无法读取未定义的属性“通道”|不和谐

Question

一旦按下反应，机器人应该在某个类别中创建一个新的文本聊天。但这里是代码：

bot.on("messageReactionAdd", async (reaction, user) => {
      if(user.bot) return;
      if (reaction.message.partial) await reaction.message.fetch();
      if (reaction.partial) await reaction.fetch();
      
      if (user.bot) return; // If the user was a bot, return.
      if (!reaction.message.guild) return; 
      if (reaction.message.guild.id !== "601109434197868574") return; 
  
      if (reaction.emoji.name === "????") {
        let channel = await reaction.guild.channels.create(`ticket-${user.username}-#${user.discriminator}`); 
#${user.discriminator}`); 
}})

我收到以下错误：

你有一个错字。改变这个

if (reaction.emoji.name === "?") {
        let channel = await reaction.guild.channels.create(`ticket-${user.username}-#${user.discriminator}`); 
#${user.discriminator}`); 
}

到这里

    if (reaction.emoji.name === "?") {
        let channel = await reaction.message.guild.channels.create(
            `ticket-${user.username}-#${user.discriminator}`
        ); 
    }
