Hello there :)
I m daily using attachment in copilot studio like in teams. I know how to use the Activity.Attachment with loop in preview or using First() to get content :)
My problem is in the new deploy to SharePoint to replace the agent created by user in sharePoint. I m not speaking about a copilot create by a user and customize in studio. I speak about the new feature to deploy directly from studio, a complet agent with all feature :)
It work very well, i have test 15 HR scenario with it, but one is stuck :
The "attachment" button immediatly send the content to the chat AND the Activity.Attachment is empty BUT the channelData contain the file (see image) but if i try to get it directly "old school way" with .OrginalAttachments; it's empty too.
To complete : this use case work 100% in the studio or in teams. It only "problem" is here in the new sharepoint expérience.
Some one know a tricks or dark magic to help ? (don't care about the french, it's texte for end user, the real things are in english below)
