I'm making a discord bot, and I'm trying to make use of the createChannel function shown here in the documentation. For some reason, I am getting the following error:

TypeError: bot.createChannel is not a function.

My code is within a function which I pass a message to, and I have been able to create roles and add users to roles within the same function. It's just the createChannel function that's not working. Below is the relevant portions of the code.

const bot = new Discord.Client();



function makeChannel(message){

    var server = message.guild;

    var name = message.author.username;



    server.createRole(data);

    var newrole = server.roles.find(name, name);

    message.author.addrole(newrole);



    /* The above 3 lines all work perfectly */





    bot.createChannel(server,name);

}

I have also tried bot.addChannel, and bot.ChannelCreate, since ChannelCreate.js is the name of the file which contains the code for this command. Also, I have attempted specifying channel type and assigning a callback function as well, but the main issue is the TypeError saying that this isn't a function at all. Any idea what I'm doing wrong?

Additionally, I plan to use ServerChannel.update() at some point in the future, so any advice on getting that to work once the previous problem is resolved would be greatly appreciated.
