I'm getting the following error E684: list index out of range: 0 when I run fzf with rg --files, and hit enter. I'm not sure how to debug this, and I've never done any vim development. How can I get more debugging information?

It happens in both neovim and vim.
This is how it looks in my .vimrc:

" FILES (This command fails)
let g:open_command = 'rg --files --hidden --follow --ignore-case --fixed-strings -g "!{.git,node_modules}"'
command! -bang -nargs=* R call fzf#vim#grep(g:open_command .shellescape(<q-args>), 1, <bang>0 ? fzf#vim#with_preview('right:50%') : fzf#vim#with_preview('right:50%:hidden', '?'), <bang>0)

" SEARCH IN FILES
let g:files_command = '
    \ rg --column --line-number --fixed-strings --ignore-case --no-ignore --hidden --follow --color "always"
    \ -g "!{.git,node_modules,build,yarn.lock,dist}/*" '

command! -bang -nargs=* Rg call fzf#vim#grep(g:files_command .shellescape(<q-args>), 1, <bang>0 ? fzf#vim#with_preview('up:60%') : fzf#vim#with_preview('right:50%', '?'), <bang>0)

I'm pretty sure it has something to do with the --files flag.
rg --files works fine in the terminal, outside vim.

neovim error:

Thanks for the amazing work on FZF

fzf#vim#grep is for file content search, e.g. rg foo, where each line prints the location of the match. rg --files only lists the file paths, and you should use it with fzf#vim#files.

Thanks @junegunn - It worked.
I wanted to overwrite my default command, so ended up with this:

command! -bang -nargs=* AllFiles call fzf#run(fzf#wrap(
    \ {'source': 'rg --files --hidden --no-ignore --follow --ignore-case'}, <bang>0 ? fzf#vim#with_preview('right:50%') : fzf#vim#with_preview('right:50%:hidden', '?'), <bang>0)

@junegunn This helped me understand how to (not) integrate the fd command, thanks!

@terkelg, I think your command missed a close parenthese at the end.

@junegunn Hi, would you please help with how to implement this command with fzf#vim#files function?
