Invalid Data Item Type Event (ProtocolError)
The eMessage Connector drops any Data Item message that has an invalid type and sends an event to the Connection Server Hub. This event is called ProtocolError. It provides the details of the data item message, including the name of the Thing and a map of the names of the data items to their types that are invalid. In addition, refer to the Data Shape that defines this event for the Connection Services Extension, CXSEvent.ProtocolError .
