I'm currently working on a discord bot that makes use of 'discord.js', 'discord.js-commando' and 'snekfetch'. I'm trying to create a function in which if a guild member were to type "!meme", the discord bot will grab a random post from r/dankmemes and send it to the respective channel using richEmbed. however, upon testing the function the following error messages appear:
TypeError: Cannot read property 'nsfw' of undefined
TypeError: Cannot read property 'send' of undefined
I've been trying to resolve the issue for 4 days and i'm utterly clueless as to what is causing this issue. According to the discord.js documentation this should work absolutely fine. I've attached the command module below:
const Commando = require('discord.js-commando');
const Discord = require('discord.js');
const snekfetch = require('snekfetch');
class MemesRssCommand extends Commando.Command
{
constructor(client)
{
super(client,{
name: 'meme',
group: 'simple',
memberName: 'meme',
description: 'Takes a random meme from r/dankmemes'
});
}
async run(client, message, args) {
try {
const { body } = await snekfetch
.get('https://www.reddit.com/r/dankmemes.json?sort=top&t=week')
.query({ limit: 800 });
const allowed = message.channel.nsfw ? body.data.children : body.data.children.filter(post => !post.data.over_18);
if (!allowed.length) return message.channel.send('Our farmers were unable to locate any ripe memes! Try again later (You shouldnt see this message. If you are reading this, then reddit is probably offline. If reddit is online and you still get this message, contact #𝕏𝕪𝕝𝕠𝕟𝕠𝕝𝕪#1612');
const randomnumber = Math.floor(Math.random() * allowed.length)
const embed = new Discord.RichEmbed()
.setColor(0x00A2E8)
.setTitle(allowed[randomnumber].data.title)
.setDescription("Posted by: " + allowed[randomnumber].data.author)
.setImage(allowed[randomnumber].data.url)
.addField("Other info:", "Up votes: " + allowed[randomnumber].data.ups + " / Comments: " + allowed[randomnumber].data.num_comments)
.setFooter("Posted by: " + allowed[randomnumber].data.author + " | Memes provided by https://www.reddit.com/r/dankmemes")
message.channel.send(embed)
} catch (err) {
return console.log(err);
}
}
}
module.exports = MemesRssCommand
According to the example in documentation the callback for run is run(message, args) but you are defining it as run(client, message, args), thus the message.channel is undefined since you are trying to access it on the wrong object.
async run(message, args) {
const member = args.member;
const channel = message.channel
// ....
}

why register slash commands with options doesn't work (discord.js)

Closed 2 months ago.
At the time I am trying to learn how to make a discord bot and I got an error I dont know waht it means or how to fix it. I made a command for welcome messages with a youtube tutorial and now it stopped working.
Error:

const roleId = options.getRole("welcome-role");
if(!interaction.guild.members.me.permissions.has(PermissionFlagsBits.SendMessages)) {
interaction.reply({content: "I don't have permissions for this.", ephemeral: true});
}
welcomeSchema.findOne({Guild: interaction.guild.id}, async (err, data) => {
if(!data) {
const newWelcome = await welcomeSchema.create({

}
}
I tried a few things like changing the construction of the bot or change some thing like the command options.
Thanks in advance!
Your Channel argument is invalid, since all names need to be lowercase only. Change it to channel, for example, and it will work.
I wrote a new command when my bot ran on my pc and not a server.
While the bot ran on my pc the command worked very well, but after I put my bot into a server
the command stopped working and I always get an error message:
DiscordAPIError: Cannot send an empty message

constructor() {
super('help', 'moderation', []);
}
async run(client, message, args) {
const y = moment().format('YYYY-MM-DD HH:mm:ss')

