我在node.js中创建了一个电报机器人。在localhost上运行良好。但是当我试图在渲染中部署它时，它显示构建成功，并且在启动服务时我得到一个错误：ETELEGRAM：409由其他getUpdates请求终止;确保只有一个bot示例正在运行”}。我没有运行任何其他示例。
我想在渲染中部署我的电报机器人。下面是我的代码：

import TelegramBot from "node-telegram-bot-api";
    import { Configuration, OpenAIApi } from "openai";
    import { config } from "dotenv";

    config()

    const TOKEN = process.env.TELEGRAM_TOKEN

    const bot = new TelegramBot(TOKEN, {polling:true} )
    let firstMsg = true;

    bot.on('message', (message)=>{
        if (firstMsg) {
            bot.sendMessage(message.chat.id, `Hello ${message.chat.first_name}, use "/prompt" followed by your query`)
            firstMsg = false
        }
    })

    bot.onText(/\/prompt (.+)/, (msg, match) => {
        const chatId = msg.chat.id
        const messageText = match[1]

        

        openai.createChatCompletion({
            model:"gpt-3.5-turbo",
            messages:[{role:"user", content:messageText}]
        }).then(res=>{
            const result = (res.data.choices[0].message.content) 
            bot.sendMessage(chatId, result);
        })
        

      });
      
    const openai = new OpenAIApi(new Configuration({
        apiKey:process.env.CHATGPT_API
    }))
