Я занимаюсь разработкой новостного приложения. Я реализовал несколько модулей koin в своем проекте, но получаю следующие исключения

ниже моего модуля зависимостей koin appModules.kt 

val appModules = module() {
    factory(named("appModules")) {
        //NewsRepository.NewsRepositoryImpl(sportsNewsApi = get())
    }
    // factory<NewsRepository> { (NewsRepositoryImpl(sportsNewsApi = get())) }
    // Specific viewModel pattern to tell Koin how to build MainViewModel
    viewModel { MainViewModel(newsRepository = get(named("appModules"))) }



}

ниже NewsRepository.kt 

 class NewsRepository(private val sportNewsApi: SportNewsInterface, private val sportNewsDao: SportNewsDao) {

            val data = sportNewsDao.getAllData()

            suspend fun refresh() {
                withContext(Dispatchers.IO) {
                    val articles = sportNewsApi.getNewsAsync().body()?.articles
                    if (articles != null) {
                        sportNewsDao.addAll(articles)
                    }
                }
            }
        }

    //    @Suppress("UNCHECKED_CAST")
    //    class NewsRepositoryImpl(
    //        private val sportsNewsApi: SportNewsInterface
    //    ) : NewsRepository {
    //        override suspend fun getNewsList(): UseCaseResult<List<Article>> {
    //
    //            return try {
    //                val result = sportsNewsApi.getNewsAsync().body()!!.articles
    //
    //
    //                UseCaseResult.Success(result)
    //            } catch (ex: Exception) {
    //                UseCaseResult.Error(ex)
    //            }
    //        }
    //    }

ниже моего MainViewModel.kt 

@Suppress("UNCHECKED_CAST")
class MainViewModel(val newsRepository: NewsRepository) : ViewModel(), CoroutineScope {
    // Coroutine's background job
    val job = Job()
    // Define default thread for Coroutine as Main and add job
    override val coroutineContext: CoroutineContext = Dispatchers.Main + job

    val showLoading = MutableLiveData<Boolean>()
    val sportList = MutableLiveData<List<Article>>()
    val showError = SingleLiveEvent<String>()

    fun loadNews() {
        // Show progressBar during the operation on the MAIN (default) thread
        showLoading.value = true
        // launch the Coroutine
        launch {
            // Switching from MAIN to IO thread for API operation
            // Update our data list with the new one from API
            val result = withContext(Dispatchers.IO) {
                newsRepository?.data
                newsRepository.refresh()
            }
        }
    }
}
            // Hide progressBar once the operation is done on the MAIN (default) thread
//            showLoading.value = false
//            when (result) {
//
//                is LoadingState.Status {
//                    sportList.value = result.as List < Article >
//                }
//                is Error -> showError.value = result.message
//            }
//        }
//    }

//    override fun onCleared() {
//        super.onCleared()
//        // Clear our job when the linked activity is destroyed to avoid memory leaks
//        job.cancel()
//    }
//}

Я хочу знать, где я делаю ошибку, почему происходит сбой приложения.

что я пробовал

1.Не допустить перезапуск кэша 2. Построить проект перестроения и выполнить все ответы StackOverflow
