Hi,

After recent upgrade, I've encontered below error running nix fmt

treefmt: error: failed to generate change set: failed to open git index: invalid checksum

Any idea what might caused this and how to troubleshoot this case?

My nixos is public here, so you may be as well reproduce it by running nix fmt on it btw.

Thanks!

I'm finishing up some changes to the docs before releasing what's currently on main. I made many improvements, including moving away from go-git and shelling out to git instead. I suspect this would resolve your problem.
