I am new with dagger using. So, I can't solve whats the problem with this. I just want to ask here to solve it.

This is the error:

Do not wrap your singleton object module with a same named class. Change your module file like this or change your class name

@Module
@InstallIn(SingletonComponent::class)
object ApiModule {
    
    @Provides
    @Singleton
    fun provideLoggingInterceptor(): HttpLoggingInterceptor {
        return HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)

            .connectTimeout(15, TimeUnit.SECONDS) // connect timeout
            .readTimeout(15, TimeUnit.SECONDS)
