Koin Annotations failing when module function return type is nullable

[hellosagar]

Describe the bug I'm using Koin Annotations. I have a NetworkModule class, and when I assemble the APK, I get an error when the return type is currently nullable string. However, when I change the return type to non-nullable String, it works fine.

To Reproduce Take the snippets from the below on your machine and try to assemble the APK; Koin will throw an error.

Expected behaviour On assembling the APK, it should work for nullable return types, too.

Koin module and version: io.insert-koin:koin-bom:4.0.0 io.insert-koin:koin-annotations-bom:1.4.0-RC4 ksp("io.insert-koin:koin-ksp-compiler:1.4.0-RC4")

Snippet or Sample project to help reproduce

@Module
@ComponentScan("foo.bar.sugar")
class NetworkModule {

@Single
    @Named("appDeviceName")
    fun provideDeviceName(
        context: Context,
        @Named("appSettingsSharedPreferences") sharedPref: SharedPreferences,
    ): String? {
        return sharedPref.getString(context.getString(R.string.settings_device_name_key), null)
    }

    @Single
    @Named("appDeviceLocation")
    fun provideDeviceLocation(
        context: Context,
        @Named("appSettingsSharedPreferences") sharedPref: SharedPreferences
    ): String? {
        return sharedPref.getString(context.getString(R.string.settings_device_location_key), null)
    }
}
