An error on the latest neovim

I'm getting

Error executing vim.schedule lua callback: ...ite/pack/packer/start/null-ls.nvim/lua/null-ls/utils.lua:14:

when opening any file that has corresponding null-ls source. Config.

$ nvim --version
NVIM v0.7.0-dev+818-g6aeaff122
...

Is that a bug or wrong configuration?
