Discord.js Error: EISDIR: illegal operation on a directory, read

Question

When i try executing this code i get an error. "Error: EISDIR: illegal operation on a directory, read".

Line 18: Column 19

const { Client, Intents, Collection } = require('discord.js')

const config = require('./config.json')

const fs = require('fs')

const bot = new Client({ intents: [ Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES ] })

bot.commands = new Collection()

var cmdFiles = fs.readFileSync('./cmd').filter(f => f.endsWith(".js"))

for(const f in cmdFiles) {
    const cmd = require(`./commands/${f}`)

    bot.commands.set(cmd.help.name, cmd)
}

bot.once("ready", () => {
    console.log('Bot is ready!')
})

bot.on("messageCreate", async message => {
    if(message.author.bot) return;

    var prefix = config.prefix

    if(!message.content.startsWith(prefix)) return;

    var array = message.content.split(" ");

    var command = array[0];

    const data = bot.commands.get(command.slice(prefix.length))

    if(!data) return;

    var args = array.slice(1)

    try {
        await data.run(bot, message, args)
    } catch(e) {
        await message.channel.send(e)
        await console.log(e)
    }
})

bot.login(config.token)

Yes all config things are defined. I've tried searching for this error but got nothing that i need.

What i want to do is load every file from the directory 'cmd' in a array list and run a command if it is called.

Change this:

var cmdFiles = fs.readFileSync('./cmd').filter(f => f.endsWith(".js"));

to this:

var cmdFiles = fs.readdirSync('./cmd').filter(f => f.endsWith(".js"));

As your question states, ./cmd is a directory and you can't list the files in a directory with fs.readFileSync() . You would use fs.readdirSync() to do that.

fs.readFileSync() tries to open the directory as a file and read its contents. Since it's not a file, you get the EISDIR error.
