Hi Niranjan. I think this only happens when you have content aware mediators in your sequence(You can check with removing full log mediators). Inside the RelayUtils we are checking status code equal to the 202[1] and ignore build the response body. So reason could be this. You can debug the RelayUtils to confirm the behavior.
