Hi,
I am currently stuck at the end of a one of my 'more useful' flows :). I'm trying to re-use information entered into a SharePoint list, including the attached files (if any) to create a document set somewhere else and then upload the attachments (if any) to that newly created document set.
All is well until the 'copy' action runs - it fails with the error "Unsupported list type for copy/move. Copy/move can only be operated in Document Library." I can confirm that the destination folder is the URL to an existing document set in a document library.

I see two possible issues, but I don't see the solution for either one:
1. Either the way my Destination Folder is construed is not recognized by Power Automate (using this URL in a browser works because of a redirect in the background) - should I generate the URL in another way? Please don't tell me I have to first fetch the ID, FolderCTID, List, RootFolder AND RecSrc 🙂
2. Or I just cannot use this copy-action and should resort to something else (HTTP POST?) - I couldn't find any online resources (the web seems filled with instructions to create or move document sets)
Thank you for any help or pointer!
