tRESTClient doesn't propagate message body on DELETE

I'm creating a full REST service with tRESTRequest and tRESTResponse components. GET and POST are working fine, but DELETE give me some trouble. I created a simple client to test the service, as you can see in first image attached.
A debug run shows that body is null, but when you see full log, outbound and inbound messages are correct:
connecting to socket on port 3543
connected
connecting to socket on port 4827
connected

Why payload is not present in Response flow?
Thank you so much.

Hi,
DELETE is not expected to contain the body, not a 'must' requirement but Java HttpUrlConnection actually enforces it.
We can have it done in CXF alone by delegating to CXF HttpClient asynchronous conduit, but we do not have it supported in the studio.
Consider avoiding using DELETE with the body, unless you have a task of integrating with the legacy servers that do expect it, and if you do have such a case then check tHTTP* client components, one of them may actually use Apache HttpClient

Ok, thank you. It was confusing see it on log message

But, if so, why in tRESTRequest a DELETE verb "must" have a "Produce" field filled with something? You must fill it with XML or JSON or at least "any".

Blocking Produces completely in case of DELETE might be too restricting, we do not know of the actual client requirements, example, a client may want to get some confirmation...Note, even though Produces is enabled, there's no requirement for DELETE server flow to return any data back
