Discord.js 在DM通道中等待消息

我正在尝试使用Discord.js在Discord上发布一个公告机器人，当有人键入-na it DM时，会给他们一个嵌入，然后接受他们的输入，生成一个变量作为他们的输入，然后进行几次该过程。我遇到的问题是，当我运行bot，然后执行命令-na时，它会给我一个错误，即：TypeError:cannotreadproperty'awaitMessages'的undefined。 这是我的密码：

const allyAnnouncementChannel = client.channels.cache.get('756701256122236941')

---

msg.member

返回一个对象。但是，该属性仅在上可用

msg.author.dmChannel.awaitMessages（…）//将'msg.member'更改为'msg.author'`

TypeError:无法读取null属性'waitMessages'，这是我执行命令时遇到的错误。您必须将

msg.member

替换为

msg.author

我将其更改为null，但它仍然给我该错误。

if (msg.content === '-na') {
        if (msg.channel === Discord.DMChannel) {
            return
            } else
            if (msg.member.roles.cache.has('756713479003701338')) {
                msg.author.send(Ping);

                msg.member.dmChannel.awaitMessages(m => m.author.id === msg.author.id,

                            msg.author.send(Title);
