Hilt cannot be provided without an @Provides-annotated method

I have a viewmodel for activity

@HiltViewModel
class MainViewModel @Inject constructor(
private val repository: UserRepository
)     : ViewModel() {

}

Repository interface

interface UserRepository {
suspend fun loginUser(username: String, password: String): Pair<Boolean, String>
}

User data source class is as follows

internal class UserDataSource @Inject constructor(private val octaveApi: OctaveApi) :
UserRepository {

override suspend fun loginUser(username: String, password: String): Pair<Boolean, String> {
    return Pair(false, "unsucess")
}
}

This is my dagger implementation

@Module
@InstallIn(SingletonComponent::class)
abstract class ApiModule {

  @Module
  @InstallIn(SingletonComponent::class)
  object Providers {

    @Provides
    @Singleton
    internal fun provideOctaveApi(retrofit: Retrofit): OctaveApi =
      retrofit.create(OctaveApi::class.java)
  }
}

@Module
@InstallIn(ActivityRetainedComponent::class)
abstract class RetainedDataModule {

  @Binds
  internal abstract fun bindUserRepository(userDataSource: UserDataSource):     UserRepository
}

When I build the project I get this error

/OctaveDashboard/app/build/generated/source/kapt/stagingExternalDebug/com/octave/OctaveApplication_HiltComponents.java:125: error: [Dagger/MissingBinding] com.octave.data.user.UserRepository cannot be provided without an @Provides-annotated method.

Can't seem to figure out what's causing the issue.

I was missing module dependencies in my app module which was creating this issue. Was able to fix by including it.
