Describe the bug

I often get these error messages when trying to use go to definition in a rust project.

Environment

Minimal vimrc content:

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

let g:LanguageClient_serverCommands = {
\ 'rust': ['rust-analyzer'],
\ }
autocmd BufEnter *.rs map <C-\> :tab call LanguageClient#textDocument_definition({'gotoCmd': 'tab drop'})<CR>

Can you share some more of the log? Also, have you tried updating rust-analyzer? I found a similar issue a few days ago but it was a specific commit that was broken and was fixed on the nightly release of the next day.
