为什么这会使机器人崩溃？

Question

bot.on('guildMemberAdd', member => {
    const welcomeembed = new Discord.RichEmbed()
            .setColor(0xfcdb03)
            .setTitle("Welcome")
            .addField("Welcome " + member + "** to our Discord Server!**", "Please verify yourself in " + message.guild.channels.get('723965000062074990'))
    member.guild.channels.get('723240170329079870').sendEmbed(welcomeembed); 
});

当我使用常规消息时，机器人不会崩溃。也许我只是使用错误的嵌入消息。

    Object.defineProperty(this, 'client', { value: message.client });
                                                           ^

TypeError: Cannot read property 'client' of undefined

您需要设置您的环境，以便您可以看到错误。否则，你怎么能指望能够解决你遇到的任何问题？如果您使用批处理文件或类似文件启动机器人，请对其进行编辑并在新行中添加 PAUSE 以强制窗口在进程终止后保持打开状态。否则，您可以尝试让节点处理输出到文件 - 查找执行此操作的方法。

问题可能与message.guild.channels.get('723965000062074990') 有关。没有message，您在guildMemberAdd 事件中。请改用member.guild。

bot.on('guildMemberAdd', member => {
  const welcomeembed = new Discord.RichEmbed()
    .setColor(0xfcdb03)
    .setTitle("Welcome")
    .addField("Welcome " + member + "** to our Discord Server!**", "Please verify yourself in " + member.guild.channels.get('723965000062074990'))
  member.guild.channels.get('723240170329079870').sendEmbed(welcomeembed); 
});
