Why does the bot crash after launch after about 1 minute?

Question

Node.js

Hello, I decided to play with bots in Telegram at my leisure.

I made a simple one from the lessons, everything works fine on the local, but when deployed to Heroku, it stops working after about a minute. Log:

2021-10-27T13:20:53.523824+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
2021-10-27T13:20:53.973649+00:00 heroku[web.1]: Stopping process with SIGKILL
2021-10-27T13:20:54.119848+00:00 heroku[web.1]: Process exited with status 137
2021-10-27T13:20:54.177180+00:00 heroku[web.1]: State changed from starting to crashed

I tried to add to Procfile:

web: node index.js -p $PORT

As a result, it launched with port 18119 but did not solve the problem.
I would be happy to get help from those in the know.

Bot code:

const TelegramApi = require('node-telegram-bot-api')

const token = 'ТОКЕН';

const bot = new TelegramApi(token, { polling: true })

bot.on('message', msg => {
    console.log(msg)
    const chatId = msg.chat.id;
    const text = msg.text;
    bot.sendMessage(chatId, 'Вы написали ' + text)

    if (text == '/start') {
        bot.sendMessage(chatId, "Hi, I'll text you when someone visits the site.")
    }
})

Let me summarize. The bot works correctly for the first, approximately, 60 seconds. Then an error in the log, and nothing.

Try
worker: node index.js -p $PORT

It also crashes in this mode, but it seems to restart itself
