Description

When submitting a GET request to a synapse proxy service that points to a REST webservice
AND Content-Type is not text/xml or application/xml the error: "Cannot create DocumentElement without destination EPR" comes out. (e.g try to approach the service proxy with a webbrowers and it will do this)

configuration is as follows:

<definitions xmlns="http://ws.apache.org/ns/synapse">
<proxy name="Forwarder">
<target>
<endpoint>
<address uri="http://localhost:11111/MyService/echo" format="get"/>
</endpoint>
<outSequence>
<send/>
</outSequence>
</target>
</proxy>
</definitions>

If the message is send with the 'correct' content-type like for example so:
curl -G -H "Content-Type: text/xml" http://localhost:8280/Forwarder/mediate
Synapse gives me the following output:
