unhandled method textDocument/*

[derekstavis]

Hey, thanks for this package!! 👍

I have been trying to setup this language server with my neovim but I couldn't find a way to make it work.

Whenever I try to issue a command to it I get this unhandled method textDocument/*, where * is the command name. Here is my neovim setup:

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'do': 'bash install.sh',
    \ }

set hidden

let nodejs_prefix = systemlist('npm config get prefix')[0]

let g:LanguageClient_serverCommands = {
    \ 'css': [nodejs_prefix . '/bin/css-languageserver', '--stdio'],
    \ 'javascript': [nodejs_prefix . '/bin/js-langserver', '--stdio'],
    \ 'javascript.jsx': [nodejs_prefix . '/bin/js-langserver', '--stdio'],
    \ }

" Automatically start language servers.
let g:LanguageClient_autoStart = 1

nnoremap <silent> <leader>hv :call LanguageClient#textDocument_hover()<CR>
nnoremap <silent> <leader>gt :call LanguageClient#textDocument_definition()<CR>
nnoremap <silent> <leader>rn :call LanguageClient#textDocument_rename()<CR>

I have double checked and the langserver is running:

Is there something I'm doing the wrong way in here?

I'm running into this too after setting up emacs + lsp-mode. Further, I'm seeing an earlier debug message reported, as marked below with (**):

Turning on magit-auto-revert-mode...done
For information about GNU Emacs and the GNU system, type C-h C-a.
(**)Error from the Language Server: Request initialize failed with message: Cannot convert undefined or null to object (Internal Error)
File mode specification error: (lsp-empty-response-error initialize)
Error from the Language Server: Unhandled method textDocument/hover (Method not Found) [5 times]
mwheel-scroll: Beginning of buffer
Error from the Language Server: Unhandled method textDocument/hover (Method not Found) [2 times]

Unfortunately, I don't have any more information about WHAT is null or undefined.

This is a shame, as there's no real good alternative to this project for lsp for typescript-less JS development at the moment. I certainly hope we can resolve this!

If it helps I am happy to highlight the relevant bits of my emacs config. It looks like both the standard project setup instructions and @derekstavis are doing much the same thing I have to do, but in VimL rather than elisp so I'm not sure it will help the issue. If you want them, just ask.

This js lang server just doesn't work at all. None of unhandled method textDocument/* work with this nvim config:

call plug#begin('~/.config/nvim/plugged')
Plug 'autozimu/LanguageClient-neovim', {
      \ 'branch': 'next',
      \ 'do': 'bash install.sh',
      \ }
call plug#end()

let g:LanguageClient_serverCommands = {
      \ 'ruby': ['solargraph', 'stdio'],
      \ 'javascript': ['js-langserver', '--stdio'],
      \ 'javascript.jsx': ['js-langserver', '--stdio'],
      \ }
nnoremap <F5> :call LanguageClient_contextMenu()<CR>
nnoremap <silent> K :call LanguageClient#textDocument_hover()<CR>
nnoremap <silent> gd :call LanguageClient#textDocument_definition()<CR>
nnoremap <silent> <F2> :call LanguageClient#textDocument_rename()<CR>

Hey guys,

I have spent quite some time on this today trying to make it work, and I finally made it! I have already created a PR to tweak the ESLint integration, and soon will create a new one to fix the integration with Tern.

If you want to play around with my work, I pushed all my changes to my 'dev' branch -- https://github.com/iamFIREcracker/js-langserver/tree/dev

Let me know if that fixes some of the issues you were having.

Ciao,
Matteo

because GitHub notifications are usually so bloated that no one reads them 😂
