Where should GEComponents be created in C++?

After the changes to GAS in UE 5.3, I saw that GameplayEffects use Components when requiring/applying GamplayTags. So I tried to transfer all the GameplayTags logic from the GE’s C++ Constructor to GEComponents, but I couldn’t find where exactly should I create Components. The constructor didn’t work because they don’t have a Name or something, then I tried in PostInitProperties but my OngoingTagRequirements didn’t work after creating a build.
May someone tell me where should GEComponents be created in C++?

I’m interested to know what the intended place is too. It looks like you can override UGameplayEffect::PostCDOCompiled, add the components yourself and then call super which has backwards compatiblity that will work with your manually added components. However, that only works in Editor builds.

I know this is a late reply, but I recently encountered the same issue. In my case, the GEComponents array in the GameplayEffect class needed to be initialized correctly to resolve the console error. I treated it like any other component by creating it with CreateDefaultSubobject and adding it directly to the GEComponents array. Here’s the code that worked for me:

#pragma once

#include "CoreMinimal.h"
#include "GameplayEffect.h"
#include "GameplayEffectComponents/TargetTagsGameplayEffectComponent.h"
#include "UCustomEffect.generated.h"

/**
 * 
 */
UCLASS()
class ARCANA_API UCustomEffect : public UGameplayEffect
{
	GENERATED_BODY()

public:
	UCustomEffect()
	{
		DurationPolicy = EGameplayEffectDurationType::Infinite;

		UTargetTagsGameplayEffectComponent* TagsComponent = CreateDefaultSubobject<UTargetTagsGameplayEffectComponent>(
			TEXT("TagsComponent")
		);
		GEComponents.Add(TagsComponent);

		FInheritedTagContainer Tags = TagsComponent->GetConfiguredTargetTagChanges();
		Tags.AddTag(FGameplayTag::RequestGameplayTag(FName("Your.Tag.Name")));
		TagsComponent->SetAndApplyTargetTagChanges(Tags);
	}
};

I hope this helps!
