Null Response From JsonServiceClient

In production, we are seeing an occasional Object reference not set... exception (say one in a few thousand) in our custom wrapped JsonServiceClient.Get() call, that appears to be caused (not confirmed yet) by receiving a null response from a ServiceStack service GET request.

Is receiving a null response from a ServiceStack service call even possible?

Maybe we are screwing up something in our JsonServiceClient wrapper since we are doing custom client caching there using the ResultsFilter and ResultsFilterResponse, and sometimes those properties are assigned null? Possible cause?

Have no idea, need a repro to be able to identify the issue.

ServiceStack Services can return an empty Response Body if they want, but I doubt that’s the issue here.
