The message with Action 'GetCompanyIDs' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This
may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding including security requirements. For example, Message, Transport, None.
