I am new to command handler I am trying to execute commands for different js file
but I get this error
TypeError: Cannot read property 'execute' of undefined
this is my main.js
// Import the discord.js module
const Discord = require('discord.js');
const fs = require('fs');
// Create an instance of a Discord client
const client = new Discord.Client();
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
const prefix = "$"
/**

client.on('ready', () => {
console.log('I am ready!');
});
client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'pingg'){
client.commands.get('pingg').execute(message, args);
}
if (!client.commands.has(command)) return;

} catch (error) {
console.error(error);
message.reply('there was an error trying to execute that command!');
}

fs.readdir("./commands/", (err, files) => {
if(err) console.error(error)
let jsfiles = files.filter(f => f.split(".").pop() === "js")
if (jsfiles.length <= 0) {
return console.log("No commands to log in FOLDER NAME")
}
console.log(`Loading ${jsfiles.length} commands from FOLDER NAME...`)
jsfiles.forEach((f,i) => {
let props = require(`./commands/${f}`)
console.log(`${i + 1}: ${f} loaded!`)
client.commands.set(f, props)
})
})
my ping.js
module.exports = {
name : 'pingg',
description : 'Test',
execute(message, args){
message.channel.send('pongg')
}
}
The commands are registered in client.commands collection in the bot application lifecycle after the client is ready.
This is because client.login is invoked before it.
You can use commandFiles to load the commands from their modules. This was already performed sychronously so you have some guarantee on the order.
Also do that before the client.login statement.
Another issue is that the command module is named ping.js and as such your current implementation registers ping command to client.command collection.
However, you are resolving pingg command from the collection which returns an undefined
commandFiles.forEach(file => {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
});
client.login('censored');

I am trying to make a discord bot with discordJS (v14) and I followed the tutorial from
https://discordjs.guide/creating-your-bot/slash-commands.html#individual-command-files and created a slash command. However, when I call the slash command, it always shoe DiscordAPIError[10062]: Unknown interaction I tried to use the command await interaction.deferReply() but it still failed.
Here are my code of that function
play.js
const { SlashCommandBuilder } = require("discord.js");
module.exports = {
data: new SlashCommandBuilder()
.setName("play")
.setDescription("Play the song from the url or search query")
.addStringOption(option =>
option.setName("query")
.setDescription("The url or search query")
.setRequired(true)
),
async execute(interaction) {
console.log("interaction received"); // This part can run
await interaction.deferReply()
console.log("play command executed"); // cannot run
await interaction.editReply({ content: interaction.options.getString("query"), ephemeral: true });

if ('data' in command && 'execute' in command) {
client.commands.set(command.data.name, command);
} else {

The terminal result shows that it received the message but it continue to have the error
DiscordAPIError[10062]: Unknown interaction
May I ask how can I solve the problem and why it would happen?
I'm trying to add a command code under the command file, but i'm unable to get it to work. The problem arises at this line => if (command == 'checkin' || command == 'ch') {
client.commands.get('chk').execute(message).
Without that line, the code works fine with the other 2 commands. I think it has to do with the async function but I'm not sure how to solve this problem. I don't want to include the whole chunk of code in the main file either, as it gets very long and cluttered. I'm new to coding, so it might be something I can't understand yet - please help me!
bot.js (the main .js file)
const { token, prefix } = require('./config.json');
const fs = require('fs');
const db = require('quick.db');
const ms = require('parse-ms-2')
const { Client, Intents, Message, Collection } = require("discord.js");
const client = new Client({
intents: [
Intents.FLAGS.GUILDS,
Intents.FLAGS.GUILD_MESSAGES
]
});
client.commands = new Discord.Collection();
// filter commands
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
// fetch commands
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.once("ready", () => {
console.log("online.");
client.user.setPresence({ activties: [{ name: 'with commands' }] });
})
client.on('messageCreate', async message => {
// definite command components
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase()
if (command == 'help' || command == 'h') {
client.commands.get('help').execute(message)
}
if (command == 'bal') {
client.commands.get('bal').execute(message)
}
if (command == 'checkin' || command == 'ch') {
client.commands.get('chk').execute(message)
}
})
client.login(token)
chk.js (where the command is)
const db = require('quick.db')
const nm = require('parse-ms-2')
module.exports = {
name: "check in",
descrption: "daily check in rewards.",
async execute(message) {
let user = message.mentions.users.first() || message.author;
let daily = await db.fetch(`daily_${message.author.id}`);
let money = db.fetch(`money_${user.id}`);
let cooldown = 1000*60*60*20
let amount = Math.floor(Math.random() * 500) + 250
if (daily != null && cooldown - (Date.now() - daily) > 0) {
let time = ms(cooldown - (Date.now() - daily));
message.channel.send(`You have already collected the daily check in reward, please check in again in **${time.hours}h ${time.minutes}m ${time.seconds}s**`)
} else {
let embed = new Discord.MessageEmbed()
.setTitle('Daily Check In')
.setDescription(`Here is the amount collected today: ${amount}`)
.setColor('#ffc300')
message.channel.send({embeds: [embed]})
db.add(`money_${message.author.id}`, amount)
db.add(`daily_${message.author.id}`, Date.now())
}

