InternalServiceFault - The value of a promoted property cannot exceed 256 characters. Property "Action" Namespace "http://schemas.microsoft.com/BizTalk/2006/01/Adapters/WCF-properties".

I tried to invoke a WCF service from within an orchestration and got the below fault message in response


<Fault xmlns="http://www.w3.org/2003/05/soap-envelope"><Code><Value>Receiver</Value><Subcode><Value xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">a:InternalServiceFault</Value></Subcode></Code><Reason><Text xml:lang="en-US">The server was unable to process the request due to an internal error.  For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the &lt;serviceDebug&gt; configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.</Text></Reason></Fault>

after IncludeExceptionDetailInFaults = ture got below exception.

The problem was solved.

In my case WCF service (logical)port operation name from orchestration was not equal with operation name in physical port binding properties.

or 

Go to send port -> Configure and SOAP Action Header section.

Remove below lines

<BtsActionMapping xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Operation Name="OperationXXXName1" Action="OperationXXXName1" />
  <Operation Name="OperationXXXName2" Action="OperationXXXName2" />
</BtsActionMapping>

And keep only one action in the SOAP Action Header section. (i.e OperationXXXName1).
