javascript - 我该如何处理错误，忽略它并继续使用该功能？不和谐.js

Question

我正在尝试与我所有的 friend 在我的私有(private)服务器中对所有用户进行 dm，但是他们中的一些人不想被 dmed，所以他们关闭了他们的 dms。因此，我收到一个错误，该错误会阻止机器人继续访问其他用户。发现错误后如何跳过该用户并告诉我的机器人在之后继续 dm 下一个用户。

这是我的代码

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

class DMallCommand extends commando.Command {
    constructor(client){
        super(client, {
            name: `dmall`,
            group: 'dms',
            memberName: 'dmall',
            description: 'Sends message provided to all members of the guild.',
            examples: [ `${config.prefix}dmall Hey everyone! This might reach more people than a mass ping...` ]
        });
    }

    async run(message, args){
        let dmGuild = message.guild;
        let role = message.mentions.roles.first();
        var msg = message.content;


        try {
            msg = msg.substring(msg.indexOf("dmall") + 5);
        } catch(error) {
            console.log(error);
            return;
        }

        if(!msg || msg.length <= 1) {
            const embed = new Discord.RichEmbed()
                .addField(":x: Failed to send", "Message not specified")
                .addField(":eyes: Listen up!", "Every character past the command will be sent,\nand apparently there was nothing to send.");
            message.channel.send({ embed: embed });
            return;
        }

        let memberarray = dmGuild.members.array();
        let membercount = memberarray.length;
        let botcount = 0;
        let successcount = 0;
        console.log(`Responding to ${message.author.username} :  Sending message to all ${membercount} members of ${dmGuild.name}.`)
        for (var i = 0; i < membercount; i++) {
            let member = memberarray[i];
            if (member.user.bot) {
                console.log(`Skipping bot with name ${member.user.username}`)
                botcount++;
                continue
            }
            let timeout = Math.floor((Math.random() * (config.wait - 0.01)) * 1000) + 10;
            await sleep(timeout);
            if(i == (membercount-1)) {
                console.log(`Waited ${timeout}ms.\t\\/\tDMing ${member.user.username}`);
            } else {
                console.log(`Waited ${timeout}ms.\t|${i + 1}|\tDMing ${member.user.username}`);
            }
            try {
                member.send(`${msg} \n #${timeout}`);
                successcount++;
            } catch (error) {
                console.log(`Failed to send DM! ` + error)

            }
        }
        console.log(`Sent ${successcount} ${(successcount != 1 ? `messages` : `message`)} successfully, ` +
            `${botcount} ${(botcount != 1 ? `bots were` : `bot was`)} skipped.`);
    }
}

function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}

module.exports = DMallCommand;

我知道我没有处理任何错误，但我不知道该怎么做，真的可以使用一些帮助

这也是我的 bot.js 代码

  const Discord = require('discord.js');
const figlet = require('figlet');
const colors = require('colors');
const readline = require('readline');
const commando = require(`discord.js-commando`);

const config = require('./config.json');
const bot = new commando.Client({
    commandPrefix:'£',
    owner: config.id
});

const cmdsArray = [
    "dmall <message>",
    "dmrole <role> <message>"
];

bot.on("ready", () => {
    clear();
    console.log('______')
    bot.user.setActivity('PRDX');
});


bot.on("error", (error) => {
    bot.login(config.token);
});

bot.registry.registerGroup('dms', 'help');
bot.registry.registerDefaults();
bot.registry.registerCommandsIn(__dirname + "/commands");

if (process.env.BOT_TOKEN) bot.login(process.env.BOT_TOKEN);
else bot.login(config.token);
}

代码中的任何地方都使用错误事件监听器client.on("error", () => { client.login(token) });
