[MCPE-161672] [GameTest] .setlore and .nameTag dont work for ItemStack Class

When I try to use .setLore() and .nameTag to set the lore of an item or change the itemname it doesn't work

import { world, ItemType, ItemStack, Items } from "mojang-minecraft";
let container = player.getComponent('minecraft:inventory').container
let itemSlot = player.selectedSlot
let itemLore; try {itemLore = container.getItem(itemSlot).getLore()} catch (e) {}
let itemName; try {itemName = container.getItem(itemSlot).nameTag} catch (e) {}
let itemCount; try {itemCount = container.getItem(itemSlot).amount} catch (e) {}
let itemData; try {itemData = container.getItem(itemSlot).data} catch (e) {}
let itemID; try {itemID = container.getItem(itemSlot).id} catch (e) {}
container.setItem(itemSlot, new ItemStack(Items.get(itemID), itemCount, itemData).setLore(['Test'])) // * || This throws an error: Unexpected type passed to function argument [0].
container.getItem(itemSlot).setLore(['Test']) // * || This doesn't throw an error

*Both methods don't work
