discord.py 错误处理无法正常工作

Question

我有自己的错误处理代码，我尝试当用户没有禁止/踢等人的权限时，它会发送错误并说明缺少什么权限。现在，它只说

Application did not respond

（我使用@client.tree.commands）。如何让它发送错误信息？这是我的错误处理代码：

@client.event
async def on_command_error(ctx, error):
    if isinstance(error, commands.errors.CommandNotFound):
        return
    elif isinstance(error, commands.MissingRequiredArgument):
        return
    elif isinstance(error, commands.errors.MissingPermissions) or isinstance(error, discord.Forbidden):
        required_permission = error.missing_perms[0] if isinstance(error, commands.MissingPermissions) else "Unknown Permission"
        noperms = discord.Embed(title="<a:wrong:1199385940263706765> ERROR",
                      description=f"```\nNO PERMISSIONS TO USE THIS COMMAND\n```\n**REQUIRED PERMISSIONS:**\n```\n{required_permission}\n```",
                      colour=0xf50000)
        await ctx.send(embed=noperms)
    elif isinstance(error, commands.errors.CommandOnCooldown):
        cooldown = discord.Embed(title="<a:wrong:1199385940263706765> ERROR",
                      description=f"```\nYOU NEED TO WAIT {error.retry_after:.2f} BEFORE TRYING THIS COMMAND AGAIN.\n```",
                      colour=0xf50000)
        await interaction.response.send_message(embed=cooldown)
    elif isinstance(error, commands.errors.MissingRole):
        if ctx.command.name in [""]:
            await ctx.send("You need premium to use this command")
    else:
        error = discord.Embed(title="<a:wrong:1199385940263706765> ERROR",
                      description=f"**SOMETHING WEIRD HAPPENED!?**\n__**SEND THIS ERROR CODE TO BOT DEVELOPERS:**__\n\n```\n{error}\n```",
                      colour=0xf50000)
        await ctx.send(embed=error)

我的朋友尝试在没有权限的情况下使用它，它应该发送带有权限的错误消息朋友需要使用它

on_command_error

是正常命令的事件，而不是斜杠命令。

要为应用程序（斜杠）命令创建全局错误处理程序，请使用

tree.error

装饰器：

from discord import app_commands, Interaction

tree = client.tree

@tree.error
async def on_app_command_error(
    interaction: Interaction,
    error: app_commands.AppCommandError
):
    if isinstance(error, app_commands.MissingPermissions):
        ...  # missing perms
    elif isinstance(error, app_commands.MissingRole):
        ...  # missing role
    elif isinstance(error, app_commands.CommandOnCooldown):
        ...  # command on cooldown
