client.commands.set(command.data.name, command);

[dwstein]

I'm going through the guide for Discord.js and I've run into a couple of problems. I've had to convert require() into import in a couple of places, which has at least stopped these errors: ReferenceError: require is not defined in ES module scope, you can use import instead.

Now, however, I'm getting the following error: TypeError: Cannot read properties of undefined (reading 'name'). The line getting called is: client.commands.set(command.data.name, command);

I'm not sure what to do here. Any help appreciated.

Here is my full code for index.js:

import dotenv  from "dotenv";
dotenv.config();
const token = process.env.DTOKEN;

// const fs = require('node:fs');
import fs from 'node:fs';


// https://bobbyhadz.com/blog/javascript-dirname-is-not-defined-in-es-module-scope
import {fileURLToPath} from 'url';
const __filename = fileURLToPath(import.meta.url);
console.log(import.meta.url);

// const path = require('node:path');
import path from 'node:path';
// import path from 'path'
const __dirname = path.dirname(__filename);


// Require the necessary discord.js classes
import { Client, Collection, Intents } from "discord.js";
// const { token } = require('./config.json');

// Create a new client instance
const client = new Client({ intents: [Intents.FLAGS.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);
    const command = import(filePath);
	// Set a new item in the Collection
	// With the key as the command name and the value as the exported module
	client.commands.set(command.data.name, command);
}

// When the client is ready, run this code (only once)
client.once('ready', () => {
	console.log('Ready!');
});


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

	const { commandName } = interaction;

    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 });
	}
});

// Login to Discord with your client's token
client.login(token);

you have a file without the data export, maybe it's an empty file, who knows

Thank you for the response. Would you mind providing a bit more info? What is the data export?

[megatank58]

The guide exports a data object from all files in the commands folder, this is the JSON object from SlashCommandBuilder which is used to register the commands to the discord api, here it seems that the data object is not exported by one of your files, this can generally happen in case you have empty files or the exported variable is named something else.

Thank you!
