Way To Check If A Channel Exists

module.exports.run = async (bot, message, args) => { let ticketreason = args[1]; let ticketname = 'ticket' + ticketreason; message.guild.createChannel('tickets',

Solution 1:

You can use <Guild>.channels, which returns a collection of GuildChannels, from this collection you can use <Colection>.exists() to check if the channel already exists in the guild.

So something like this:

if (message.guild.channels.exists('name', ticketname)) { //checks if there in an item in the channels collection that corresponds with the supplied parameters, returns a boolean
    message.reply(`The ${ticketname} channel already exists in this guild.`).catch(console.error);
    return; //prevents the rest of the code from being executed
}

// Code that creates the channel {ticketname}...

Solution 2:

I do it in the following way, and I go through each of the channels.

let nameOfChannel = "lista-" + message.author.username.toLowerCase();

        // Check if channel exist
        if ((message.guild.channels.cache.find(c => c.name.toLowerCase() === nameOfChannel))) {

---- code continue here----

Solution 3:

You can do this by checking for the id. While this might not resolve this particular issue, it might help others with a similar issue.:

var chan_id;

if(message.guild.channels.cache.get(chan_id) === undefined)  { 
    //checks if the channel doesn't exist
    //put the action to take here
} 
//continue your code here
