Before entering javascript controller ,webscript framework will first parse request content and try to convert it to JSON using org.json.JSONObject class.
If it can't be converted to json object ,an exception with "Failed to convert request to JSON" will be thrown,and you still can get http response with exception information like below





{
    "status" :
  {
    "code" : 500,
    "name" : "Internal Error",
    "description" : "An error inside the HTTP server which prevented it from ful

Hi,
for me it is still unclear how can I intercept this exception since all I have is my post webscript.
Do you mean I should put this code between a try/catch clause?
How did you managed to get the exception you're showing in the post?

Regards,
Andrea

It is just common response ,only it's content is filled with integer status code and exception detail information instead of node data.
The response body is llegal json format ,you can parse the json string and get integer status code,if it is other than 200,then something wrong happens.
