Error running vim.ui.select in the fzf_lua backend the first time since nvim startup

[Penaz91]

Describe the bug The first time I use vim.ui.select after starting Nvim, I get an error similar to the following:

Error executing vim.schedule lua callback: ...cker/start/dressing.nvim/lua/dressing/select/fzf_lua.lua:30: attempt to call a nil value                                              
stack traceback:
        ...cker/start/dressing.nvim/lua/dressing/select/fzf_lua.lua:30: in function 'select'
        .../packer/start/dressing.nvim/lua/dressing/select/init.lua:63: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

This was triggered by using the :lua vim.ui.select({1,2,3}, {}, function(opt)end) command. Running the command again will work correctly

System information

• OS: Artix Linux
• Neovim version: 0.7.2
• Is this related to a specific vim.ui.select backend? If so, which one? Fzf_lua
• Dressing config: Default configuration

To Reproduce Steps to reproduce the behavior:

1. Start Nvim
2. Use the following command :lua vim.ui.select({1,2,3}, {}, function(opt)end)
3. Dressing crashes
4. If you use the same command again, the command goes through correctly

Additional context I'm using the following lua plugin related to FZF:

Merged @stevearc’s PR, apologize for the mess.

@ibhagwan no worries! Bugs happen :)

@ibhagwan no worries! Bugs happen :)

I didn’t know anyone used fzf_wrap like this (directly by ref from require'fzf-lua'), I guess this was written before the introduction of the fzf_exec API which would be the better (and clearer way) to write this.

[ibhagwan]

Let me know if you wish, I can submit a PR to convert the current fzf_wrap code to fzf_exec.

[stevearc]

Would love a PR to convert it to the best-practice API!

Also took the liberty to improve upon the item number extraction using a lua regex :-)

Updated both fzf-lua and dressing to the latest commit, everything seems to be working perfectly.

It's great seeing such tight cooperation between different repository owners.

Thank you for everything, feel free to close!
