Bot not returning a message. How do I fix this?

require('dotenv').config();
const { Client, IntentsBitField } = require('discord.js');
const { Configuration, OpenAIApi } = 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 configuration = new Configuration({
    apiKey: process.env.API
});

const openai = new OpenAIApi(configuration);

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.reverse();

    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;

        conversationLog.push({
            role: 'user',
            content: message.content,
        });
    });

    conversationLog.push({
        role: 'user',
        content: msg.content
    });



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

    msg.reply(res.data.choices[0].message);
});

client.login(process.env.TOKEN);
