Can't get subcollections in folder

[KarenXuan]

I want to get subcollections in a special folder, I have folder id, and I get folder by session.file_by_id, I can see the output as: "Root Folder Test, https://drive.google.com/drive/folders/0B1FLMKfTaZZ4sXd5TDdEO99W31M, class: GoogleDrive::Collection" But when I call root_folder.subcollections, it return an empty array, and also I really see a folder called "fastlane" in the folder "test", but I call file_by_title("fastlane") or subcollection_by_title(fastlane), they all return nil. So how can I get the subfolder?

By the way, my test folder is on the team driver, but I think since I can get folder by id, why I can't get folder by title?

Having the same problem. It seems to be a Shared Drive issue only.