Cannot read property 'execute' of undefined"
Means client.commands.get('chk') is returning undefined.
Presumably, this means the chk command can't be found.
So, let's look at where you're setting the commands:
// fetch commands
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
And let's check your chk.js file which is being imported.
module.exports = {
name: "check in",
// ...
What I can see is, you're exporting the module and setting the command with the name "check in" but later in the script, you're asking for a command called "chk". The command can't be found, returns undefined, and kills your code as it isn't handled.
The solution in this case is to just change your name property to "chk", or request client.commands.get("check in") instead.
I want to change the icon of a specific guild that my bot is in. To do so, I need to use the guild.setIcon() method. I already have the guild's ID but I don't know how I should go about turning it into an object that I can use.
The guildId constant is stored as a string in config.json.
Here is my index.js, where I'm trying to run the code.
// Require the necessary discord.js classes
const { Client, Collection, Intents } = require("discord.js");
const { token, guildId } = require("./config.json");
const fs = require("fs");
// Create a new client instance
const client = new Client({ intents: [Intents.FLAGS.GUILDS] });
client.commands = new Collection();
const commandFiles = fs
.readdirSync("./commands")
.filter((file) => file.endsWith(".js"));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.data.name, command);
}
const eventFiles = fs
.readdirSync("./events")
.filter((file) => file.endsWith(".js"));
for (const file of eventFiles) {
const event = require(`./events/${file}`);
if (event.once) {
client.once(event.name, (...args) => event.execute(...args));
} else {
client.on(event.name, (...args) => event.execute(...args));
}
}
client.on("interactionCreate", async (interaction) => {
if (!interaction.isCommand()) return;
const command = client.commands.get(interaction.commandName);
if (!command) return;
try {
await command.execute(interaction);
} catch (error) {
console.error(error);
await interaction.reply({
content: "There was an error while executing this command!",
ephemeral: true,
});
}
});
client.login(token);
const myGuild = client.guilds.cache.get(guildId)
myGuild.setIcon("./images/image.png");
The error I get is
myGuild.setIcon("./images/image.png");
^
TypeError: Cannot read properties of undefined (reading 'setIcon')
You need to do this in an event. No guilds are cached until the client is ready
client.on("ready", async () => {
const myGuild = client.guilds.cache.get(guildId)
await myGuild.setIcon("./images/image.png")
})
Your issues comes from the fact that you're trying to get the guild from your bot cache, but he doesn't have it in it's cache
First, you have to wait for your bot to be successfully connected
Then, you're not supposed to read from the cache directly, use the GuildManager methods (here you need fetch)
to summarize, replace the 2 lasts lines of your index.js by
client.on("ready", async () => {
const myGuild = await client.guilds.fetch(guildId)
myGuild.setIcon("./images/image.png")
})
I have a command handler for my discord bot. It loads the command modules fine, (and console logs indicate as much), but I'm having trouble getting it to execute commands beyond the first command module. Here's the code:
const Discord = require("discord.js");
const client = new Discord.Client();
client.commands = new Discord.Collection();
const prefix = "f$";
const fs = require("fs");
try {
const files = fs.readdirSync("./commands/");
let jsFiles = files.filter(filename => filename.split(".").pop() === "js");
for (const filename of jsFiles) {
let command = require(`./commands/${filename}`);
if (!command) return console.error(`Command file '${filename}' doesn't export an object.`);
