Asking support for latest status of QueryMessage & Usage Control implementations

[skante93]

I have been searching for answers about two questions lately.

QueryMessage support

I tried the POST /api/ids/query endpoint of the connector as per the swagger UI, however I was let to believe that the QueryMessage is currently not supported. The exact error message was:

Received unexpected response message. [response=({reason=https://w3id.org/idsa/code/MESSAGE_TYPE_NOT_SUPPORTED, payload=No handler for provided message type was found!, type=class de.fraunhofer.iais.eis.RejectionMessageImpl})]

Therefore I was wondering if the message is not supported or perhaps am I using the wrong endpoint?

Usage Control

What is the current status of usage control implementation in the Dataspace connector, more specifically, the policies currently supported?
Last time I checked, you could only declare your permissions with a "USE" policy, is that still the case?

Any help would be greatly appreciated!
