I got a class extended from UBTDecorator_Blackboard and I am getting errors not in my inherited class but in the base class i.e. UBTDecorator_Blackboard

Here is my code

.h
#pragma once

#include "BehaviorTree/Decorators/BTDecorator_Blackboard.h"
#include "BTDecorator_BBTest.generated.h"

/**
 * 
 */
UCLASS()
class AITEST_API UBTDecorator_BBTest : public UBTDecorator_Blackboard
{
	GENERATED_UCLASS_BODY()

	virtual bool CalculateRawConditionValue(class UBehaviorTreeComponent* OwnerComp, uint8* NodeMemory) const override;

	/** blackboard key selector */
	UPROPERTY(EditAnywhere, Category = Blackboard)
	struct FBlackboardKeySelector BotSelectedKey;
	
};

.cpp
#include “AITest.h”
#include “AI/MyAIController.h”
#include “BTDecorator_BBTest.h”

UBTDecorator_BBTest::UBTDecorator_BBTest(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{

}

bool UBTDecorator_BBTest::CalculateRawConditionValue(class UBehaviorTreeComponent* OwnerComp, uint8* NodeMemory) const
{

	UBehaviorTreeComponent* MyComp = OwnerComp;
	AMyAIController* OwnerController = Cast<AMyAIController>(MyComp->GetOwner());

	const UBlackboardComponent* BlackboardComp = OwnerComp->GetBlackboardComponent();
	if (BlackboardComp)
	{
		FBlackboard::FKey KeyID = BotSelectedKey.GetSelectedKeyID();
		bool bIsSelected = BlackboardComp->GetValueAsBool(KeyID);
		GEngine->AddOnScreenDebugMessage(-1, 0.05, FColor::Black, bIsSelected ? TEXT("true") : TEXT("false"));
		if (bIsSelected)
		{
			GEngine->AddOnScreenDebugMessage(-1, 0.05, FColor::Black, "works2");
			return true;
		}
	}
	return false;
}

Errors I am getting

Could you fix this or find a workaround? I’m having the same problem.

extend the class from UBTDecorator instead.
