                ))
                .Process(formData)
               .Data();
                return Json(response, JsonRequestBehavior.AllowGet);
            }
        }

i have a type and id, and based on the type i want to return the correct result with where, but if i add if statement always i didn't get the data, and always get
"Uncaught TypeError: Cannot read property 'length' of undefined"

What is the condition you want to use? Assuming you always want to run the Editor code, but optionally add an Where() statement, you could do:

.Where( q => {
  if ( ... ) {
    q.Where( ... );
  }
} )
