Question

我的链接过滤器系统出现错误。某些角色无法正常工作。

这是我得到的错误：

因为 message.member 返回 GuildMember 在这种情况下没有成员。
那是什么意思？这意味着有人在私人聊天 (DM) 中向机器人发送了消息
要解决此问题，只需忽略不在服务器中的消息：
if(!message.guild) return; 所以你的代码将是这样的：\

//Linkfilter
bot.on("message", async message => {
    if(!message.guild) return;
    const mongo = require('./mongo')
    const warnSchema = require('./models/warn-schema')

discord.js Linkfilter TypeError：无法读取 null 的属性“角色”
