Discord.py按钮向成员添加角色返回非类型错误

Question

我正在尝试使用discord.py模块的discord组件包制作一个按钮

我有以下代码：

@client.command()
async def button(ctx):
    await ctx.channel.send(
        "This is a button test",
        components = [
            Button(style=ButtonStyle.blue, label="Button 1")
        ]
    )


    res = await client.wait_for("button_click")
    if res.channel == ctx.channel:
        member = await res.guild.get_member(res.user.id)
        await member.add_role(853692936465940501)
        await res.respond(
            type=InteractionType.ChannelMessageWithSource,
            content=f"{res.component.label} has been clicked! This is button 1"
        )

但我似乎有问题，出错了

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: object NoneType can't be used in 'await' expression

为什么guild.get_成员返回非类型？ 有没有人可能有一些关于如何使用discord.py按钮实现角色更改的示例代码？因为我好像没法让它工作

谢谢：）

@client.command()
async def button(ctx):
    await ctx.channel.send(
        "This is a button test",
        components = [
            Button(style=ButtonStyle.blue, label="Button 1")
        ]
    )


    res = await client.wait_for("button_click")
    if res.channel == ctx.channel:
        role = discord.utils.get(ctx.guild.roles, id = 853692936465940501)
        await res.author.add_roles(role)
        await res.respond(
            type=4,
            content=f"{res.component.label} has been clicked! This is button 1"
        )
