My telegram bot is crashing on Heroku. Who knows how to fix it?

Question

Node.js

Here are the logs:

2020-05-01T17:03:06.216123+00:00 heroku[web.1]: State changed from starting to crashed

Bot.js (the rest is bot logic):

const Telegram = require('node-telegram-bot-api');
const bot = new Telegram("Токен", {
polling: true
})

const API_PORT = process.env.PORT || 3000

console.log("Bot запущен")

Procfile:
web: node bot.js
package.json:

{
"name": "cs_guides",
"version": "1.0.0",
"description": "",
"main": "bot.js",
"scripts": {
"start": "node bot.js",
"test": "echo "Error: no test specified" && exit 1"
},
"engines": {
"node": "12.16.3"
},

"author": "",
"license": "ISC",
"dependencies": {
"node-telegram-bot-api": "^0.40.0"
},
"devDependencies": {
"nodemon": "^2.0.3"
}
}

The bot works on LAN without errors and crashes. Compiled on my VS code.

First, after uploading the commit, the bot works fine for ~5 minutes. After it crashes and from 1 minute to 5 minutes it does not work and starts. Who knows what can be done to solve the problem or at least reduce the time the bot is not working.

Answer 1

Heroku is famous for its unstable work with telegram bots. You are not the only one experiencing such difficulties. Many bots get stuck or fall asleep while working.
Possible solutions:
1) Restart the bot on exit. I can not give the code - I write it myself in another language.
2) Use a different hosting for the bot. I use paid. There are no problems with sticking the bot.
