I am doing a funny thing where I do git -C .git/modules/morx push fleem:fleem. This is failing in the case where I have a sparse checkout and the worktree directory "morx" (which is where .git/modules/morx/config's core.worktree points) doesn't exist.
I don't know why git push cares about the worktree -- it'll happily work in a bare repo with no worktree at all, or if the worktree is an unrelated git repo or whatever. I can work around it, but if there's a bug, I think we should fix it.
