async def accept(inter):
       whitlist_id = data[str(inter.guild.id)]["whitelist"]["active_whitelist"]
       whitlist = bot.get_user(whitlist_id)
       await inter.send(f"<@{whitlist_id}>, вы были приняты!")
       await whitlist.add_roles(1205097011892981811)
       await whitlist.remove_roles(1205235121494560768)
       del data[str(inter.guild.id)]["whitelist"]["active_whitelist"]
       save_db(data=data)

и в консоли выдаёт ошибку

    await whitlist.add_roles(1205097011892981811)
