Game does not recognize function? (Callstack error)

Hello Guys! I’m trying to call a function from Steam API, but i’m getting fatal error when doing it.

Basically, i made this simple function from c++ that i’m calling from blueprint:

//

void UCountrifiedInventory::InitInventory(UInventory* Inventory, bool &bIsInventoryWorking)
{ if (!SteamAPI_Init())
{
[INDENT=2]UE_LOG(LogTemp, Warning, TEXT(“Fatal Error - Steam must be running to play this game - SteamAPI_Init() failed.”));
bIsInventoryWorking = false;[/INDENT]
}
else
{
[INDENT=2]UE_LOG(LogTemp, Warning, TEXT(“SteamAPI_Init() Called with Success.”));
bIsInventoryWorking = SteamInventory()->GetAllItems(&Inventory->s_SteamInventoryRef);[/INDENT]
[INDENT=2]if (!bIsInventoryWorking)
{[/INDENT]
[INDENT=3]UE_LOG(LogTemp, Warning, TEXT(“Error - GetAllItems() failed, inventory probably unavailable.”));[/INDENT]
[INDENT=2]}
else
{[/INDENT]
[INDENT=3]UE_LOG(LogTemp, Warning, TEXT(“GetAllItems() Called with Success.”));[/INDENT]
[INDENT=2]}[/INDENT]
}

}

//

and with logs i know that SteamAPI_Init() is being called with success, but when SteamInventory()->GetAllItems() is called the game crashes.

Here is the error that i get when the game crashes:

Do someone know what is happening?

For anyone that could have this same issue someday.

After searching a lot i discovered that probably is a pointer error. I am not sure if that is my case, but seems like it is. Check this post:
