:Lazy and E11: Invalid in command-line window

[oschrenk]

I'm trying to understand an error I am getting when working with :Lazy (in nvim 0.9.4) and vim-tmux-navigator.

Whenever Lazy is open and I am trying to navigate out of the window and jump to a neighboring tmux pane, I get

E11: Invalid in command-line window; <CR> executes, CTRL-C quits: wincm
d k

It still works but it still shows an error.
I believe it comes from here:

function! s:VimNavigate(direction)
  try
    execute 'wincmd ' . a:direction
  catch
    echohl ErrorMsg | echo 'E11: Invalid in command-line window; <CR> executes, CTRL-C quits: wincmd k' | echohl None
  endtry
endfunction

When I comment out

    echohl ErrorMsg | echo 'E11: Invalid in command-line window; <CR> executes, CTRL-C quits: wincmd k' | echohl None

I can still navigate panes without issues.

This is similar to

#67

I also get an error when trying to quit the window using :q but I am not sure if that is "caused" by the same issue, as in that case I see
