Я устал отправлять список amazon IonStruct, который я получил, преобразовав результат из QLDB, в объект ответа.

Я пытался отправить 

final List<IonStruct> documentList = new ArrayList<>();
        result.iterator().forEachRemaining(row -> documentList.add((IonStruct) row));
return new ResponseEntity<>(list, HttpStatus.OK);

Но яполучил ошибку

final List<JSONPObject> list= new ArrayList<JSONPObject>();
for (IonStruct i:result
                ){list.add(new JSONPObject(i.toPrettyString(),Example.class));

           }
return new ResponseEntity<>(list, HttpStatus.OK);

Этот код работает для меня
