I need help with rotating DirectLight from c++

[Dsvua]

I am trying to move/rotate Directional Light from my Player Controller. This is what in my header:

UCLASS()
class ABaseBuildingGamePlayerController : public APlayerController
{
	GENERATED_BODY()
...
...
protected:
	UPROPERTY(BlueprintReadWrite, EditAnywhere, Category = "Settings|Camera")
	ADirectionalLight* DirectionalLightSource = nullptr;
...
...
}

Then in my cpp file I added to one of functions (better place would be beginplay, but for testing it executes every tick):

		if (IsValid(DirectionalLightSource)){
			DirectionalLightSource->AddActorWorldRotation(FRotator(MovementScaled.X, MovementScaled.Y, 0));

		} else {

			TArray<AActor*> FoundLights;
			UGameplayStatics::GetAllActorsOfClass(GetWorld(), ADirectionalLight::StaticClass(), FoundLights);

			if(GEngine)
				GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, FString::Printf(TEXT("DirectionalLightSources found %f"), FoundLights.Num()));

			for (AActor* TActor : FoundLights)
			{
				if (TActor->GetName().Equals("SunLight"))
				{
					DirectionalLightSource = Cast<ADirectionalLight>(FoundLights[0]);
					break;
				}
			}
		}

However, I got printed DirectionalLightSources found 0.000000. Why I cannot get any DirectionalLight when there definitely one in outline?

@Dsvua

FString::Printf(TEXT("DirectionalLightSources found %f"), FoundLights.Num())

.Num() returns int32. Should be %i not %f.
