Pycord斜杠命令在Discord中无响应的问题求助

正在开发一款支持玩家联机游戏的Discord机器人，使用Python 3.10.8和Pycord库，代码如下：

from dotenv import load_dotenv
load_dotenv()
import discord,os
global TOKEN,bot,main,games

TOKEN = os.getenv("DISCORD_TOKEN")
bot = discord.Bot()
main = bot.create_group("nisticks","Nisticks Commands")
games = main.create_subgroup("games","Nisticks Games Commands")

@games.command(description="Tic Tac Toe")
async def ttt(ctx):
    await ctx.respond("gg")


if __name__ == '__main__':
    bot.add_application_command(main)
    bot.run(TOKEN)

在Discord中执行斜杠命令/nisticks games ttt后无响应，Python控制台抛出以下错误：
