Dagger 2. Не могу разобраться в чем ошибка!

Всем привет! Помогите пожалуйста разобраться с ошибкой Dagger 2. Вот то, что выдают мне логи. Я к сожалению новичок и не могу самостоятельно разобраться с проблемой.

Вот код AppRepository:

import com.astar.osterriglampled.repository.database.AppDatabase
import com.astar.osterriglampled.repository.database.entity.Lamp
import io.reactivex.Single
import io.reactivex.android.schedulers.AndroidSchedulers
import io.reactivex.schedulers.Schedulers

class AppRepository(private val mainDatabase: AppDatabase) {

    fun getAllLamps(): Single<List<Lamp>>? {
        return Single.just(mainDatabase.lampDao().getLamps())
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
    }

    fun getLampByGroups(id: Long): Single<List<Lamp>>  {
        return Single.just(mainDatabase.lampDao().getLampsByGroup(id))
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
    }

    fun getLampById(id: Long): Single<Lamp> {
        return Single.just(mainDatabase.lampDao().getLampById(id))
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
    }

}

Код RepositoryModule

package com.astar.osterriglampled.di.module

import AppRepository
import com.astar.osterriglampled.repository.database.AppDatabase
import dagger.Provides

class RepositoryModule {

    @Provides
    internal fun providesRepository(database: AppDatabase): AppRepository {
        return AppRepository(database)
    }
}

И код RepositoryComponent

@RepositoryScope
@Component(modules = [RepositoryModule::class], dependencies = [DatabaseComponent::class])
interface RepositoryComponent {
    val repository: AppRepository
}
