Hydra not working well with diagnosticprevious and diagnosticnext functions of plugin Coc

[mahaaaham]

Hi,

I wrote this little hydra:

Hydra({
   color = pink,
   name = 'Coc diagnostic',
   mode = 'n',
   body = 'z',
   config = {
        hint = false,
    },
   heads = {
      { ',', ':call  CocActionAsync("diagnosticPrevious")<CR>'},
      { ';', ':call  CocActionAsync("diagnosticNext")<CR>'},
   }
})

In order to navigate between the diagnostics of the plugin Coc.
(the commands are actually the one used to define the (coc-diagnostic-prev) and (coc-diagnostic-next) command indicated in https://github.com/neoclide/coc.nvim . The aim is to jump from a diagnostic to another).

Interestingly, when I directly put the command on vim, it work perfectly. But If i try to use hydra, I need to push "enter" again in order for it to work, and this seems to only work once. To be honest, I don't really understand what is happening, but it is maybe linked to #87 ?

My informations about nvim :

NVIM v0.9.2
Build type: Release
LuaJIT 2.1.1694285958

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/usr/share/nvim"
