Mapping exception in RWB in an ICO SOAP(with XI) to SOAP scenario in PI 7.11

Hi Experts,

We are facing the below error while trying to post a to a webservice using SOAP. The scenario is from ECC to a third party. SOAP(with XI) to SOAP using ICO. When we trigger the payload using sproxy in dev landscpae it works fine. However in production, it fails with below error:

Execution of mapping failed. Reason: MappingException: 205

Transmitting the message to endpoint <local> using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.service.mapping.MappingException: 205.

Config and design is same in both landscapes. Please advise.

Regards,

Sriram
