error: could not parse 'Drop' when rebasing

error: could not parse 'Drop' when rebasing

[Jarno Suni]

git version 2.43.0

$ git rebase --edit-todo
error: could not parse 'Drop'
error: invalid line 1: r Drop option --figure-soname-bumps
error: could not parse 'Drop'
error: invalid line 1: p Drop option --figure-soname-bumps
You can fix this with 'git rebase --edit-todo' and then run 'git
rebase --continue'.
Or you can abort the rebase with 'git rebase --abort'.

"Drop option --figure-soname-bumps" is the commit message.
Git doesn't seem to accept any command for the commit. First I tried command d.

Workaround:
I did `git rebase --abort`. Started new rebase, used r command for the
commit to rename it to not have "Drop" as first word. After that I can
rebase again and use d command for the commit.

It appears that the object id for the commit got deleted when the 
command was changed from "pick" to "reword" and so git does not know 
which commit this line is referring to. The commit subject is there for 
the benefit of the user not for git - after all many commits could share 
the same subject.

Best Wishes

I'm not sure that explains why the commit object id is missing. If you 
are able to reproduce this bug and show the edited todo-list with the 
drop commands and the errors produced by that todo-list that would be 
very helpful. Without that it is hard to tell what's happening here.
