Я реализовал Result.Success и Result.Error в моем классе ViewModel, но я получаю следующую ошибку в моем SecondActivity.kt C: \ Users \ Edgar \ AndroidStudioProjects \ GiphyAndroidApp \ app \ src \ main \ java \ com \ example \ giphyandroidapp \ ui \ SecondActivity.kt: (52, 52): Несоответствие типов: предполагаемый тип - Result ‹List?›, но List ожидался

под моим классом ViewModel, где я реализовал логику Result.Success и Result.Error
@HiltViewModel
class GiphyTaskViewModel
@Inject
constructor(private val giphyTaskRepository: GiphyTaskRepository):ViewModel()
{
var giphyresponse = MutableLiveData<Result<List<DataItem>?>>()
fun getGifsFromText(apikey:String,text:String,limit:Int)= viewModelScope.launch {
giphyTaskRepository.getGifsFromText(apikey,text,limit).let { response->
if(response?.isSuccessful){
var list=response.body()?.data
giphyresponse.postValue(Success(list))
}else{
Error(Exception(response.message()))
}
}
}
}
ниже класса репозитория
class GiphyTaskRepository
@Inject
constructor(private val giphyTaskApiService: GiphyTaskApiService)
{
suspend fun getGifsFromText(apikey:String,text:String,limit:Int)=
giphyTaskApiService.getGifsFromText(apikey,text,limit)
}
под моим сетевым интерфейсом
interface GiphyTaskApiService {
@GET("gifs/search")

@Query("limit") limit:Int

@Parcelize
data class GiphyResponse(
@field:SerializedName("pagination")
val pagination: Pagination,
@field:SerializedName("data")
val data: List<DataItem>,

val meta: Meta
) : Parcelable
ниже класса результата
sealed class Result<T>
data class Success<T>(val data: T) : Result<T>()
data class Error(val exception: Exception) : Result<Any?>()
Я хочу знать, что мне нужно сделать, чтобы успешно реализовать классы result.success и result.error и передать правильный параметр, чтобы избежать ошибки несоответствия
Я получаю несоответствие после выполнения ответа Мурата
