Description

I'm using standalone nixvim template.

Minimal, Reproducible Example (MRE)

programs.nixvim = {
  plugins.lsp {
    enable = true;
    servers = {
      html = {
        enable = true;
        filetypes = [ "html" "test" ]; # this doesn't work (opened in html file and :LspInfo showed html and templ only
      };
      gopls = {
        enable = true;
        filetypes = [  "go" "test" ]; # this works
      };
    };
  };
}
