I cannot run the bot on Heroku

[OmegaM1]

Hi, I have setup my bot on Heroku by using heroku-node-telegram-bot code examples but I am getting below error

 heroku-node-telegram-bot@1.0.3 start
 node index.js

/app/bot.js:7
  bot = new Bot(token);
        ^

TypeError: TelegramBot is not a constructor

    at Module._compile (node:internal/modules/cjs/loader:1105:14)
    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1159:10)

Process exited

Is there a way to fix it?

Add const before "bot"

// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, {polling: true});

@Drakoniwe Thank you, the pervious problem has been solved But I am receiving a new error which the logs telling that my bot token is not defined

node-telegram-bot-api deprecated Automatic enabling of cancellation of promises is deprecated.
In the future, you will have to enable it yourself.

I have already defined my Heroku URL with the bot token so what's the problem

[OmegaM1]

I found the problem which it was my code I edited "bot.token" to "token" (String variable) and it worked.