A couple of things. Are you sure that this reconlx package is compatible with your discord.js version? It's always a good idea to post your discord.js version when you have a problem with libraries.
If you're using reconlx v1, you can see in their old documentation that in ReactionPages the second parameter takes an array of embeds. If you check the source code, you can see that it tries to send the first item of pages as an embed, like this: message.channel.send({ embeds: [pages[0]] }).
It means that with your code embeds is an array where the first item is an object that has an embed key with the sayEmbed1 embed, while discord.js accepts an array of MessageEmbeds.
I would try to pass down an array of embeds like this:
const pages = [
sayEmbed1,
sayEmbed2,
sayEmbed3,
sayEmbed4,
sayEmbed5,
sayEmbed6,
];
PS: ki írni is incorrect. When the verb particle precedes the verb, they are written as one word. So, it should be kiírni. :)
In the code provided, there appears to be no code that references "{embeds:[embed]}".
However, assuming the error is coming from this line:
message.channel.send('Nem tudom ki írni az üzenetet');
Referring to the official documentation, you can provide an object.
For example:
message.channel.send({ content: 'Nem tudom ki írni az üzenetet' });
first time poster looking for some help, struggling to get this to work. I'm wanting to create a command which followed by a channel mention and Raw JSON will then post an embed in the mention channel. The code itself throws up no errors, until the point I initiate the command, where I get "TypeError: Cannot read property 'mentions' of undefined". Any ideas where I've gone wrong?
const DiscordJS = require('discord.js')
const WOKCommands = require('wokcommands')
require('dotenv').config();
module.exports = {
name: "embedjson",
category: "info",
description: "post embed from json data",
minArgs: 2,
expectedArgs: '<Channel mention> <JSON>',
run: async ({client, message, args, level }) => {
// get the target channel
const targetChannel = message.mentions.channels.first()
if (!targetChannel) {
message.reply('Please specify a channel to send the embed in')
return
}
// removes the channel mention
args.shift()
try {
// get the JSON data
const json = JSON.parse(args.join(' '))
const { text = '' } = json
// send the embed
targetChannel.send(text, {
embed: json,
})
} catch (error) {
message.reply(`Invalid JSON ${error.message}`)
}
},
}
I'm getting a "Cannot access 'person' before initialization" Error. I don't have const person anywhere else except this file. I'm new to js so I'm not sure what I'm doing wrong.
Edit: I fix that error but now I'm getting a different error message. "UnhandledPromiseRejectionWarning: ReferenceError: getMember is not defined".
const Discord = require('discord.js');
module.exports.run = async (bot, message, args) => {
const love = Math.random() * 100;
const loveIndex = Math.floor(love / 10);
const loveLevel = "💖".repeat(loveIndex) + "💔".repeat(10 - loveIndex);
const embed = new Discord.MessageEmbed()
.setColor("#ffb6c1")
.addField(`☁ **${person.displayName}** loves **${message.member.displayName}** this much:`,
`💟 ${Math.floor(love)}%\n\n${loveLevel}`);
let person = getMember(message, args[0]);
if (!person || message.author.id === person.id) {
person = message.guild.members
.filter(m => m.id !== message.author.id)
.random();
message.channel.send(embed);
}}
module.exports.config = {
name: "love",
description: "Calculates the love affinity you have for another person.",
usage: "[mention | id | username]",
accessableby: "Members",
aliases: ["affinity"]
}
On this line:
.addField(`☁ **${person.displayName}** loves **${message.member.displayName}** this much:`,
person is not defined.
Try moving the block where you initialize person up above the const embed = ... statement.
That error is usually caused by trying the make a reference to a class before the code for the class itself is initialized. Try declaring person after class definition.
I'm working on a command where when you do the command, d!woa the following happens
A webhook gets created with a certain name, Then a role gets created with the channel name, after that the bot watches if there's a webhook with that certain name for the channel, and just sees if anyone sends a message in that channel. If it does, then the bot will add that role with the certain name.
The problem is that there's this error : TypeError: Cannot read property 'guild' of undefined
The error will most likely appear at the end of the code provided.
I've tried rearranging the code, defining guild, and defining message. It does not seem to work even after trying all of this. I only want it to rely off of the ID instead of Name to be accurate for this command.

I expect a command without the TypeError, and the command able to create a role and a webhook (for a marker), and the role is automatically set so that the user that has the role won't be able to speak in the channel, and whoever speaks in the channel will get the role.
The actual output is a TypeError: Cannot read property 'guild' of undefined but a role and webhook are created.
You have var sbwrID = member.guild...
You did not define member. Use message.member.guild...
You can setup a linter ( https://discordjs.guide/preparations/setting-up-a-linter.html ) to find these problems automatically.
