Hi Folks
I am also getting this issue in APIM 1.8.0 too. I created an new API and
navigate to the implementation page, then I have set my inline script like
below,
mc.setProperty('CONTENT_TYPE', 'application/json');
var jsonPayLoad = mc.getPayloadJSON();
mc.setPayloadJSON(jsonPayLoad);
After publishing the API, I send a curl POST request with sample json
payload to the API, but I could not see the results as i expected, Instead
it is given a empty bracket like this '{}'.
Please note I have enabled below properties in my axis2.xml
<messageFormatter contentType="application/json"
class="org.apache.synapse.commons.json.JsonStreamFormatter"/>
<messageBuilder contentType="application/json"
class="org.apache.synapse.commons.json.JsonStreamBuilder"/>
What could be the problem here?
Regards
Roshan.
