailwindcss-language-server": {
      "settings": {
        "includeLanguages": {
          "html/erb": "html",
          "ruby": "html"
        },
        "experimental": {
          "classRegex": ["\\bclass:\\s*['\"]([^'\"]*)['\"]"]
        }
      }
    }

and the old one

"tailwindcss-language-server": {
      "settings": {
        "includeLanguages": {
          "erb": "html",
          "ruby": "html"
        },
        "experimental": {
          "classRegex": ["\\bclass:\\s*['\"]([^'\"]*)['\"]"]
        }
      }
    }

None of them work. The tailwind LSP server RPC log is completely empty. When i create a plain .html file it works fine and RPC messages come in.

Language mappings are currently set via initialization options (`userLanguages`). This is deprecated and will be removed in a future release. Please use the `tailwindCSS.includeLanguages` setting instead.

There is this line app/assets/tailwind/application.css] Failed to load workspace modules.. I am not sure what it means by workspace modules but as said, does not seem to impact .html files.
