REST Webservice Exception Handling

Hi Experts,

I am working on a synchronous scenario Proxy to Rest web service and I have been given a requirement to capture the exceptions

that will get thrown from the webservice . They have not shared a fault message type WSDL structure .

Is there any possible way to capture the exceptions thrown by the REST webservice and pass it back to the service consumer Proxy. A sample exception thrown by the webservice as below.

<ns3:error>

</ns3:error>
