I can't attach actor to another acctor

I want to attach an actor to another actor when they collide.
I wrote the following code but although it shows the debug message, AttachToComponent always return false.

The OtherActor is the player control mannequin, and the ACubeActor is a cube with static mesh, which I created by following one of the tutorial that I found on UE5’s official documentation.

void ACubeActor::OnHit(UPrimitiveComponent *HitComp, AActor *OtherActor, UPrimitiveComponent *OtherComp, FVector NormalImpulse, const FHitResult &Hit)
{
	if (OtherActor != NULL)
	{
		GEngine->AddOnScreenDebugMessage(-1, 1., FColor::Red, OtherActor->GetName());
	
		auto got = AttachToComponent(
			OtherActor->GetRootComponent(), 
			FAttachmentTransformRules::SnapToTargetIncludingScale
		);
		
		GEngine->AddOnScreenDebugMessage(-1, 1., FColor::Red, got ? "true" : "false");
	}
}

I’m new to Unreal and any help is appreciated.
