Hey @alaa bebar

Please review your task history thoroughly. The Attachment Links have been mapped in the Iterator action step from the Email Parser's trigger response. However, in some instances, no attachment was available in the received emails, causing the mapped field of Attachment Link to not appear, which in turn caused the Iterator action step and subsequent actions to fail.
