Discord Webhooks 频道返回未定义

Question

我是使用 webhook 的新手，我仔细阅读了 discord 文档以帮助我设置一个非常基本的机器人。在这一点上，我想做的就是让机器人上线并使用 webhook 发布帖子。我什至直接从 Discord Webhooks 文档中复制了基本代码，但我无法让它工作。

使用一些控制台日志，我确定 client.channels.cache.get(config.webhookID);返回未定义，因此 channel.fetchWebhooks() 不是函数。这仍然是获取频道中 webhook 的方法还是背后的文档？

我正在求助任何有经验的用户，他们可能会帮助我解决这个问题。如果您能提供任何帮助，我将不胜感激。

const Discord = require('discord.js');
const config = require('./config.json');

const client = new Discord.Client();

const embed = new Discord.MessageEmbed()
    .setTitle('Some Title')
    .setColor('#0099ff');

client.once('ready', async () => {
    const channel = client.channels.cache.get(config.webhookID); //This is the problem.
    try {
        const webhooks = await channel.fetchWebhooks(); //This will not execute because channel is undefined.
        const webhook = webhooks.first();

        await webhook.send('Webhook test', {
            username: 'some-username',
            avatarURL: 'https://i.imgur.com/wSTFkRM.png',
            embeds: [embed],
        });
    } catch (error) {
        console.error('Error trying to send: ', error);
    }
});

client.login(config.token);

控制台中的错误是这样的：

我想出了答案。我应该使用字段“channel_id”时使用了字段“id”。
