“应用程序没有响应”。为什么会出现这种情况？

Question

每次我在 Discord 机器人上运行命令“purge”时，在命令运行并删除有限消息后，我总是看到“应用程序没有响应”。我正在使用discord.app_commands（我相信）和树作为我的命令，以便它们可以作为斜杠命令运行。

这是我的进口：

import discord
from discord import app_commands
from discord.ext import commands
from asyncio import sleep

命令如下：

@tree.command(
    name="purge",
    description="Deletes a specified number of messages from the channel."
)
async def purge(interaction, limit: int):
    try:
        if interaction.user.guild_permissions.manage_messages:
            await interaction.channel.purge(limit=limit + 1)
            await sleep(2)
            await interaction.response.send_message(f"{limit} messages deleted!", ephemeral=True)

        else:
            await interaction.response.send_message("You don't have permission to use this command.", ephemeral=True)
    except discord.errors.NotFound:
        # Handle the case where the interaction is not found
        await interaction.response.send_message("An error occurred while processing the command. Please try again later.", ephemeral=True)
    except discord.errors.Forbidden:
        # Handle the case where the bot doesn't have permission to perform the action
        await interaction.response.send_message("I don't have permission to perform this action.", ephemeral=True)
    except Exception as e:
        # Handle any other exceptions that might occur
        await interaction.response.send_message(f"An unexpected error occurred: {str(e)}", ephemeral=True)

仅当我运行清除时才会出现此错误，我没有使用其他命令导致此错误。我使用任何整数的限制块执行了“/purge”，并且在机器人删除特定数量的消息后，我预计它会显示“{limit}条消息已删除！”但相反，它显示“应用程序没有响应”。我尝试让机器人等待 2 秒再发送消息，但也不起作用。

此外，我的服务器控制台的回溯：

During handling of the above exception, another exception occurred:

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

您必须在功能开始时使用

interaction.defer()

，因为交互可以在3秒内回复，而清除则需要超过3秒。但使用

interaction.defer()

会将 3 秒限制增加到 15 分钟。

更新代码：

@tree.command(
    name="purge",
    description="Deletes a specified number of messages from the channel."
)
async def purge(interaction, limit: int):
    await interaction.defer() # here
    try:
        if interaction.user.guild_permissions.manage_messages:
            await interaction.channel.purge(limit=limit + 1)
            await sleep(2)
            await interaction.response.send_message(f"{limit} messages deleted!", ephemeral=True)

        else:
            await interaction.response.send_message("You don't have permission to use this command.", ephemeral=True)
    except discord.errors.NotFound:
        # Handle the case where the interaction is not found
        await interaction.response.send_message("An error occurred while processing the command. Please try again later.", ephemeral=True)
    except discord.errors.Forbidden:
        # Handle the case where the bot doesn't have permission to perform the action
        await interaction.response.send_message("I don't have permission to perform this action.", ephemeral=True)
    except Exception as e:
        # Handle any other exceptions that might occur
        await interaction.response.send_message(f"An unexpected error occurred: {str(e)}", ephemeral=True)
