Cast error in UArticyIncomingConnection::GetSourcePin()

[lukemols]

Hi, I'm upgrading my project from UE5.3 to UE5.4 and I'm experiencing compile errors.
I'm using the latest version of Articy Importer (1.8.0).

At row 91 of ArticyBuiltinTypes.cpp (LINK) there is a cast to a UArticyOutputPin from a UArticyObject (return value of GetObject function).

UArticyOutputPin* UArticyIncomingConnection::GetSourcePin() const
{
	if(!SourcePinObj)
	{
		auto db = UArticyDatabase::Get(this);
		SourcePinObj = db ? Cast<UArticyOutputPin>(db->GetObject(SourcePin)) : nullptr;
	}

	return SourcePinObj;
}

This cannot never be true, since UArticyOutputPin doesn't not inherit from UArticyObject but from UArticyBaseObject.

Full inheritance path here:
UArticyOutputPin > UArticyFlowPin > UArticyPrimitive > UArticyBaseObject
UArticyObject > UArticyPrimitive > UArticyBaseObject

In UE5.4 the Cast function changed and added a compile time check that ensures that the classes are related (Link to UE commit), so now the plugin is no more compiling.

Before changing anything in my side, I opened this issue to ask what is the expected output of the function.
