Using FZF from neovim

[pattydaone]

I've been trying recently to use fzf "as is" in neovim. That is, with this repo and not fzf.vim or fzf.lua. The readme file seems to imply that it works in neovim. But I'm encountering a severe problem. Fzf doesn't seem to be receiving the funcref I set in g:fzf_action which causes it to error. The current state of my config looks something like:

vim.cmd([[
	function ChangeCWD(lines)
		exe "e" a:lines[0]
		cd %:h
	endfunction
]])

vim.g.fzf_colors = {
	 ...
}

vim.g.fzf_action = { ['enter'] = vim.fn['function']('ChangeCWD') }

vim.api.nvim_create_user_command('L', 
	function()
		vim.fn['fzf#run'](
			vim.fn['fzf#wrap'](
				{ ['source']='find . -maxdepth 5', 
				  ['options']='--preview="head"' }
			)
		)
	end,
	{ nargs = 0 }
)

Whenever I attempt to use the L command and 'enter', I'm met with Vim(call):E718: Funcref required. I'm supposing that the plugin isn't receiving the function reference somehow ? I don't know. I do know, however, that setting the variable in this way is ok. Just above, with vim.g.fzf_colors, I set the variable using this lua syntax and fzf interprets it same as it would vimscript.

I would like to note, I started on vim, and configured it in vimscript, which definitely works. The very first thing I did was copy-paste my vimscript into a vim.cmd([[]]) call; it doesn't work from there either. I also tried it with a completely untouched init.lua file except for the fzf configuration, no good. On the other hand, following neovims provided "from vim to neovim" setup instructions, everything works as it should.

Other things I tried include defining the function in lua and giving fzf_action a reference to the lua function, and moving my ChangeCWD function to a separate .vim file and sourcing it into my init.lua. Again, no good.

Another note is that everything else works as expected with fzf. If I set sink to 'e' or 'tabe' it works fine.

I'm kind of at a loss for what the problem is. I know that I could just use fzf.lua, and I very well might, but I'd really like to know why this isn't working. If anyone has any ideas, that'd be really appreciated.
