I'm following a tutorial on discord.js, making a ticket bot. I have doubled checked and I am still getting the same error:

TypeError: channel.updateOverwrite is not a function

I've looked over all the StackOverflow questions that I could find, but none has worked for me. I have also explored a little deeper outside of stack, still no help. Here is my code:

module.exports = {
    name: 'ticket',
    description: 'Open a ticket!',

            { type: 'text' }
        );
        await channel.setParent('912495738947260446');

        // updates channel perms

        channel.updateOverwrite(message.guild.id, {
            SEND_MESSAGE: false,
            VIEW_CHANNEL: false
        });

        channel.updateOverwrite(message.author, {
            SEND_MESSAGE: true,
            VIEW_CHANNEL: true
        });

        const reactionMessage = await channel.send('Thanks for opening a ticket! A staff member will be with you shortly. While you are here, please tell us why you opened this ticket.');

        try {
            await reactionMessage.react("
