I already replied to the bot message before I saw this thread.

The problem is the base-commit: in the cover letter. I'm guessing that
you did `b4 prep --edit-deps` at some point and pointed it to something
other than the actual tree you are working from.

That would explain why the test passes locally but not with the bot.
