How's koin works with properties in android?

Question

I found in official koin docs that properties default location is the src/main/resources/koin.properties , but when I trying to use it, I getting this beautiful exception. Can someone explain me how's koin works with properties on Android please?

E/AndroidRuntime: FATAL EXCEPTION: main

Class with onCreate():

override fun onCreate() {
        super.onCreate()
        startKoin {
            androidLogger(Level.NONE)
            androidContext(this@AppApplication)
                
            //copied from docs
            // Load properties from the default location 
            // (i.e. `/src/main/resources/koin.properties`)
            fileProperties("koin.properties") //CRASH

            modules(appModule)
        }
    }

Thing is that i should use use fileProperties() , without parameters, instead fileProperties("filename") . And then just use getProperty("property_name") .

That's because /src/main/resources/koin.properties is default location INCLUDING a filename...
