node.js - Cannot read property 'get' of undefined discord.js

Question

I've been trying to send message to a particular text channel in a server using the channelId but I end up getting the error:

TypeError: Cannot read property 'get' of undefined
    at Object.<anonymous>

when using

  const channel = bot.channels.cache.get('711580200315650078');

here is my entire code:

require('dotenv').config();
const Discord = require('discord.js');
const bot = new Discord.Client();
const TOKEN = process.env.TOKEN;

bot.login(TOKEN);

bot.on('ready', () => {
  console.info(`Logged in as ${bot.user.tag}!`);
  const channel = bot.channels.cache.get('711580200315650078');
  channel.send('hello');
  
});

Answer 1

You can try:

require('dotenv').config();
const Discord = require('discord.js');
const bot = new Discord.Client();
const TOKEN = process.env.TOKEN;

bot.login(TOKEN);

bot.on('ready', () => {
  console.info(`Logged in as ${bot.user.tag}!`);
  const channel = bot.channels.get('711580200315650078');
  channel.send('hello');
  
});

This is probably because you're using Discord.js v11. You should migrate to v12, using npm install discord.js. You will then be able to use:

const channel = bot.channels.cache.get('711580200315650078');
