I want custom object in response of API having [required] data annotation on model properties like this:

{
   "resourceType": "OperationOutcome",
   "issue": [
     {
       "severity": "fatal",
       "code": "required",
       "location": [
         "/f:AllergyIntolerance/f:status"
       ]
     }
   ]
 }

Is it possible to do it or I would have to code it.

Because model validation happens before action is called, is there any way I can do it?
