Cannot reproduce:

Code

import { Client, Events, version } from "discord.js";

const client = new Client({ intents: [] });

client.on(Events.ClientReady, () => {
	console.log(version);
	console.log(`Logged in as ${client.user?.tag}!`);
});

void client.login();

I noticed you're using Node.js 23, which is end of life (you should ideally not be using odd numbers of Node.js versions anyway). Can you try with Node.js 22 or 24?

Are you sure your bot is not located on any server?

[monbrey]

If your bot is not in any server, have you created a bot user for it at all? Or is it a slash command only application? If so, this is the expected behaviour. client.user should be null.

Bot user is created

[Jiralite]

Apologies, I missed over that detail! Seems I can reproduce.

I also mentioned that the client is missing "application"
