I was trying to send an image when a member joins to my server with @napi-rs/canvas
in discord.js 14.
When the bot tries to send the message this error appears.
I was trying to make it with discordjs.guide
Cannot read properties of undefined (reading 'cache')
This is the code of my event:
const { Events, AttachmentBuilder} = require('discord.js');
const Canvas = require('@napi-rs/canvas');
module.exports = {
name: Events.GuildMemberAdd,
async execute(client) {
const canvas = Canvas.createCanvas(1024, 500);
const context = canvas.getContext('2d');
const background = await Canvas.loadImage('./resources/canvas/images/welcome.png');
context.drawImage(background, 0, 0, canvas.width, canvas.height);
const attachment = new AttachmentBuilder(await canvas.encode('png'), { name: 'profile-image.png' });
console.log ('sending message')
const channel = client.channels.cache.get('1099656104100769924');
channel.send(({ files: [attachment] }));
},
};
And this is my index.js
file
const { Client, Collection, Events, GatewayIntentBits } = require('discord.js');
const fs = require('node:fs');
const path = require('node:path');
const { token, prefix } = require('./config.json');
const { channel } = require('node:diagnostics_channel');
const client = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.MessageContent, GatewayIntentBits.GuildMessages, GatewayIntentBits.GuildMembers]});
client.commands = new Collection();
const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath).filter(file => file.endsWith('.js'));
for (const folder of commandFolders) {
const commandsPath = path.join(foldersPath, folder);
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)
if ('data' in command && 'execute' in command) {
client.commands.set(command.data.name, command);
} else {
console.log(`[WARNING] The command on ${filePath} dont have "data" or "execute" property.`);
}
}
}
const eventsPath = path.join(__dirname, 'events');
const eventFiles = fs.readdirSync(eventsPath).filter(file => file.endsWith('.js'));
for (const file of eventFiles) {
const filePath = path.join(eventsPath, file);
const event = require(filePath);
if (event.once) {
client.once(event.name, (...args) => event.execute(...args));
} else {
client.on(event.name, (...args) => event.execute(...args));
}
}
client.login(token);
I tried many solutions and nothing worked I am using the latest version of discord.js v14.
>Solution :
The GuildMemberAdd
event takes a single parameter, the member that has joined a guild. That means client
in async execute(client)
is not a client, but a GuildMember
.
You can change it to:
async execute(member) {
// ...
}
As GuildMember
s have a client
property, you can simply use:
const channel = member.client.channels.cache.get('1099656104100769924');
