I'm sending request like:

curl -v -H "Accept:application/json" -H "Content-Type:application/json"  -d '{"username":"Harry","userid":"347367127872701992"}' http://youtility-desktop:8282/services/Capp_LoginProxy

How should i fix the error? Please let me know..

curl -v -H "Accept:application/json" -H "Content-Type:application/json" -d '{"mailid":"[email protected]",phonenumber":"999999999"}' youtility-desktop:8282/services/Capp_muser_Registration — user3129056
What about your log mediators ? Are they getting printed ? You cannot use XPATH expressions to manipulate a json request. Try this <property name="username" expression="json-eval($.username)"/> For more info refer this — chanaka777
thanks chanaka777 for reply..I got the answer..This error is actually in dss but showing it in esb..I have to make changes in operation section while writing query at dss.. Return Request Status checkbox must be on.. — user3129056

I got the same issue in ESB 5 and DAS 3. It could get fixed by adding relevant messageFormatters and messageBuilders in axis2.xml located in esb/repository/conf/axis2.xml

In my scenario, these two entries were added to axis2.xml

messageFormatter contentType="text/html" class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>

messageBuilder contentType="text/html" class="org.wso2.carbon.relay.BinaryRelayBuilder"/>
