Encountered the following error today on a SOAP [Send] Port:
Failed to serialize the message part “[PART NAME]” into the type “[MESSAGE TYPE]” using namespace “[NAMESPACE]”. Please ensure that the message part stream is created properly.
The error is a little misleading, especially ‘ensure that the message part stream is created properly‘ – the message part stream is created correctly, but it does not match the type contained within the SOAP adapter proxy and therefore fails to serialize. In our case, we were trying to serialize an element with the string ‘Stan’ into a boolean. With the best will in the world, that isn’t going to happen!
To check where the problem lies with serialization, simply validate the failed message (retrieved from the Admin Console) against the schema generated from the WSDL, using the Visual Studio ‘Validate Instance‘ schema menu option. You’ll be presented with a list of errors that can then be resolved.
Our problems went a lot further and resulted in a fairly impressive hacky bodge that I am extremely proud of, especially on a Friday at 5pm (with a Bank Holiday weekend waiting for me). I’ll spare you that for another post!
