DiscordAPIError[0]: 401: Unauthorized

Question

When I try to run the command on the powershell termianl (node .\index.js\) I get the same error every time. I changed the token multiple times but still got the same error. I run the command on the right root directory, so I don't know what to do.

Code:

import { config } from 'dotenv';
import { Client, GatewayIntentBits, Routes } from 'discord.js';
import { REST } from '@discordjs/rest';

config();

const TOKEN = process.env.BOT_TOKEN_CLOUD;
const CLIENT_ID = process.env.CLIENT_ID;
const GUILD_ID = process.env.GUILD_ID;

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

const rest = new REST({ version: '10' }).setToken('TOKEN');

client.on('ready', () => {console.log(`${client.user.tag} has logged in!`);});

async function main() {
    const commands = [
        {
            name: 'testcommand',
            description: 'test command'
        },
    ];
    try {
        console.log('Started refreshing application (/) commands.');
        await rest.put(Routes.applicationGuildCommands(CLIENT_ID, GUILD_ID), {
            body: commands,
        });
        client.login(TOKEN);
    }   catch (err) {
        console.log(err);
    }
}

main();

Error:

You need to use the specific token for your bot instead of 'TOKEN' string

const rest = new REST({ version: '10' }).setToken('TOKEN'); here, .setToken() should be like .setToken(TOKEN)
