TypeError：无法读取未定义的属性(读取&#39；频道&#39；) [英] TypeError: Cannot read properties of undefined (reading 'channels')

问题描述

我遇到了这个小问题，我收到了未定义错误的Cannot Read属性，但我不知道问题出在哪里。有人能帮我搬这个吗？

代码如下：

const { Client } = require("discord.js");
const DB = require("../Structures/Schemas/LockDown");
/**
 * @param {Client} client
 */
module.exports = async(client) => {
    DB.find().then(async (documentsArray) => {
        documentsArray.forEach(async (d) => {
            const Channel = client.guilds.cache
            .get(d.GuildId)
            .channels.cache.get(d.ChannelID);
            if(!Channel) return;

            const TimeNow = Date.now();
            if(d.Time < TimeNow){
            Channel.permissionOverwrites.edit(d.GuildID, {
                SEND_MESSAGES: null,
            });
            return await DB.deleteOne({ ChannelID: Channel.id });
        }

            const ExpireDate = d.time - Date.now();

            setTimeout(async () => {
                Channel.permissionOverwrites.edit(d.GuildID, {
                    SEND_MESSAGES: null,
                });
                await DB.deleteOne({ ChannelID: Channel.id });
            }, ExpireDate);
        });
    });
};

下面是我收到的错误：

TypeError: Cannot read properties of undefined (reading 'channels')

推荐答案

可能并非所有渠道和行会都添加到缓存中。先试着把它们拿来，然后再看看。例如，下面这样的代码应该可以工作：

const { Client } = require('discord.js');
const DB = require('../Structures/Schemas/LockDown');
/**
 * @param {Client} client
 */
module.exports = async(client) => {
    DB.find().then(async(documentsArray) => {
        documentsArray.forEach(async(d) => {
            const GuildChannel = await client.guilds.fetch(d.GuildId);
            const Channel = await GuildChannel.channels.fetch(d.ChannelID);
            if (!Channel) return;

            const TimeNow = Date.now();
            if (d.Time < TimeNow) {
                Channel.permissionOverwrites.edit(d.GuildID, {
                    SEND_MESSAGES: null,
                });
                return await DB.deleteOne({
                    ChannelID: Channel.id
                });
            }

            const ExpireDate = d.time - Date.now();

            setTimeout(async() => {
                Channel.permissionOverwrites.edit(d.GuildID, {
                    SEND_MESSAGES: null,
                });
                await DB.deleteOne({
                    ChannelID: Channel.id
                });
            }, ExpireDate);
        });
    });
};

不是先获取行会然后获取渠道，而是直接从客户端获取渠道，如下所示：

const { Client } = require('discord.js');
const DB = require('../Structures/Schemas/LockDown');
/**
 * @param {Client} client
 */
module.exports = async(client) => {
    DB.find().then(async(documentsArray) => {
        documentsArray.forEach(async(d) => {
            const Channel = await client.channels.fetch(d.ChannelID);
            if (!Channel) return;

            const TimeNow = Date.now();
            if (d.Time < TimeNow) {
                Channel.permissionOverwrites.edit(d.GuildID, {
                    SEND_MESSAGES: null,
                });
                return await DB.deleteOne({
                    ChannelID: Channel.id
                });
            }

            const ExpireDate = d.time - Date.now();

            setTimeout(async() => {
                Channel.permissionOverwrites.edit(d.GuildID, {
                    SEND_MESSAGES: null,
                });
                await DB.deleteOne({
                    ChannelID: Channel.id
                });
            }, ExpireDate);
        });
    });
};

或者，如@Malik Lahlou所说，可能是打字错误。

资源：

• ChannelManager.fetch()
• GuildManager.fetch()
