Пытаюсь получить список новостей следующим образом:

VK.execute(NewsfeedService().newsfeedGet(count = 300), object : VKApiCallback<NewsfeedGenericResponseDto> {
  ...
}

Получаю следующую ошибку:

Я исправил ошибку, заменив некоторые классы и функции на свои собственные, и понизив версию API в NewApiRequest до 5.81.
