Please upload your init.vim.
It seems you have called lspconfig before loading.

It is invalid config. Because it does not use dein functions.
Why you have created issue without dein functions?

[Shougo]

For example,

call plug#begin('~/.nvim/plugged')

Plug 'vim-airline/vim-airline'
Plug 'vim-airline/vim-airline-themes'
Plug 'tomasiser/vim-code-dark'
Plug 'neoclide/coc.nvim', {'branch': 'release'}
"Plug 'scrooloose/nerdcommenter'
Plug 'scrooloose/nerdtree'
Plug 'ryanoasis/vim-devicons'

call plug#end()

"""""""""""""""""""""

After call plug#end(), you can call plugins functions. Because call dein#end() loads plugins.
It is vim-plug's feature.

For dein.vim, call dein#begin()/call dein#end() block is needed.

[Blayung]

I didn't know, that it had meaning, but I had my lua code in between call plug#begin() and call plug#end().

[Blayung]

Wait... I didn't put this issue where I wanted! It was supposed to be in neovim/nvim-lspconfig! Sorry!

[Shougo]

What plugin manager do you use?
It is not plugin problem.
It is just your mis configuration.

[Blayung]

Yep, but I didn't know about that + I use vim plug.
