There was a failure executing the response(receive) pipeline: “Microsoft.BizTalk.DefaultPipelines.XMLReceive, Microsoft.BizTalk.DefaultPipelines, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35″ Source: “XML disassembler” Send Port: “FlightStatsAPITest_1.0.0.0_FlightStatsAPITest.DemoFlightStats_FlightStats_271205145d00a26b” URI: “” Reason: Finding the document specification by message type “” failed. Verify the schema deployed properly. 

Solution: make sure don’t have the .wsdl on the URL of the URL that you type in SEND port.
This was a “dumb mistake” I made.  I pasted the .wsdl URL instead of the service URL into the website to be called by the send port.  To the response message was coming back to my orchestration, but didn’t have a matching schema.
