Javascript 无法在获取的通道| Discord.js中发送消息

目的：向公会所有者发送消息，然后创建邀请，然后向指定频道发送邀请

代码

如果你的陈述是错误的：

if（！InviteLogGuild）{
控制台。错误（红色（`\n[未识别日志]\n`）
}else if（InviteLogGuild | | |！InviteLogChannel）{

这是错误的，它将始终输入此案例，因为您正在检查InviteLogGuild是否已定义或InviteLogChannel是否未定义。由于第一个案例已检查要定义的InviteLogGuild，因此将始终返回
true
。要使其正常工作，您必须将其更改为：

if（！InviteLogGuild）{
控制台。错误（红色（`\n[未识别日志]\n`）
}else if（InviteLogGuild&！InviteLogChannel）{

但是您可以完全删除
&&
，因为第一个案例已经检查了InviteLogGuild是否已定义：

if（！InviteLogGuild）{
控制台。错误（红色（`\n[未识别日志]\n`）
}如果（！InviteLogChannel）{

如果您将这些因素考虑在内，您的最终“如果链”将如下所示（并且有效）：

if（！InviteLogGuild）{
console.error（红色（`\n[LOG GUILD NOT IDENTIFIED]\n`））；
}如果（！InviteLogChannel）{
console.error（红色（`\n[LOG GUILD IDENTIFIED | CHANNEL UNIDENTIFIED]\n`）；
}否则{
log（cyanBright（`[LOGGING INVITE]`））；
const LogChannel=new Discord.MessageEmbed（）
.setTitle（`New Guild Joined:`）
.setDescription（`**Guild Name:*${Guild.Name}\n\n**MemberCount:*${Guild.MemberCount}\n\n**Onwer:*\`${（wait fetchOwner）.tag}\`\n\n**邀请链接：*${（wait Link）.url}`）
.set缩略图（`${guild.iconURL（{dynamic:true}}）}`）；
InviteLogChannel.send（LogChannel）；
log（青色（`[INVITE LOGGED]\n`））；
}

为了避免此类问题，我建议您切换到使用TypeScript或开始使用ESLint，这会建议您进行不必要的检查

旧答案

尝试使用
guild.channels.resolve（channelId）
和
client.guilds.resolve（guildId）
而不是使用缓存。这可能是因为该频道尚未加载到缓存中，无法找到。
我不太清楚为什么这样做有效，但我从if语句中取出了我的消息commmand，它起了作用

    if (!InviteLogGuild) {
        return console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`));
    } else if (InviteLogGuild) {
        console.log(greenBright(`[LOG GUILD IDENTIFIED]`));
    } else if (!InviteLogChannel) {
        return console.error(red(`\n[LOG CHANNEL NOT PRESENT]\n`));
    } else if (InviteLogChannel) {
        console.log(cyanBright(`[LOG CHANNEL IDENTIFIED]`));
    } 

    console.log(cyanBright(`[LOGGING INVITE]`));
    const SendMessage = new Discord.MessageEmbed()
        .setTitle(`New Guild Joined:`)
        .setDescription(`**Guild Name:** ${guild.name} \n\n**MemberCount:** ${guild.memberCount} \n\n**Onwer:** \`${(await fetchOwner).tag}\` \n\n**Invite Link:** ${(await link).url}`)
        .setThumbnail(`${guild.iconURL({ dynamic: true })}`);
    InviteLogChannel.send(SendMessage);
    console.log(cyan(`[INVITE LOGGED]\n`));

结果：

[GUILD JOINED] Ghoulish Hangout | [ID] 618894612769275959 | [ (+) MEMBERCOUNT: 23]

[GUILD OWNER MESSAGED]
[CHANNEL FETCHED]

[LOG GUILD IDENTIFIED | CHANNEL UNIDENTIFIED] <---- Error

[GUILD JOINED] test | [ID] 2389372187328783 | [ (+) MEMBERCOUNT: 9]

如果有人能解释原因，请放心！
您确定ID正确吗？是的，我非常确定仍然会发生相同的错误。我尝试了不同的频道ID，但仍然是相同的错误；（查看我编辑的答案）
