Seems like a catapult or infra bug.

I think the file deletion error might be a red herring; it's been going on for awhile in other tests and not causing them to fail: https://github.com/catapult-project/catapult/issues/3398
So maybe the traceback right before that message is important? Still looks like an infra issue tho
