  <p>Is there any possibility to enable more debug options to get more information about this particular exception so that it will be easy to find out the root cause.</p>
  
  <p>The problem here is, even though i am not using the payload in transform message i am getting error because of the payload returned by the previous http call in muleflow.</p>
  
  <p>Mule version is : studio 6.1 and runtime 3.8.</p>
  
  <p>Please help me to solve this issue.</p>
  
  <p>Thanks
