In a new integration consuming a SOAP service exposed by SAP PI the provider erroneously responds with an empty SOAP envelope. The WSDL specifies a one-way MEP.
The integration throws an error stating:
| Quote: |
| A SOAP request received a response message body when one was not expected because a one-way Messsage Exchange Pattern (MEP) was being used. |
However, the specification states that:
| Quote: |
| R2750 A CONSUMER MUST ignore an envelope carried in a HTTP response message in a one-way operation. |
http://www.ws-i.org/Profiles/BasicProfile-1.1.html#One-Way_Operations
It seems both (WMB and SAP PI) are at fault here but is there anyway of getting around this on my end?
WMB version 8.0.0.5 (64-bit Windows) |

Are you sure the wsdl you have is correct (and up to date) and that what you have is indeed (still) a one way operation?

I recently received the wsdl that team and they also informed me that the service it is supposed to be one-way. |

You do not have very many good options in this case. The ones I can think of are 1: Use an HTTPRequest node instead, which will not care about the response. 2: Change the WSDL to be two-way, 3: Raise a PMR and ask for an option to allow the WS-I requirement to be met.
Kind regards,

Thanks, I'll go for option 3 but it's good to know about 1 as well.
2 is risky if they suddenly patch their error away. |
