Discord API error : cannot send an empty message - javascript

I was following a YouTube tutorial on how to program a discord bot, and I came across the infamous error "cannot send an empty message" while trying to send an embed. Here is my code :
main.js :
const Discord = require('discord.js');
const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });
const prefix = '!';
const fs = require('fs');
client.commands = new Discord.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.name, command);
}
client.once('ready', () => {
console.log('Picobot is ready for use!');
});
client.on('message', message =>{
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if (command === 'ping') {
client.commands.get('ping').execute(message, args);
} else if(command === 'pong') {
client.commands.get('pong').execute(message, args);
} else if(command === 'permissions') {
client.commands.get('permissions').execute(message, args);
}
if (command === 'embed') {
client.commands.get('command').execute(message, args, Discord);
}
});
embed.js :
module.exports = {
name: 'embed',
description: 'Embeds',
execute(message, args, Discord) {
const newEmbed = new Discord.MessageEmbed()
.setColor('#304281')
.setTitle('Rules')
.setURL('https://www.youtube.com/watch?v=dQw4w9WgXcQ')
.setDescription('This is a test embed')
.addFields(
{name: 'Rule 1', value: 'Placeholder 1'},
{name: 'Rule 2', value: 'Placeholder 2'},
{name: 'Rule 3', value: 'Placeholder 3'},
)
.setImage('https://images.radio-canada.ca/q_auto,w_960/v1/ici-info/16x9/rick-astley-videoclip-never-gonna-give-you-up.png');
message.channel.send({ newEmbed:newEmbed });
}
}
I have seen a number of other people having this error, the only solutions I've found and tried so far were to change message.channel.send({ newEmbed:newEmbed }) to message.channel.send(newEmbed), but the same error still pops up. I haven't seen any answered problems about this error in 2021, so I figured I'd shoot my shot here, thanks in advance.

Transitioning from v12 to v13 we have encountered another weary change that makes no sense to some users
// message.channel.send(newEmbed) does not work anymore
message.channel.send({
embeds: [newEmbed]
});
// The above is the way to go!
Another change: the message event listener:
client.on("message", () => {})
is depreciated and has been changed to messageCreate.

In v13 sending embeds is structured as such:
message.channel.send({ embeds: [newEmbed] });

TypeError: Cannot read properties of undefined (reading 'execute') command handler

const discord = require('discord.js')
const client = new discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })
const prefix = '&';
const fs = require('fs');
client.commands = new discord.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.name, command);
}
client.on('ready', () => {
console.log("================");
console.log("|Bot is ready|");
console.log("================");
});
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'ip'){
client.commands.get('ip').execute(message, args);
} else if (command == 'creator'){
client.commands.get('creator').execute(message, args);
} else if (command == 'rulespost'){
client.commands.get('rulespost').execute(message, args, discord);
} else if(command == 'test'){
client.commands.get('test').execute(message, args);
}
})
And with this I get an error with 'rulespost' saying TypeError: Cannot read properties of undefined (reading 'execute')
and within rulespost.js is
module.exports = {
name: 'RulesPost',
description: "Posts the rules of the server",
execute(message, args, discord) {
const newEmbed = Discord.MessageEmbed()
.setColor('#000000')
.setTitle('Official Rules for ALL Platforms')
.setDescription('...')
.addFields(
{value: 'TEXT'}
)
message.channel.send(newEmbed)
}
}
And when using the &rulespost command the bot dies and nothing else happens.
all other commands work fine with no problems but trying to use the embed command it kills the bot completely.
Note this is WRONG, however it can not be taken down as it is marked for some reason.
the syntax for the execute function is incorrect. The interpreter thinks that you are calling a function and then passing further items to the object. this can be fixed by adding the function keyword or by assigning execute to an anonymous function like so:
module.exports = {
name: 'RulesPost',
description: "Posts the rules of the server",
// Execute is the key for the anon. function
execute: function(message, args, discord) {
const newEmbed = Discord.MessageEmbed()
.setColor('#000000')
.setTitle('Official Rules for ALL Platforms')
.setDescription('...')
.addFields(
{value: 'TEXT'}
)
message.channel.send(newEmbed)
}
}
This creates the execute function that you are exporting.

