Null-ls is not registering any sources

FAQ

Issues

• I have checked existing issues and there are no issues with the same problem.

Neovim Version

0.9.1

Dev Version?

• I am using a stable Neovim release version, or if I am using a dev version of Neovim I have confirmed that my issue is reproducible on a stable version.

Operating System

Linux - Ubuntu 20.04 (WSL

Minimal Config

-- to the minimal config just add stylua
local null_ls = require("null-ls")

null_ls.setup({
    sources = {
        null_ls.builtins.formatting.stylua,
    },
})

-- and in packer Mason / lsp

Steps to Reproduce

1. Deleted my previous nvim config files (where I installed plenty of formatters)
2. Plugged new minimal nvim config files
3. :PackerSync
4. :echo executable('stylua')
5. :NullLsInfo

Reproducibility Check

• I confirm that my minimal config is based on the minimal_init.lua template and that my issue is reproducible by running nvim --clean -u minimal_init.lua and following the steps above.

Expected Behavior

Null-ls should be able to recognize the sources available 😄

Actual Behavior

While running NullLsInfo it says:
* Note: current buffer has no sources attached

Stylua (and other formatter, i.e. like black) is present on Mason and it is executable both outside and inside of nvim, since
:echo executable('stylua') returns 1

btw, thanks to @jose-elias-alvarez for such an amazing job! 😏

I added stylua and it looks like it is working

and from my null-ls config

I also diabled formatting in lua_ls settings
