我正在尝试使用pycord创建一个discord bot。我有一个视图类如下：

class MyView(discord.ui.View):
    def __init__(self, link):
        self.link = link

    @discord.ui.button(label='480p', style=discord.ButtonStyle.gray, emoji='🎥')
    async def button_callback_480(self, button, interaction):
        button.disable = True
        await MyView.video_finder()

        await interaction.response.send_message('downloading the file. Check the server for file')
        await interaction.followup.send('follow up added to the queue')

    @discord.ui.button(label='720p', style=discord.ButtonStyle.danger, emoji='🎥')
    async def button_callback_720(self, button, interaction):
        button.disable = True
        await interaction.response.send_message('downloading the file. Check the server for file')
        await interaction.followup.send('follow up added to the queue')

使用上面的类，我创建了一个斜杠命令。斜杠命令的代码如下：

@bot.command(description="Choose the quality of video you want to download")
async def ytdl(ctx, link: str):

    view = MyView(link)
    await ctx.respond('Choose the quality of video you want to download', view = view)

如果我将link作为参数传递给类，则会得到以下错误：我也没有得到按钮渲染太多。

Ignoring exception in command ytdl:

The above exception was the direct cause of the following exception:

如果我不通过论证“链接”，它的工作完美。
