Reproduction steps

1. Create a toy Lua project with the following .luarc.json:

   {
     "$schema": "https://raw.githubusercontent.com/sumneko/vscode-lua/master/setting/schema.json",
     "Lua.diagnostics.globals": [
       "vim"
     ],
     "runtime.version": "LuaJIT",
     "workspace": {
       "checkThirdParty": false,
       "library": [
           "/usr/share/nvim/runtime",
       ]
     },
     "diagnostics.libraryFiles": "Disable"
   }
   

2. Run lua-language-server --doc=. --doc_out_path=/home/user/desktop/
3. Now delete the /usr/share/nvim/runtime line and retry. Everything works again!
