I appreciate you pointing out my mistake. That wasn't clear from the documentation I referred to [1] (when I performed the operation, I created a queue from the inventory report and performed delete requests popping the items off the queue), and I've let our TAM know the documentation I referred to needs to be improved to reflect that DeleteObject or DeleteObjects operations with a batch job aren't currently supported.

[1] "Specify the operation that you want S3 Batch Operations to run against the objects in the manifest. Each operation type accepts parameters that are specific to that operation. This enables you to perform the same tasks as if you performed the operation one-by-one on each object."
