UE4 C++: Importing Fbx using AssetTools

Hi i have a fully functional fbx file that i’m trying to import into Unreal editor and having it into content browser, so i investigated how the Fbx impor works and i’m using this code:

TArray<FString> OpenFilenames;
    		
OpenFilenames.Add("D://DA - Utilities//UE4//file.FBX");
    
FModuleManager::LoadModuleChecked<FAssetToolsModule>("AssetTools").Get().ImportAssets(OpenFilenames, FString(*UTF8_TO_TCHAR("/Game"), NULL));

But the third line generates an exception.

There is someone that have managed to succesfully use AssetTools in C++?
Thanks.
