Knowledge Categories Ancestors - Guest session

[Jan_Heinonen]

In the Knowledge API for guest session there's an option to expand described in the API Toolkit.

GET
/api/v2/knowledge/guest/sessions/{sessionId}/categories?expand=Ancestors

But the "Ancestors" doesn't seem to anything.

What is this parameter supposed to do?
From the description I'm think it should include all "parents" of an category, but I get the same result with/without the parameter.

I tested this with

get
/api/v2/knowledge/knowledgebases/{knowledgeBaseId}/categories

and there I get the result I expected with "expand=Ancestors" so I guess it just doesn't work in the Guest Session API.