client.commands.set(command.name, command);
console.log(`Loaded command: ${command.name}`);
}
} catch (err) {
console.error(`Error loading command: '${err}'`);
}
console.log("Finished loading\n");
client.on("ready", () => {
console.log("Client ready!");
});
client.on("message", async message => {
if (message.author.bot) return;
if (!message.content.startsWith(prefix)) return;
let args = message.content.slice(prefix.length).trim().split(/ +/g);
//console.log(args);
let cmdName = args.shift().toLowerCase();
for (const command of client.commands.values()) {
console.log(command.name);
console.log(cmdName);
console.log(command === cmdName);
if (command.name !== cmdName /*&& !command.aliases.includes(cmdName)*/) return;
try {
await command.executor(message, args, client);
} catch (err) {
console.error(`Error executing command ${command.name}: '$```{err.message}'`);
}
}
});
client.login(TOKEN).catch(err => console.log(`Failed to log in: ${err}`));
and in each command module you have this bit:
module.exports = {
name: "command",
description: "description of command",
aliases: [],
executor: async function (message, args, client) {
(I have not done aliases for this yet, so alias lines are either empty or remmed out.)
You've incorrectly referenced your variable in the template literal which meant lots of your code was ignored, this likely is the entirety of the problem, it should look like this:
console.error(`Error executing command ${command.name}: ${err.message}`);
For guidance regarding template literals use https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals. If you wanted to use the ``` but have them ignored use this code:
console.error(`Error executing command ${command.name}: \`\`\` ${err.message} \`\`\` `);
In addition on your execute function you don't have closing braces so that should be:
module.exports = {
name: "command",
description: "description of command",
aliases: [],
executor: async function (message, args, client) {
// code to be executed
}
I'm writing a NodeJS application that can do some queueing in Discord. My main includes an array called queuedPlayers and is defined in the following code:
// Define our required packages and our bot configuration
const fs = require('fs');
const config = require('./config.json');
const Discord = require('discord.js');
// Define our constant variables
const bot = new Discord.Client();
const token = config.Discord.Token;
const prefix = config.Discord.Prefix;
let queuedPlayers = [];
// This allows for us to do dynamic command creation
bot.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
bot.commands.set(command.name, command)
}
// Event Handler for when the Bot is ready and sees a message
bot.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(' ');
const command = args.shift().toLowerCase();
if (!bot.commands.has(command)) return;
try {
bot.commands.get(command).execute(message, args);
} catch (error) {
console.error(error);
message.reply('There was an error trying to execute that command!');
}
});
// Start Bot Activities
bot.login(token);
I then create a command in a seperate JS file and I am trying to access the Queued Players array so that way I can add to them:
module.exports = {
name: "add",
description: "Adds a villager to the queue.",
execute(message, args, queuedPlayers) {
if (!args.length) {
return message.channel.send('No villager specified!');
}
queuedPlayers.push(args[0]);
},
};
However, it keeps telling me that it is undefined and can't read the attributes of the variable. So I'm assuming it isn't passing the array over properly. Do I have to use an exports in order to able to access it between different Javascript files? Or would it be best just to use a SQLite local instance to create and manipulate the queue as needed?
It's undefined because you aren't passing the array
Change
bot.commands.get(command).execute(message, args);
to
bot.commands.get(command).execute(message, args, queuedPlayers);
