Hi @alee, I noticed that the commit is coming from @carpentries-bot and I wonder if you might accidentally be experiencing this issue: https://github.com/carpentries/sandpaper/issues/449

You might want to check that you have sandpaper >= 0.12.3 and then check and remove the user and email from this repository's .git/config

good catch! I was mucking around with a containerized version of this some time ago and it must have modified .git/config. I'll close and resubmit
