Discord ChatGPT Bot

I’ve made bot for my discord server and tried to make it use ChatGPT. After sending message on chat it only types error and in terminal it says error no.429

const { Client, GatewayIntentBits } = require('discord.js');
const axios = require('axios');

const client = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent] });
const OPENAI_API_KEY = 'My code';
const DISCORD_BOT_TOKEN = 'My code';

const MIN_DELAY_BETWEEN_REQUESTS = 10000; // adjust this based on your rate limits

let lastRequestTime = 0;

const waitForRateLimit = () => {
    const now = Date.now();
    const delay = Math.max(0, MIN_DELAY_BETWEEN_REQUESTS - (now - lastRequestTime));
    return new Promise(resolve => setTimeout(resolve, delay));
};

client.on('messageCreate', async (message) => {
    if (message.author.bot) return;

    await waitForRateLimit(); // wait for appropriate delay
    lastRequestTime = Date.now();

    try {
        const response = await axios.post('https://api.openai.com/v1/chat/completions', {
            model: 'gpt-3.5-turbo',
            messages: [{ role: 'user', content: message.content }]
        }, {
            headers: {
                'Authorization': `Bearer ${OPENAI_API_KEY}`,
                'Content-Type': 'application/json'
            }
        });

        const botReply = response.data.choices[0].message.content;
        message.reply(botReply);
    } catch (error) {
        if (error.response?.status === 429) {
            message.reply('I am receiving too many requests, please try again later.');
        } else {
            message.reply('An error occurred. Please try again.');
        }
        console.error('Error with OpenAI API:', error);
    }
});

client.login(DISCORD_BOT_TOKEN);

I tried to add delay for 3, 5 and even 10 seconds
