Error for coc-yaml

[YangKian]

I install the coc-yaml extention, but when I want to add any field about yaml, such as yaml.trace.server , I get the following error:

The CocInfo is:

vim version: NVIM v0.4.3 node version: v12.15.0 coc.nvim version: 0.0.77-b7a597f7ae term: xterm-256color platform: linux

and my CocConfig file is:

try to see a CocOpenLog:

Have tried to uninstall the coc-yaml, uninstall coc-neovim and reinstall them, but none of these worked. So anything I can do to fix this?

@YangKian You have to set yaml~ settings outside languageserver block. I made the same mistake. I don't remember where did I copied it. Someone obviously post the wrong sample configuration.

@aca You're right, it works for me now (:з」∠) Thanks a lot！
