TypeError: 'NoneType' object is not subscriptable discord.py

Я сделал экономику в боте и сделал команду inventory(i) но при её вызове у меня появляется ошибка:

Traceback (most recent call last):
  File "C:\Users\fun\VirtualEnvDs\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\fun\PycharmProjects\ds_bot\Cogs\polina_shop.py", line 309, in inventory
    embed.add_field(name=fg[2], value=f"{x[1]}", inline=False)
TypeError: 'NoneType' object is not subscriptable
Command raised an exception: TypeError: 'NoneType' object is not subscriptable

Я нашёл бэкапы кода но это не помогло. Код самой команды inventory:

@commands.command(aliases=["i"])
    @cooldown(1, 2, BucketType.user)

        if page > 5 or page < 1:
            await ctx.send("Page must be between 1 and 5")
            return
        bal = await ecomoney.find_one({"id": ctx.author.id})
        if bal is None:

        intial, final = page_dict[page].split('-')
        for x in bag['bag']:
            total += 1
        if total == 0:
            await ctx.send("Your bag is empty")
            return

        page_items = bag['bag'][int(intial):int(final) + 1]

        embed = discord.Embed(

            embed.add_field(name=fg[2], value=f"{x[1]}", inline=False)

        embed.set_footer(