Discord Bot error comes up trying to add a role

Trying to make a "mute command" comes up with TypeError: Cannot read property 'add' of undefined If you could help me Thanks :)
module.exports = {
name: 'mute',
description: 'f',
execute(message, args) {
const taggedUser = message.mentions.users.first();
const mutedRole = "800612654234337281"
if (!message.mentions.users.size) {
return message.reply(`Oh, thats unexpected you haven't tagged anyone.`);
}
message.channel.send(`${taggedUser} has been muted`);
taggedUser.roles.add(mutedRole);
},
};
Here is the "main file" if there is an issue with this
const fs = require('fs');
const Discord = require('discord.js');
const client = new Discord.Client();
const { prefix, token } = require('./config.json');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.once('ready', () => {
console.log('Online');
});
client.on('message', message => {
const args = message.content.slice(prefix.length).trim().split(' ');
const command = args.shift().toLowerCase();
if (!client.commands.has(command)) return;
try {
client.commands.get(command).execute(message, args);
} catch (error) {
console.error(error);
message.reply('there was an error trying to execute that command!');
}
});
client.login(token);
This will not work because discord user and guild member both are completely different methods. You cannot add roles to discord user in any guild (unless your bot is in the said guild), you can only add roles to guild member.
replace:
message.mentions.users.first()
with:
message.mentions.members.first()

Execute undefined while making embed

My code:
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'canyouhelp'){
client.commands.get('newmodreportsupport').execute(message, args, Discord)
}
});
--in commands folder--
module.exports ={
name: 'canyouhelp',
description: "Help around the server in general",
execute(message, args, Discord) {
const newEmbed = new Discord.MessageEmbed()
.setColor('#763782')
.setTitle('Help around the server!')
.setURL('https://discord.gg/qVvvGW4')
.setDescription('This should guide you around the server!')
.addFields(
{name: 'New to Discord 👨‍🏫', value: 'So your new to discord? Well thats no problem! Discord is a very easy platform to use. For a detailed explination on how to use it type "-newtothegame" in chat and I will get back to you'},
{name: 'Need to Talk to a Moderator 🙋‍♂️', value: 'You need to get in touch with a moderator, admin or helper well then just type "-getmethroughtoamod" and I will get back to you!'}
)
.setFooter('Make sure you type in the commands letter for letter or it will not work');
message.channel.send(newEmbed);
}
}
The javascript file in commands folder is called newmodreportsupport.js
Terminal: TypeError: Cannot read property 'execute' of undefined
I cant understand why this is happening can someone please explain and hopefully correct.
Thank you!
inside client.commands.get('newmodreportsupport').execute(message, args, Discord) you need to specify the name of the module which is 'canyouhelp' for you, not the file name. so it should be:
client.commands.get('canyouhelp').execute(message, args, Discord)
Also we can't see your whole code but I imagine you don't even have the bot.commands collection. You need to load your command modules into that like so:
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
So your code should look like this:
const Discord = require('discord.js');
const client = new Discord.Client();
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.on('ready', () => {
console.log('bot is ready!');
});
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'canyouhelp'){
client.commands.get('canyouhelp').execute(message, args, Discord)
}
});
bot.login(token);

