RESOLUTION:
Try using a source field of type "Attachment"
(Scope: All Attachments)?
"Attachment:
- Extract an attachment (or multiple attachments) from the named Rich Text item in each document
and/or document level attachments.
- In the ItemName field, enter the rich text item you want to extract attachments from.
If you leave the ItemName blank, then all attachments in each document will be extracted.
For further details, see the AttachmentScope section."
(You can use a field of type "Attachment Links" along with it.)
