public function render($request, Exception $exception)
{
 if($request->is('api/')){
  $response = [];
  $error = $this->convertExceptionToResponse($exception);
  $response['status'] = $error->getStatusCode();
  $response['msg'] = 'something error';
  if(config('app.debug')) {
   $response['msg'] = empty($exception->getMessage()) ? 'something error' : $exception->getMessage();
   if($error->getStatusCode() >= 500) {
    if(config('app.debug')) {
     $response['trace'] = $exception->getTraceAsString();
     $response['code'] = $exception->getCode();
    }
   }
  }
  $response['data'] = [];
  return response()->json($response, $error->getStatusCode());
 }else{
  return parent::render($request, $exception);
