Discord Bot can't find channel by name or id

Question

I'm trying to make a discord bot with node.js I want to post message only in specific channel I tried to do that to save a channel in a variable but that doesn't work :

const Discord = require('discord.js');
const fs = require("fs");

var bot = new Discord.Client();
var myToken = 'NDQ2OTQ1...................................................';
//client.msg = require ("./char.json");

var prefix = ("/");

//let preset = JSON.parse(fs.readFileSync('preset.json', 'utf8')); // This calls the JSON file.


var offTopic = bot.channels.find("id","448400100591403024"); //.get("448392061415325697");
console.log(offTopic);

Whenever i run my bot it returns 'null' with find and 'undefined' with get. I search for help on internet and even if i follow this post my code doesn't work : Discord Bot Can't Get Channel by Name I also tried to find my channel by name but i got 'undefined' too :/

Answer 1

It seems like the new version of the library uses .fetch instead of .get and it returns a promise:

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  client.channels.fetch('448400100591403024')
    .then(channel => console.log(channel.name));
});

Answer 2

The way you retrieve information from client changed in discordjs v12, that applies if the information was cached tho.

var offTopic = bot.channels.cache.get('448400100591403024'); //.get('448392061415325697');
console.log(offTopic);

If the information isn't cached, you will need to use the fetch method that Taylan suggested. This method uses Discord API to get the Discord object by an ID.

client.channels.fetch('448400100591403024')
  .then(channel => console.log(channel.name));

You can read more about changes brought with discordjs v12 here

Answer 3

    bot.on('ready', (message) => {
        var offTopic = client.channels.cache.get("448400100591403024")
        console.log(offTopic)
    })

Answer 4

You can do it either via .then promise call or via async await as explained here: .

Code will be like this (change the variable client to your bot if needed):

let channel = await client.channels.fetch('channel-id-here')

// or you can use:

client.channels.fetch('channel-id-here').then( () => {
  // do something here
})

I hope it helps both sort of scenarios.
