Not working with neovim null-ls

[letstakeawalk]

Hi, I installed the package using mason.nvim and black, and I followed your dotfile repo to configure null-ls. But it's not working. When I try to format a Python file cat some_file.py | blackd-client, I get an error message that says Error formatting with blackd-client: Connection refused (os error 61). Can you help me fix this problem?

After reinstalling black with brew and starting black as a service, everything is working fine as expected. Thank you for writing this package. :)
