let g:indentLine_fileTypeExclude = ['coc-explorer']

let g:coc_explorer_global_presets = {
            \   'default': {
            \     'file-child-template': '[indent][icon | 1] [diagnosticError & 1][filename omitCenter 1] [linkIcon & 1][link growRight 1 omitCenter 5]'
            \   }
            \ }

I cannot jump to a file with git modification/warnings/errors any more

My config can be viewed at: https://github.com/GopherJ/cfg/tree/master/coc

I'm using the latest version of coc.nvim and I'm not reproducing the problem.
What is the result of running :verbose nmap <leader>k in the coc-explorer buffer?

[GopherJ]

@weirongxu it returns this:

n  \k           @<Plug>(coc-explorer-key-n-[leader]k)
        Last set from ~/.config/coc/extensions/node_modules/coc-explorer/autoload/coc_explorer/mappings
.vim line 13
n  \k            <Plug>(coc-diagnostic-prev-error)
        Last set from ~/.vim/init.vim line 496
Press ENTER or type command to continue

I tried again and it seems <leader>k,j,K, J is working, ;k,j is still broken, I have the following in ~/.vimrc, not sure if it's related

nmap <expr> ;k empty(get(b:, "coc_git_status", "")) ? "<Plug>(coc-git-prevconflict)" : "<Plug>(coc-git-prevchunk)"
nmap <expr> ;j empty(get(b:, "coc_git_status", "")) ? "<Plug>(coc-git-nextconflict)" : "<Plug>(coc-git-nextchunk)"
