Thanks for the update @roy,
Yes, all of the objects are referenced by ID, rather than path, so it takes some work to get those IDs.
If you recently performed a sync on the folder, and sent at diagnostic, I may be able to extract the ID for that folder from there, to help out. Otherwise you should be able to use the query string (q parameter) to search for the parent folder with “name”, grab the ID from there, then query using the “parents” search parameter.
