Handle empty BBM directory
On the gitlab-org/gitlab side I plan to add an empty directory to signify that no batches were processed. This is implemented here: gitlab-org/gitlab!216029 (comment 2946445621)
This MR will need to be merged first because the empty batch folder causes an error now.
I should note, this is basically, pre-work to complete the issue, and it does not add a message to the comment just yet.