Call for a command, multiply every times the embeded fields

Hello.
I coded a simple MessageEmbed function (with Discord.JS) and every time that I call it, the new embed that is sent in the channel has his field who adds up with the precedent
(e.g.: if the embed should have 2 fields, the next time that the command will be called it will have 2*2 the required fields. If you call it again, 3*2, 4*2, etc.).
When I restart the bot it reset. I tried to reset the embed value but it didn't affect the problem.
Could you help me please ?
Here is my JS command :
module.exports = {
name: 'drive',
execute(client, message, args, embed) {
message.channel.send(embed
.setColor('#0099ff')
.setTitle('abcdedfg')
.setDescription('abcdedfg \n\u200B')
.setThumbnail('abcdedfg')
.addFields(
{ name: 'abcdedfg :', value: 'link' },
{ name: 'abcdedfg :', value: 'link \n\u200B' },
)
.setFooter('abcdedfg'))
.catch(console.error);
}
}
And here is my main if needed :
const fs = require('fs');
const { Client, Collection, MessageEmbed } = require('discord.js');
const { TOKEN, PREFIX } = require('./config/config');
const client = new Client();
client.commands = new Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
const embed = new MessageEmbed();
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.on('message', message => {
if (!message.content.startsWith(PREFIX) || message.author.bot) return;
const args = message.content.slice(PREFIX.length).split(/ +/);
const command = args.shift().toLowerCase();
if (!client.commands.has(command)) return;
client.commands.get(command).execute(client, message, args, embed);
});
client.login(TOKEN);
I found the answer to block the fields from being added every times to the the fields array here on StackOverFlow.
So the code answer is addind a embed.fields = []; at the end :
module.exports = {
name: 'drive',
execute(client, message, args, embed) {
message.channel.send(embed
.setColor('#0099ff')
.setTitle('abcdedfg')
.setDescription('abcdedfg \n\u200B')
.setThumbnail('abcdedfg')
.addFields(
{ name: 'abcdedfg :', value: 'link' },
{ name: 'abcdedfg :', value: 'link \n\u200B' },
)
.setFooter('abcdedfg'))
.catch(console.error);
embed.fields = [];
}
}
Its quite simple. don't add fields. adding fields is what adds new fields so if you do not want them do not add them. else, clear the old ones before adding new ones.
My recommendation, use this;
module.exports = {
name: 'drive',
execute(client, message, args, embed) {
message.channel.send(embed
.setColor('#0099ff')
.setTitle('abcdedfg')
.setDescription('abcdedfg \n\u200B')
.setThumbnail('abcdedfg')
.setFooter('abcdedfg'))
.catch(console.error);
}
}
Try this and let's see.
As long as the first fields exist, you don't ever have to add.

module.export and getting user information

I'm trying to display client.user.avatarURL in a command file through module.export using:
...
icon_url: client.user.avatarURL;
...
but when I call the command through the bot I have this error in the console:
TypeError: Cannot read property 'avatarURL' undefined
I've tried getting the value of the client on a const and pass it true the command handler but didn't solve it as well. If you delete that line everything works fine, so I guess is just a wrong way to pass client informations.
main.js
const fs = require('fs');
const Discord = require('discord.js');
const { prefix, token } = require('./config.json');
const client = new Discord.Client();
client.commands = new Discord.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.name, command);
}
client.once('ready', () => {
console.log('Online!');
});
client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const commandName = args.shift().toLowerCase();
if (!client.commands.has(commandName)) return;
const command = client.commands.get(commandName);
if (command.args && !args.length) {
let reply = `You didn't provide enough arguments, ${message.author}!`;
if (command.usage) {
reply += `\nThe proper usage would be: \n\`${prefix}${command.name} ${command.usage}\``;
}
return message.channel.send(reply);
}
try {
command.execute(message, args, client);
}
catch (error) {
console.error(error);
message.reply('there was an error trying to execute that command!');
}
});
client.login(token);
and the command file:
module.exports = {
name: 'help',
description: 'Help file',
execute(message, client) {
message.channel.send({ embed: {
color: 0xf7da66,
author: {
name: 'Bot',
icon_url: client.user.avatarURL,
},
title: 'commands guide',
description: 'This is an discord bot.',
fields: [{
name: 'Command',
value: 'Type: example.',
},
],
timestamp: new Date(),
footer: {
icon_url: client.user.avatarURL,
text: '© Bot',
} } });
},
};
You are doing: command.execute(message, args, client); but then execute(message, client) { wich means that in your command file client is now actually the array args.
You need to do: execute(message, args, client) {
You need to use module.exports = (client, message, args) => { instead.
