Can’t Load My UDebuffInfo PrimaryDataAsset via AssetManager

Hey everyone,

I’m trying to centralize all my debuff definitions in a single UPrimaryDataAsset so that both server and clients use the exact same data without having to manually replicate huge structs. Here’s my setup:

  1. DebuffInfo.h
// DebuffInfo.h
UCLASS()
class AURA_API UDebuffInfo : public UPrimaryDataAsset
{
  GENERATED_BODY()

public:
  // Jede Instanz bekommt anhand ihres Asset-Namens eine eindeutige ID
  virtual FPrimaryAssetId GetPrimaryAssetId() const override
  {
    return FPrimaryAssetId(FPrimaryAssetType("DebuffInfo"), GetFName());
  }

  // GameplayTag → Debuff-Parameter
  UPROPERTY(EditAnywhere, BlueprintReadOnly, Category="Debuff", meta=(Categories="Debuff"))
  TMap<FGameplayTag, FDebuffDefinition> DebuffDefinitions;
};
  1. EternalAssetManager.h
// EternalAssetManager.h
UCLASS()
class AURA_API UEternalAssetManager : public UAssetManager
{
  GENERATED_BODY()
public:
  static UEternalAssetManager& Get();

protected:
  virtual void StartInitialLoading() override;
};

// EternalAssetManager.cpp
UEternalAssetManager& UEternalAssetManager::Get()
{
  check(GEngine);
  return *Cast<UEternalAssetManager>(GEngine->AssetManager);
}

void UEternalAssetManager::StartInitialLoading()
{
  Super::StartInitialLoading();
  // wichtig für GAS-Target-Data in Multiplayer
  UAbilitySystemGlobals::Get().InitGlobalData();
}
  1. EternalAssetManager.cpp
// EternalAssetManager.cpp
UEternalAssetManager& UEternalAssetManager::Get()
{
	check(GEngine);

	UEternalAssetManager* EternalAssetManager = Cast<UEternalAssetManager>(GEngine->AssetManager);
	return *EternalAssetManager;
}

void UEternalAssetManager::StartInitialLoading()
{
	Super::StartInitialLoading();

	// this is required to use Target Data! (Important in multiplayer!)
	UAbilitySystemGlobals::Get().InitGlobalData();
}

I created a blueprint based on the DebuffInfo.h:

In Project Settings → Asset Manager I have added:

image795×413 11.9 KB

And this is how I want to load it:

static const FPrimaryAssetId DebuffInfoId("DebuffInfo", "DA_DebuffInfo");
UDebuffInfo* DebuffInfo = Cast<UDebuffInfo>(
    UEternalAssetManager::Get().GetPrimaryAssetObject(DebuffInfoId)
);
if (!DebuffInfo)
{
    UE_LOG(LogEternal, Error, TEXT("%s(): Failed to load DebuffInfo asset"), *FString(__FUNCTION__));
    return;
}

I always hit the error-log line (DebuffInfo is nullptr), even though the asset definitely exists in that location and I’ve configured the Asset Manager accordingly.

Am I missing something important?
Unfortunately I am new and dont really know how to help myself

Thanks in advance for any help! :folded_hands:
