I have been seeing containers without any artefacts with jira 'on poll'. After comparison against those successfully ingested and failed, it appears to be caused by attachment(s) on the jira tickets. If all attachments are removed from the tickets, then the ingestion would succeed.
This is seen for failures using manual poll.
