Why retrofit returns null in response body? - kotlin

Question

Get null response results in response body. Using retrofit, dagger and repository. Why get null in response I don't know. My model seem right. Whats the problem?
MainViewModel.kt
#HiltViewModel
class MainViewModel#Inject constructor(
private val repository: MovieRepository,
#ApplicationContext private val context: Context
) : ViewModel() {
val movieList = MutableLiveData<Resource<Movie>>()
fun getAllMovies(movieName: String) {
movieList.postValue(Resource.Loading())
viewModelScope.launch {
try {
if (hasInternetConnection(context)) {
val response = repository.getMovies(movieName, "ffe9123f")
movieList.postValue(Resource.Success(response.body()!!))
} else
movieList.postValue(Resource.Error("Internet yok"))
} catch (ex: Exception) {
when (ex) {
is IOException -> movieList.postValue(Resource.Error("Network Failure " + ex.localizedMessage))
else -> movieList.postValue(Resource.Error("Conversion Error"))
}
}
}
}
}
Resource.kt
sealed class Resource<T>(
val data: T? = null,
val message: String? = null
) {
class Success<T>(data: T): Resource<T>(data)
class Error<T>(message: String, data: T? = null): Resource<T>(data, message)
class Loading<T> : Resource<T>()
}
MovieRepository.kt
#Singleton
class MovieRepository #Inject constructor(private val movieAppService: MovieAppService) {
suspend fun getMovies(title: String, aKey: String): Response<Movie> = withContext(
Dispatchers.IO
) {
val movies = movieAppService.getMovies(title = title, aKey = aKey)
movies

Answer 1

Movie model is wrong. I didn't realize the starting letter is uppercase letter.
Movie.kt
data class Movie(
val Title: String,
val Year: String,
val Rated: String,
val Released: String,
val Runtime: String,
val Genre: String,
val Director: String,
val Writer: String,
val Actors: String,
val Plot: String,
val Language: String,
val Country: String,
val Awards: String,
val Poster: String,
val Ratings: List<Rating>,
val Metascore: String,
val imdbRating: String,
val imdbVotes: String,
val imdbID: String,
val Type: String,
val Dvd: String,
val boxOffice: String,
val Production: String,
val Website: String,
val Response: String
)
