AssetManager in cooked build doesnt work

Development Programming & Scripting

I’m using AssetManager and AssetRegistry to load content at runtime. It all works in Editor, but fails when using in cooked build.
Here Is how I initialize AssetRegistry:

#include "ActionRPGGame.h"
#include "Modules/ModuleManager.h"
#include "AssetRegistryModule.h"
#include "Engine/AssetManager.h"
void FActionRPGGameModule::StartupModule()
{
	FAssetRegistryModule& AssetRegistryModule = FModuleManager::LoadModuleChecked<FAssetRegistryModule>("AssetRegistry");
	IAssetRegistry& AssetRegistry = AssetRegistryModule.Get();
	//AssetRegistryModule.Get().OnFilesLoaded().AddUObject(this, &UARUIAbilityManagerComponent::FinishedLoadinFiles);
	TArray< FString > ContentPaths;
	TArray<FString> RootPaths;
	FPackageName::QueryRootContentPaths(ContentPaths);
	AssetRegistry.ScanPathsSynchronous(ContentPaths);

};
IMPLEMENT_PRIMARY_GAME_MODULE(FActionRPGGameModule, ActionRPGGame, "ActionRPGGame" );

Then:

FAssetRegistryModule& AssetRegistryModule = FModuleManager::LoadModuleChecked<FAssetRegistryModule>("AssetRegistry");
			IAssetRegistry& AssetRegistry = AssetRegistryModule.Get();

			TArray<FAssetData> AssetData;
			FARFilter Filter;
			Filter.TagsAndValues.Add("AbilityTagSearch", InAbilityTag.ToString());
			AssetRegistryModule.Get().GetAssets(Filter, AssetData);
			FPrimaryAssetId PrimaryAssetId = FPrimaryAssetId(FPrimaryAssetType("Ability"), AssetData[0].AssetName);
			FPrimaryAssetTypeInfo Info;
			if (Manager->GetPrimaryAssetTypeInfo(PrimaryAssetId.PrimaryAssetType, Info))
			{
				FStreamableDelegate del = FStreamableDelegate::CreateUObject(this, &UAFAbilityComponent::OnFinishedLoad, InAbilityTag, InInputName, PrimaryAssetId);

				Manager->LoadPrimaryAsset(PrimaryAssetId,
					TArray<FName>(),
					del);
			}

Which calls this function, when delegate is called:

void UAFAbilityComponent::OnFinishedLoad(FGameplayTag InAbilityTag,
	FGameplayTag InInputName, FPrimaryAssetId InPrimaryAssetId)
{
	if (UAssetManager* Manager = UAssetManager::GetIfValid())
	{
		UObject* loaded = Manager->GetPrimaryAssetObject(InPrimaryAssetId);
		TSubclassOf<UGAAbilityBase> cls = Cast<UClass>(loaded);
		if (cls)
		{
			NativeAddAbility(cls, nullptr, InInputName);
		}

		{
			Manager->UnloadPrimaryAsset(InPrimaryAssetId);
		}
	}
}

In turn it gets to this function:

const FPrimaryAssetData* UAssetManager::GetNameData(const FPrimaryAssetId& PrimaryAssetId, bool bCheckRedirector) const
{
	const TSharedRef<FPrimaryAssetTypeData>* FoundType = AssetTypeMap.Find(PrimaryAssetId.PrimaryAssetType);

	// Try redirected name
	if (FoundType)
	{
		const FPrimaryAssetData* FoundName = (*FoundType)->AssetMap.Find(PrimaryAssetId.PrimaryAssetName);
		
		if (FoundName)
		{
			return FoundName;
		}
	}

And it turns out that >AssetMap< Is empty for some reason in cooked build.

Any idea how to fix it ?

I think you need to add the folders/levels you want to load dynamically to be cooked in the project preferences

Have you ever solved this, iniside? Thanks in advance!
