problem with queryContext from ContextBroker

[koff-fkd]

I want to get a contextdata from an IoT Broker via an ContextBroker with NGSI10:queryContext.
IoTBroker can get the contextdata from device,
but ContextBroker can't get the contextdata from IoTBroker.
the ContextBroker give me this error.

Following, the portion of interest of the ContextBroker log:
