APIGGE SOAP PASS through proxy error : org.xml.sax.SAXException: Invalid element

[chinmoy2010]

I have created a pass through soap proxy with base path '/v1/mobile-service'. I want to route the target endpoint to '/v1/mobile-service/firstApi'. When I am calling the soap api via 'https://<hostname>:/v1/mobile-service/firstApi', it is throwing org.xml.sax.SAXException: Invalid element error. 

  <HTTPProxyConnection>
    <BasePath>/v1/mobile-service</BasePath>
    <Properties/>
    <VirtualHost>secure</VirtualHost>
  </HTTPProxyConnection>
  <RouteRule name="default">
    <TargetEndpoint>default</TargetEndpoint>
    <Condition>proxy.pathsuffix MatchesPath "/firstApi"</Condition>
  </RouteRule>

it is throwing org.xml.sax.SAXException: Invalid element error.

What is IT in this case? When specifically do you see this error? When you submit a request? When you try to deploy the API Proxy?

Have you identified the source of the error? Is it the upstream service? Is it the Apigee Proxy? Something else?
