TypeError: Cannot read property 'highest' of undefined - Mute Command

Question

嘿 Whosebug 社区，我有点困惑为什么它突然停止工作，我得到了标题中所述的错误。

基本上它会检查试图将某个用户静音的用户是否比其他用户具有更高的角色，如果他们这样做了..它会把他们静音，如果他们没有，它会抛出一个错误。

但现在它所做的只是再次抛出标题中所述的错误，我在文档中找不到修复方法？

此外，当我从支票中删除 highest.position 时，它允许任何拥有正确权限的人将高于或低于他们的任何人静音。

所以我在这里，很好地询问一些 help/understanding 为什么这种使用户静音的方法意外停止工作。

问题是 message.author returns a User 和 Users 没有角色；只有 GuildMember 有。 User 是 Discord 上的全局用户，而 GuildMember 是特定服务器上的用户，并且该成员在该服务器上具有角色。

因此，您应该使用 message.member that returns a GuildMember:

而不是 message.author

if (message.member.roles.highest.position <= mutedMember.roles.highest.position)
  return message.reply(
    "<a:CL_No:909440866622517318> You cannot mute that user because they have the same or higher role than you."
  );
