Recently I have been working on a really simple case. When an HTTP server returned an error and a non-empty body, I needed to embed this body into an error structure. Although this is a simple case, I got a problem with implementing it in Mule 4. In the previous Mule edition, it was a little bit simpler. So let's see what it is all about.
Case
First, we have a look at the case that I have to implement. I have a mule application that is calling an external HTTP server via an HTTP request component. When the server responds with an error like 4xx, 5xx, and the returned body will is not empty, we would like to forward that response to the calling application.
