The Content-Type depends on whether the job output is an archive or a vault inventory. For archive data, the Content-Type is
            application/octet-stream. For vault inventory, if you requested CSV format when you initiated the job, the Content-Type is text/csv.
            Otherwise, by default, vault inventory is returned as JSON, and the Content-Type is application/json.
