How to send exact errors in REST API inbound without passing the hard coded string value

[Sharique Azim]

Can some one kindly instruct me ,how to send error in responses,whenever you get any bad request WITHOUT giving the same string message?

For example:

{
  "error": {
    "message": "The undefined value has no properties.",
    "detail": "ConversionError: The undefined value has no properties. (sys_ws_operation.e76abaa11b0a6300de0efcccdd4bcb4d.operation_script; line 23)"
  },
  "status": "failure"
}

 Now,incase this has some other error reasons, i would like to send in the exact message and details. and not some generic message.

Please note: i  have gone through Scripted REST API error objects and related docs before raising this post.

I found out a way to send out the error message.  Doesnt works directy like in Docs(most probably due to scope issues)

For those intrested:

var bdy=request.body.data;

try{

//some logic}

catch(e){

var err=JSON.stringify(e);
var req_bdy =JSON.stringify(bdy);

response.setContentType('application/json');
var resp=response.getStreamWriter(),
hdrs = {};

hdrs['Content-Type'] = 'application/json';
response.setStatus(400);
response.setHeaders(hdrs);
resp.writeString("{\"results\":[");
resp.writeString(err);
resp.writeString("]}");
gs.info('POST BAD request:'+req_bdy.toString()+'\nError:'+err);

}

For some reasons, i was not able to use object serializing method here.

Although marked correct initially, if a better approach is provided. i would mark that response correct.
