MessageID of the response is recognized as the wsa:RelatesTo instead of the actual MessageID

[karunarathneeshani]

When the wsa:RelatesTo header is unspecified in the response of the WS-enabled service, the messageID should be used in MI to correlate the backend response with the request. But currently, the MessageID of the response is recognized as the wsa:RelatesTo instead of the actual MessageID.

Steps to reproduce:

Create a WS-enabled proxy service where the backend of this proxy service returns the wsa:RelatesTo header as http://schemas.xmlsoap.org/ws/2004/08/addressing/id/unspecified.

The message flow will fail with the following error.

TS: [] TID: [] [2024-03-20 09:50:58,614] WARN {SynapseCallbackReceiver} - Synapse received a response for the request with message Id : http://www.w3.org/2005/08/addressing/unspecified and correlation_id : xxx But a callback is not registered (anymore) to process this response
