Получение ошибки разбиения на страницы в данных Android, которые не загружаются после определенной страницы в Android ⇐ Android

[Anonymous]

Я делал разбиение на страницы в Android Kotlin, но когда я пытался загрузить данные, я получал данные до страницы 4, и также был вызван API для страницы 5, и я проверил его ответ в logcat, но данные не были загружены в recyclerView.
вот код для этой части
класс HomeFragment : Fragment(), HomeAdapter.OnItemClickListener {

Код: Выделить всё

private var _binding: FragmentHomeBinding? = null
lateinit var homeViewModel: HomeViewModel

private var isLoading = false
private var currentPage = 1
private var totalPages = Int.MAX_VALUE // Placeholder, update based on API response
private lateinit var homeAdapter: HomeAdapter
private val requestedPages = mutableSetOf()

// This property is only valid between onCreateView and
// onDestroyView.
private val binding get() = _binding!!

override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
homeViewModel = ViewModelProvider(this).get(HomeViewModel::class.java)

_binding = FragmentHomeBinding.inflate(inflater, container, false)
val root: View = binding.root
