I am getting this error on my discord bot

enter image description here

This is my code:

require('dotenv').config();
const { Client, Intents } = require('discord.js');

const client = new Client({
  intents: [
    Intents.FLAGS.Guilds,
    Intents.FLAGS.GuildMembers,
    Intents.FLAGS.GuildMessages,
    Intents.FLAGS.MessageContent,
  ],
});

client.on('ready', (c) => {
  console.log(`✅ ${c.user.tag} is online.`);
});

client.on('messageCreate', (message) => {
  if (message.author.bot) {
    return;
  }

  if (message.content === 'hello') {
    message.reply('hello');
  }
});

I tried to make a simple test command but when i try to run it , it gives me that error.
I dont understand what i did wrong, i followed a tutorial. But it works perfectly fine with ‘node .’but with nodemon it has that error
