Email attachment lookup causing workflow to suspend

Hi all,

I've got a workflow on a list, which triggers manually. The workflow has one action which emails a user withing the O365 tenant, with a quick message and the attachment that is on the list item. Here's my situation and issue:

  • I've got it configured properly, using External email land attachment service.
  • If I use a hard-coded, relative path the attachment sends correctly.
  • If I use Advanced Lookup, and find {Current Item:Attachments} the workflow is Suspended
  • If I attempt to display {Current Item:Attachements} in the body to trace the Attachments url, the workflow is Suspended.
  • The attachment (a PDF file) on this item is the same one that works when I use the hard coded relative path, but obviously I don't want this hard-coded so it will send the attachment from each list item it's run on.


Any thoughts on why it's suspending using the Lookup? I'm using the dropdowns to configure, so it is the correct item list column value.


Here's the suspended error in detail:
