Why is my Discord bot not working on Node.js?

const { Client, GatewayIntentBits } = require('discord.js');

const bot = new Client({
    intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages,]
});
const prefix = "!";

bot.on('ready', async () => {
    console.log(`${bot.user.username} запустился`)
});

bot.on("messageCreate", function(message) {
    if (message.author.bot) return;
    if (!message.content.startsWith(prefix)) return;
  
    const commandBody = message.content.slice(prefix.length);
    const args = commandBody.split(' ');
    const command = args.shift().toLowerCase();

    if (command === "ping") {
      const timeTaken = Date.now() - message.createdTimestamp;
      message.reply(`Pong! This message had a latency of ${timeTaken}ms.`);
    }
  
    else if (command === "sum") {
      const numArgs = args.map(x => parseFloat(x));
      const sum = numArgs.reduce((counter, x) => counter += x);
      message.reply(`The sum of all the arguments you provided is ${sum}!`);
    }
});

bot.login('');
