Ok, here is your answer... There are no instruments in the Gov/Corp segment that are issued in Australian Cents ("AUc") and so that is why you are getting that message.

What may be less clear is how you could have known that in advance. In the DSS GUI, we do in fact not list it in the Gov/Corp Search screen's Currency List, but in the REST API, we have not externalized the ability to enumerate Currencies by segment.

Basically, there can never be any results when filtering to "AUc" but one might say that validation error response does not make that clear.

You are welcome to contact your Account Manager and submit an Enhancement Request asking for this to be made easier, but rest assured, you are not missing any search results and should simply refrain from using "AUc" in GovCorp searches; in fact, I do not believe there are any minor currency Gov/Corp instruments.

Can you please post the error you received. If you can, the entire HTTP Reply is even better. Thanks.

I am a bit confused.../Search/GetGovCorpSubGroups just returns a collection of GovCorpSubGroup entities.
