Error occured in chapter 7

Where I get an error

Architectural Skeleton - MVVM News App Around 4:00

NewsActivity.kt. (onCreate function.)

override fun onCreate(SavedInstanceState: Bundle?){

......

val repository = NewsRepository(ArticleDatabase(this)
# In this line following error occured.
/*
Error
Type mismatch. 
Required: ArticleDatabase
Found:Unit
*/
}

I changed 'invoke' function in ArticleDatabase.kt as follows and it seems works without snag(I don't know it is right way or not though....)

operator fun invoke (context:Context) : ArticleDatabase {
return instance ?: synchronized(LOCK){
instance ?: createDatabase(context).also{ instance = it }
}

Thank you for your awesome videos and great instruction!!

use dagger to inject ArticleDataBase class into RepositoryClass -> like that

@Inject
db : ArticleDataBase
