With a command similar to
git checkout -b a7e4767 new-branch
git push origin new-branch
I get the following error
remote: ERROR: In commit a7e4767a80e9b0730c8708973918c990af308a45
remote: ERROR: committer email address someone.else@xyz.com

All my search turns up suggestions for amending the commit, but I don't think I want to amend that old commit.
