Hi Brad,
I've been using the underlying language server for this plugin using vim-lsc (see raised issue here: natebosch/vim-lsc#251)
There is a call to console.log(t.configDependencies) that is causing a [] to be prepended to the message header being sent. This prevents tailwindcss-language-server being used.
It'd be good to understand why that log is there, if it's not useful could you remove it from the npm library?
Best,
Mike
