There was a failure executing the receive pipeline: Microsoft.BizTalk.DefaultPipelines… failed to load. Verify the schema for this document specification is deployed and is in the Global Assembly Cache

Sometimes, when we try to test our Visual Studio BizTalk Server solution that we deploy in the BizTalk Server environment, we get the following error message:

There was a failure executing the receive pipeline: Microsoft.BizTalk.DefaultPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″ Source: “XML disassembler” Receive Port: “Port_Name” URI: Reason: The document specification <Schema_Name> from assembly <Schema_Name, Version=1.0.0.0, Culture=neutral, PublicKeyToken=…> failed to load. Verify the schema for this document specification is deployed and is in the Global Assembly Cache.

Solution

This can error may happen for several reasons:

  • or the DLL is not deployed in the environment;
  • or for some reason, there is a miss understanding by the BizTalk Server engine, that happens from time to time.

In my case I was sure and I validate that the DLL and that particular version was deployed… In this cases, changing the DLL version (for example 1.0.0.1) and deploy the solution will solve it every time.

  1. i have the same problem but this didin´t solved my problem…
    There was a failure executing the receive pipeline: “Microsoft.BizTalk.DefaultPipelines.XMLReceive, Microsoft.BizTalk.DefaultPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35” Source: “XML disassembler” Receive Port: “RP_DB” URI: “C:BizTalk_WorkFolderreceive*.xml” Reason: The document specification from assembly failed to load. Verify the schema for this document specification is deployed and is in the Global Assembly Cache.

    1. There are a couple of things you need to do, when you run into this type of error in your case:
      – redeploy the assemblies (schema’s) you are using, my suggestion is to make a different dll version, and make sure you are restarting all the hosts.
      – In additional, you can stop the application and delete the assemblies from the application and GAC, and then redeploy the new assemblies.
      – use processmonitor or filemon to see where BizTalk is looking for the file can helped you.
