Why do I get an error with slash commands?

[gamer167]

My code is:
Deploy:
const { REST, Routes } = require('discord.js');
const token = process.env['token'];
const clientId = process.env['clientId']
const guildId = process.env['guildId']
const fs = require('node:fs');

const commands = [];
// Grab all the command files from the commands directory you created earlier
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

// Grab the SlashCommandBuilder#toJSON() output of each command's data for deployment
for (const file of commandFiles) {
const command = require(./commands/${file});
commands.push(command.data.toJSON());
}

// Construct and prepare an instance of the REST module
const rest = new REST({ version: '10' }).setToken(token);

// and deploy your commands!
(async () => {
try {
console.log(Started refreshing ${commands.length} application (/) commands.);

	// The put method is used to fully refresh all commands in the guild with the current set
	const data = await rest.put(
		Routes.applicationGuildCommands(clientId, guildId),
		{ body: commands },
	);

	console.log(`Successfully reloaded ${data.length} application (/) commands.`);
} catch (error) {
	// And of course, make sure you catch and log any errors!
	console.error(error);
}

})();
Main code:
// COW Want to use evn thats built in?
const fs = require('node:fs');
const path = require('node:path');
const { Client, Collection, Events, GatewayIntentBits } = require('discord.js');
const token = process.env['token'];
const deploycommands = require('./deploy-commands.js');
const keepalive = require('./keepalive.js');

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

client.commands = new Collection();
const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
const filePath = path.join(commandsPath, file);
const command = require(filePath);
client.commands.set(command.data.name, command);
}

client.once(Events.ClientReady, () => {
console.log('Ready!');
});

client.on(Events.InteractionCreate, async interaction => {
if (!interaction.isChatInputCommand()) return;

const command = client.commands.get(interaction.commandName);

if (!command) return;

try {
	await command.execute(interaction);
} catch (error) {
	console.error(error);
	await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
}

});

client.login(token);

keepalive();

The command /ping worked until I added more commands.

Answer

After testing your issue it seems to work fine on my end. I assume it has to do something with your env declaration. Try changing your env into a ./config.json file like this if your just hosting the bot yourself. If your using a Host platform like render or heroku. Look at their env file docs.

{
    "token": "token-here",
    "clientId": "clientid-here",
    "guildId": "guildid-here",
}

Some Advice

Keepalive()

In your main code. Why do you exactly have

const keepalive = require('./keepalive.js');
// ...

keepalive();

Discord.js automatically keeps your bot alive as long as its being hosted on the server.

Use code blocks

when asking for help on anything code related. Use code blocks to make life easier for people trying to help you.

Example:

console.log
