Git sync plugin cannot find git

Hi,

I have a problem with git-sync plugin. It cannot find git (no matter what I choose in Git Binary Path).

I’ve checked location of git on my server (it’s /usr/bin/git) but wizard still says, that I don’t have git.

My grav is hosted on docker (and for the sake of debugging I installed git manually inside the container, but that didn’t solved my problem).

Any ideas what I do wrong?
