@JorTurFer btw you can enable pre-commit locally, so you catch these kind of issues before commiting the actual code.

I got it... but disabled because the tools are only installed inside the dev container, I should install them also in the host. Probably when my new computer arrives, I'll do something more reliable xD (usually I run it manually, but sometimes I forget it)

Anyway, thanks for the suggestion ❤️
