QueryInstance.AddItemData<UEnvQueryItemType_Point>() HELPPP!!

I want to create a custom EnvQueryGenerator_BlueprintBase, But After I finished writing the code, I found that it crashed when it was running。

This Is My .h File

#include "CoreMinimal.h"
#include "EnvironmentQuery/Generators/EnvQueryGenerator_BlueprintBase.h"
#include "MyEQG_BlueprintBase.generated.h"

/**
 * 
 */
UCLASS()
class GETSTARTED_API UMyEQG_BlueprintBase : public UEnvQueryGenerator_BlueprintBase
{
	GENERATED_BODY()
	
	UMyEQG_BlueprintBase();

	virtual void GenerateItems(FEnvQueryInstance& QueryInstance) const override;
	virtual FText GetDescriptionTitle() const override;
	
public:

	UPROPERTY(EditAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
	uint8 Nums = 10;

	UPROPERTY(EditAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
	int Gap = 50;
};

This Is My .cpp file

// Fill out your copyright notice in the Description page of Project Settings.


#include "MyEQG_BlueprintBase.h"
#include "EnvironmentQuery/Items/EnvQueryItemType_Point.h"

UMyEQG_BlueprintBase::UMyEQG_BlueprintBase()
{
	ItemType = UEnvQueryItemType_Point::StaticClass();
}



void UMyEQG_BlueprintBase::GenerateItems(FEnvQueryInstance& QueryInstance) const
{
	
	TArray<FVector> Points;
	AActor* QuerierOwner = Cast<AActor>(QueryInstance.Owner.Get());

	if (!QuerierOwner) return;
	FVector ActorLocation = QuerierOwner->GetActorLocation();
	FVector ActorForwardVector = QuerierOwner->GetActorForwardVector();
	for (uint8 i = 1; i <= Nums; i++) {
		FVector Adder = ActorLocation + ActorForwardVector * i * Gap;
		Points.Add(Adder);
	}

	if (!QuerierOwner) return;
	int32 PointValueSize = GetDefault<UEnvQueryItemType_Point>()->GetValueSize();
	if (Points.Num() > 0)
		for (int i = 0; i < Points.Num(); i++) {
			QueryInstance.AddItemData<UEnvQueryItemType_Point>(Points[i]);
		}
	

}

FText UMyEQG_BlueprintBase::GetDescriptionTitle() const
{
	return FText::FromString(TEXT("CustomNode"));
}

And It’s It asserts in

QueryInstance.AddItemData<UEnvQueryItemType_Point>(Points[i]);

The Assertion Message

Assertion failed: GetDefault<TypeItem>()->GetValueSize() <= ValueSize [File:D:\Epic Game\UE_5.3\Engine\Source\Runtime\AIModule\Classes\EnvironmentQuery\EnvQueryTypes.h] [Line: 874]
