I'm new in Koin and I've stuck with this error for a long time. This error is found when I run the code on emulator. I have no idea how to solve this. So, Do anyone have any suggestion?

Here, there're classes that I think its cause the error.
SearchFragment.kt , SearchViewModel.kt, UserImpl.kt, RetrofitBuilder.kt
class SearchFragment : Fragment() {
private val vm: SearchViewModel by viewModel()
.....
.......
class SearchViewModel(private val userImpl: UserImpl) : ViewModel() {
private val disposable = CompositeDisposable()
....
......
class UserImpl(private val gitHubApi: GitHubApi) : UserRepository {
override fun getSearchUser(str: String?): Observable<SearchUserResponse> {
return gitHubApi.searchUsers(str)
}
}
interface UserRepository {
fun getSearchUser(str: String?): Observable<SearchUserResponse>
}
class RetrofitBuilder(val okHttpClient: OkHttpClient,
val converterFactory: Converter.Factory,
val adapterFactory: CallAdapter.Factory) {
inline fun <reified T> build(baseUrl: String): T {
return Retrofit.Builder()
.client(okHttpClient)
.baseUrl(baseUrl)
.addConverterFactory(converterFactory)
.addCallAdapterFactory(adapterFactory)
.build()
.create(T::class.java)
}
}
This is my modules.
val appModule = module {
factory<UserRepository> { UserImpl(get()) }
viewModel { SearchViewModel(get())}
}
val networkModule = module {
single {
HttpLoggingInterceptor().apply {
this.level = HttpLoggingInterceptor.Level.BODY
}
}
single {
object : Interceptor {
@Throws(IOException::class)
override fun intercept(chain: Interceptor.Chain): Response {
val original: Request = chain.request()
val originalHttpUrl = original.url
val url = originalHttpUrl.newBuilder()
.build()
// Request customization: add request headers
val requestBuilder = original.newBuilder().url(url)
val request = requestBuilder.build()
val response = chain.proceed(request)
return response
}
}
}
single {
OkHttpClient.Builder()
.addInterceptor(get<HttpLoggingInterceptor>())
.addInterceptor(get<Interceptor>())
.build()
}
single<CallAdapter.Factory> { RxJava2CallAdapterFactory.create() }
single<Converter.Factory> { GsonConverterFactory.create() }
single { RetrofitBuilder(get(), get(), get()) }
single<GitHubApi> { get<RetrofitBuilder>().build(GITHUB_BASE_URL) }
}
