How to reproduce the problem from neovim/Vim startup (Required!)

This is a question, not a bug report

Generate a logfile if appropriate

1. export NVIM_PYTHON_LOG_FILE=/tmp/log
2. export NVIM_PYTHON_LOG_LEVEL=DEBUG
3. nvim -u minimal.vimrc
4. some works
5. cat /tmp/log_{PID}

Screenshot (if possible)

Upload the log file

Both nvim-lsp and coc-vimlsp use the same language server (https://github.com/iamcco/vim-language-server)

Q: I want to use floating preview window feature with deoplete.

A: Please install float-preview.nvim plugin.
https://github.com/ncm2/float-preview.nvim

[Shougo]

I have tested vim-language-server and it does not include detailed information.

[Shougo]

I think to use this is better.

Note: float-preview.nvim does not support completionItem/resolve behavior. So the problem exists.
