Some issue with the code that doesn't allow the creation of slash command error code 400

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

const BOT_TOKEN = 'YOUR_BOT_TOKEN';

const commands = [
    {
        name: 'ping',
        description: 'Ping pong!',
        options: [
            {
                name: 'secret',
                description: 'Secret code',
                type: 'STRING',
                required: true,
            },
        ],
    },
];

client.once('ready', async () => {
    console.log(`Logged in as ${client.user.tag}!`);

    // Register slash commands globally
    const application = await client.application.fetch();
    await application.commands.set(commands);
});

client.on('interactionCreate', async (interaction) => {
    if (!interaction.isCommand()) return;

    const { commandName, options } = interaction;

    if (commandName === 'ping') {
        const secretOption = options.getString('secret');

        if (secretOption === 'secretcode') {
            await interaction.reply('Pong!');
        } else {
            await interaction.reply('Bong!');
        }
    }
});

client.login(BOT_TOKEN);
