WSO2 APIM API invocation error

Question

I have set up WSO2 API Manager and set up an API. Tried to invoke it via APIM console itself .But it says NO response from client.

I enabled log4j.logger.org.apache.synapse.transport.http.wire=DEBUG and found out the below error in the wso2-apigw-errors.log.

Can someone please help?

attach logs is something related to data publisher. if you enable wire log request and response will get printed as in blog http://mytecheye.blogspot.com/2013/09/wso2-esb-all-about-wire-logs.html — Jenananthan, Dec 28 '16 at 12:31

I have no error now..But i get response body as empty... Ideally the service should return a json.. Response Body no content – Janier Dec 29 '16 at 17:29
If the curl works but API console doesn't it can be a cert issue. Copy URL to browser and accept the cert. Then try again in API console. – Bee Dec 29 '16 at 18:10
curl itself is not working..The response code is 200 but response body is No Content and response headers is { "content-type": null } – Janier Dec 29 '16 at 18:19
if response code is 200, it's working. problem must be with the backend. post wire logs. – Bee Dec 29 '16 at 18:21
