How do I `git rebase -i` and prevent “You asked to amend the most recent commit, but doing so would make it empty.”?

Question

I want to run a git rebase -i some-hash.

When I run it, I get the error:

You asked to amend the most recent commit, but doing so

Answer 1

Seems like running:

git commit --allow-empty
git rebase --continue

Creates 2 squashed commits, instead of one. Running git rebase -i some-hash allows me to squash the 2 new commits into one.
