Fetching Folder Object by FolderID and Changekey

[Apotrox]

Hey there!

I've tried looking through the existing issues as well as the documentation but haven't really found what i was looking for.

After exporting a Folders' ID and Changekey (with .id and .changekey), i am trying to fetch/query the Folder Object with those values again.
I have found and tried your suggestion in #1086 with the SingleFolderQuerySet and FolderID here:
folder_src = SingleFolderQuerySet(account=acc,folder=FolderId(id=undo_src[0], changekey=undo_src[1])).resolve(), however it throws a ValueError: Unsupported folder class: FolderId(id='AAMkAGVlNWJmODBiLWJkZGEtNGY5Ny1hOTk2LWJiYzA1YjVjZjVhMwAuAAAAAAAc5jkvEgsCRLJhI62C4TiPAQBuTLQ+kl9fQ7TEKh263i6XAAAAAAFjAAA=', changekey='AQAAABYAAABuTLQ+kl9fQ7TEKh263i6XAAAAAdnL')

I am kinda pulling my hair out on this one so i'd greatly appreciate some pointers!

There are various ways to do this, but the easiest os probably:

a = Account(...)
my_folder_by_id = SingleFolderQuerySet(account=a, folder=a.root).get(id='AAMkAGV...')

The changekey is only necessary if you want to be sure that the folder was not changed in any way since you collected the changekey, which is usually not relevant.
