Сan I get weapons that are removed from creative mode (for example, items from Marvel)?

I saw a videos where people took a spawner of items and added an item by code (https://pastebin.com/raw/dkJZQaTR). But I get an error. Can you help with it or show another solution?

BUG:

You’re not allowed to put Marvel items by code in your Fortnite island. Epic Games wouldn’t want you to try to put weapons in Creative mode that’s not supposed to be in Creative.
