Can't store closest hit result in a pointer

Sorry forgot to mention. The Trace function is just calling the LineTracingByChannel with some extra debug lines and points.

{
	FVector End = Start + (Direction * Length);
	FCollisionQueryParams CollisionParameters;
	CollisionParameters.AddIgnoredActor(this);
	bool bIsHit = GetWorld()->LineTraceSingleByChannel(HitResult, Start, End, ECC_WorldDynamic, CollisionParameters);
	DrawDebugLine(GetWorld(), Start, End, FColor::Green);
	if (bIsHit)
	{
		DrawDebugPoint(GetWorld(), HitResult.ImpactPoint, 5.f, FColor::Orange);
	}
	return bIsHit;
}
