One of the Virtual service we deployed is sending only mock data and its not returning the live responses.
The back end live system is throwing Null pointer exception.
All supported DevTest environments
This is a limitation with DPH's that changes request body if the Live system is expecting the original version of the request. You need the DPH-modified version of a request for doing model healing, stand-in mode, failover mode, dynamic execution mode, etc. But you still need the original version of request for forwarding to the live service.
So to bypass this , the only thing you can do is to have two versions of the VSM, one with the DPH and one without it.
Steps to Follow:
Create two VSM's ,
1. One with DPH to parse the request body
2. One without DPH, so you can send the request to the live system in its original form.
