I am using the recently published for preview Office 365 Unified Web APIs. In general they work, but at least one of the API endpoints is either not working, or it is not documented properly.
For instance, the following GET request returns my manager: https://graph.microsoft.com/beta/me/manager
But, calling this URL https://graph.microsoft.com/beta/me/WorkingWith returns a 400 Bad Request, even though it should return the colleagues that I am most collaborating with.
Preview features and Graph queries are enabled both in Office 365 and SharePoint Online settings.
Is anyone experiencing a similar issue? O ris there someone from MS to anser?
