如何获取在discord.py中引发错误的命令的名称？

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.typing = False
intents.presences = False

bot = commands.Bot(command_prefix='!', intents=intents)

@bot.event
async def on_command_error(ctx, error):
    if isinstance(error, commands.CommandError):
        command_name = ctx.command.name
        await ctx.send(f"Error in command '{command_name}': {error}")

@bot.command()
async def hello(ctx):
    await ctx.send("Hello!")

bot.run('YOUR_BOT_TOKEN')
