Error detected while processing function ... Vim(let):E684: list index out of range:1

[linrongbin16]

• I have fzf 0.30.0 or above
• I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• I have read through the manual page of fzf (man fzf)
• I have searched through the existing issues

Installed with packer.nvim

    use { 'junegunn/fzf', run = ":call fzf#install()", }
    use { 'junegunn/fzf.vim' }

I defined a custom command, trying to find files with fd --no-ignore --hidden:

    command! -bang -nargs=? FzfFilesNoIgnore
        \ call fzf#vim#grep('fd -tf -tl -i -u --exclude ".git" '.shellescape(<q-args>), 0, fzf#vim#with_preview(), <bang>0)

It's good to open fd and fuzzy search a file. But when enter to open the file. There's an error:

Please help me with that.

I have found two similar issues:

• https://vi.stackexchange.com/a/31016/6600
• E684: list index out of range: 0 #462

The fzf#run and fzf#wrap should solve this issue.

Finally, the correct command is:

    command! -bang -nargs=? -complete=dir UnrestrictedFiles
        \ call fzf#run(
        \   fzf#vim#with_preview(
        \     fzf#wrap({ 'source': 'fd -tf -tl -i -u --exclude ".git" '.shellescape(<q-args>) }, <bang>0)
        \   )
        \ )
