Discord.py bot 不响应静音命令

Question

我正在尝试在 discord.py 中创建一个静音命令，一切似乎都是正确的。每当我使用该命令时，我的机器人都不会响应我给它的消息，也不会给出静音角色。代码如下：

@commands.has_permissions(manage_roles=True)
async def mute(ctx, user: discord.Member, *, reason="No reason provided"):
    await user.mute(reason=reason)
    role = discord.utils.get(ctx.guild.roles, name="Muted")
    mute = discord.Embed(title=f"User {user.name}#{user.discriminator} has been muted. <a:m_verifyblack:850825891780100096>", color=0xF4D03F, description=f"Reason: {reason}\nBy: {ctx.author.mention}")
    await ctx.message.delete()
    await ctx.channel.send(embed=mute)
    await user.send(embed=mute)
@mute.error
async def mute_error(ctx, error):
    if isinstance(error, commands.MissingPermissions):
        await ctx.send("**:no_entry_sign: You cant do that!**")```
