AttributeError：“用户”对象没有属性“remove_roles”

我刚刚制作了一个应用代码的系统，但由于某种原因，剥夺用户的角色不起作用。如果我把要发送的消息放在前面，它就会发送，但错误仍然存​​在。

async def check_json():
    while True:
        with open("premium.json", "r") as f:
            data = json.load(f)

            if data["claimers"] != {}:
                for user in data["claimers"]:
                    if time.time() > data["claimers"][user]:
                        del data["claimers"][user]

                        member = await bot.get_or_fetch_user(user)
                        guild = bot.get_guild(1155525773424345151)
                        role = guild.get_role(1186708852767461416)

                        await member.remove_roles(role)
                        
                        await member.send(f"Hey! Your premium just expired. Thanks for using it :P")

                        with open("premium.json", "w") as f:
                            json.dump(data, f, indent=4)
        f.close()

        await asyncio.sleep(3)

抱歉，如果这个问题很愚蠢。我只是不明白错误是什么。感谢您的时间！

根据@Alpensin 的要求：
