下面的cron作业被设置为每分钟运行一次更新计时器，并且根据日志，当有人加入服务器时就会停止。它不会抛出任何错误代码。机器人不会崩溃。我希望有人能告诉我为什么要这么做。
这是cron作业：
cron.schedule('* * * * *', function () {
bot.channels.cache.filter((channel) => channel.name.endsWith('events')).forEach((channel) => {
channel.messages.fetch({
limit: 100
}).then(messages => {
messages.forEach(message => {
if (message.embeds.length > 0) {
const embed = message.embeds[0]
let messageID;
let event_date;
let event_time;
if (embed.color === 65280) {
messageID = message.id
event_date = message.embeds[0].fields[0].value
event_time = message.embeds[0].fields[1].value.slice(0, -4)
let now = Date.now()
const targetDate = new Date(`${event_date} ${event_time}:00`)
var difference = (targetDate - now) / 1000;
var days = Math.floor(difference / (3600 * 24));
var hours = Math.floor((difference - (days * (3600 * 24))) / 3600);
var minutes = Math.floor((difference - (days * (3600 * 24)) - (hours * 3600)) / 60);
let timeTill;
if (days > 0) {
timeTill = `${days} Days ${hours} Hours ${minutes} Min`
} else if (days === 0 && hours > 0) {
timeTill = `${hours} Hours ${minutes} Min`
} else if (days === 0 && hours === 0) {
timeTill = `${minutes} Min`
} else if (difference <= 0) {
timeTill = `Event Started - get with <@!${row.hostID}> to join up in-game.`
}
embed.fields[9] = {
name: 'Starts in:',
value: `${timeTill}`,
inline: false
}
message.edit(new Discord.MessageEmbed(embed)).catch(error => {
console.error(error);
})
console.log(`Event ${message.embeds[0].author.name} has been edited. New start time is ${timeTill}.`)
} else {
return
}
} else {
return
}
})
})
})
})
以下是当有人加入时停止的日志

不确定原因，但上面的注释解决了问题。
