如何解决channel.type.toUpperCase 不是函数 (discord.js/src/client/actions/ChannelUpdate.js:15)？

我运行 discord bot 并收到错误消息（尚未命令 bot 执行任何操作）。机器人自动崩溃

discord.js v12

我很少遇到这个错误。这是模块的错还是我的程序的错？如果是我的程序错误，我该如何解决？

在加载的第一个 .js 文件中，我看到有 1 个与 channel.type 相关的代码：

client.on("message",async message => {
    if(message.author.bot) return;
    if(message.channel.type --- ''dm'') return;
    if(message.content.startsWith(prefix)) {
        const args = message.content.slice(prefix.length).trim().split(/ +/);
        const command = args.shift().toLowerCase();
        
        if(!client.commands.has(command)) return;

        try {
            client.commands.get(command).run(client,message,args);
            
        } catch (error){ 
            console.error(error);
        }
    }
});

ChannelUpdate.js :

''use strict'';

const Action = require(''./Action'');
const Channel = require(''../../structures/Channel'');
const { ChannelTypes } = require(''../../util/Constants'');

class ChannelUpdateAction extends Action {
  handle(data) {
    const client = this.client;

    let channel = client.channels.cache.get(data.id);
    if (channel) {
      const old = channel._update(data);

      if (ChannelTypes[channel.type.toupperCase()] !== data.type) {
        const newChannel = Channel.create(this.client,data,channel.guild);
        for (const [id,message] of channel.messages.cache) newChannel.messages.cache.set(id,message);
        newChannel._typing = new Map(channel._typing);
        channel = newChannel;
        this.client.channels.cache.set(channel.id,channel);
      }

      return {
        old,updated: channel,};
    }

    return {};
  }
}

module.exports = ChannelUpdateAction;
