"Language server exited" error after adding pyright + ruff

[AIrone0]

I added pyright and ruff after following the instructions here https://github.com/helix-editor/helix/wiki/Language-Server-Configurations#pyright--ruff
but each time I open a new python file I get the Language server exited message in the bottom left.

My languages.toml:

[[language]]
name = "python"
language-servers = [ "pyright", "ruff" ]

[language-server.pyright.config.python.analysis]
typeCheckingMode = "basic"

[language-server.ruff]
command = "ruff-lsp"
[language-server.ruff.config.settings]
args = ["--ignore", "E501"]

My error log:

You can safely remove the custom configuration for the ruff command because:

1. ruff-lsp is deprecated
2. ruff is already configured by Helix

Thank you!

No problem :)
