discord.js - Bot sending messages twice

Question

My discord bot keeps sending messages twice, as shown in this image.

Here's the simplified code for index.js:

const { prefix, token, giphyToken } = require('./config.json');
const fs = require('fs')
const Discord = require('discord.js');
const client = new Discord.Client();
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

var GphApiClient = require('giphy-js-sdk-core')
giphy = GphApiClient(giphyToken)

client.once('ready', () => {
    console.log('Ready!');

});


for (const file of commandFiles) {
    const command = require(`./commands/${file}`);
    client.commands.set(command.name, command);
}

client.on('message', message => {

    if (!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();

    if (!client.commands.has(command)) return;

    try {
        client.commands.get(command).execute(message, args);
    } catch (error) {
        console.error(error);
        message.reply('there was an error trying to execute that command!');
    }
})
client.login(token);

I even tried changing the token multiple times and I killed the terminal to get rid of multiple instances, but nothing prevailed. What can I do to fix this?

Answer 1

I actually figured out what was happening here, it was an issue with pm2.

Long story short, don't run pm2 and node . at the same time, that was what caused this issue.
