TypeError: openai.createChatCompletion is not a function

Getting this error whenever I try to run the code from the video.

require('dotenv').config(); const { Client, IntentsBitField } = require('discord.js'); OpenAI = require('openai');

const client = new Client({ intents: [ IntentsBitField.Flags.Guilds, IntentsBitField.Flags.GuildMessages, IntentsBitField.Flags.MessageContent, ] })

client.on('ready', () => { console.log('ChatGPT is online'); })

const openai = new OpenAI({ apiKey: process.env.API });

client.on('messageCreate', async (msg) => { if(msg.author.bot) return; if(msg.channel.id !== process.env.CHANNEL) return; if(msg.content.startsWith('!')) return;

let conversationLog = [{
    role: 'system',
    content: 'You are a friendly chatbot'

await msg.channel.sendTyping();

let previousMessages = await msg.channel.messages.fetch({ limit: 15 });

previousMessages.forEach((message) => {
    if(msg.content.startsWith('!')) return;
    if(message.author.id !== client.user.id && msg.author.bot) return;
    if(message.author.id !== msg.author.id) return;

        role: 'user',
        content: message.content,

const res = await openai.createChatCompletion({
    model: 'gpt-3.5-turbo',
    messages: conversationLog,

Hiya Matthew Bradshaw! 👋 Our apologies for the issues that you are running into!

Like many aspects of technology, software packages are often updated frequently. Consequently, a method or feature that functions properly in one version may become obsolete or altered in subsequent releases. This appears to be the scenario with the OpenAI Node.js library, where certain functionalities have seemingly been deprecated or changed following the v4 update. Luckily, there is a handy v3 to v4 migration guide if you want to follow along with that.

Another option would be to run npm uninstall openai in the terminal, then run npm i openai@3.3.0 to specify the final version of v3, which will match the code in the video.
