for...of 循环无缘无故停止

Question

我在 Discord 机器人上有以下 setInterval 运行：

client.setInterval(async () => {
    try {
        const response = await fetch('http://pso2.kaze.rip/eq/');
        if (response.status !== 200) return;

        const data = await response.json();
        const cache = JSON.parse(await fs.readFile("./cache.json"));

        if (data[0]["time"] !== cache["time"]) {
            const guilds = client.guilds.filter(guild => { return client.provider.get(guild, "alerts") });

            let i = 0;
            for (let guild of guilds) {
                i = i + 1;
                let settings = await client.provider.get(guild[1], "alerts");
                let eqs = data[0]["eqs"].filter(item => { return settings["ships"].includes(item["ship"]) });
                let format = [];

                if (!client.channels.get(settings['channel'])) return;
                let channel = client.channels.get(settings['channel']);

                if (eqs.length <= 0) return;
                if (eqs.length > 0 && eqs.length !== 10) {
                    for (let eq of eqs) {
                        format.push(`\`SHIP ${eq['ship']}:\` ${eq['name']} (${eq['jpName']})`);
                    }
                }
                else {
                    format.push(`\`ALL SHIPS:\` ${eqs[0]['name']} (${eqs[0]['jpName']})`);
                }

                let time = moment(data[0]["when"]);
                let string = `:watch:**IN 40 MINUTES:** (${time.format("HH:mm")} JST)\n${format.join('\n')}`;

                if (channel.type == "text" && channel.permissionsFor(client.user).has("SEND_MESSAGES")) {
                    //await client.channels.get(settings['channel']).send(string);
                    console.log(`${i} Sending alert to guild ${guild[1]}`);
                }
                else {
                    console.log(`${i} Skipping guild ${guild[1]}`);
                }
            }

            console.log('writing file...');
            await fs.writeFile("cache.json", `{ "time" : "${data[0]["time"]}" }`);
            console.log('done');
        }
    } catch (err) {
        console.error(err);
    }
}, 10000, client);

一切都按预期工作，除了在第 93 次迭代后循环停止并且没有执行任何其他操作（直到 setInterval 的下一次迭代发生）。这很奇怪，因为 guilds 数组中有超过 400 个对象，我什至检查了第 94 个元素以了解我在循环中所做的检查，并且它通过了所有这些检查。可能是什么原因造成的？

Answer 1

如果循环比行

退出

if (!client.channels.get(settings['channel'])) return;

是运行。

所以我猜您想继续循环，所以您应该使用 continue 退出该迭代，而不是 return
