# Telegram bot does not work 

## Bot is used on 2 devices

During startup/restart, the instance can run in two copies for about a second, which can cause such an error.
The error looks like this: 
```text
aiogram.utils.exceptions.TerminatedByOtherGetUpdates: Terminated by other getupdates request; make sure that only one bot instance is running
```
 
Try setting a delay of 2-5 seconds on object creation, this should help.

### Example for a bot in Python using telebot

Before

```python
bot = telebot.TeleBot(token) # or similar line
```

Register

```python
import time
time.sleep(5)
```

## Incorrect name of "telebot" in requirements.txt

The telebot in `requirements.txt` should be called `pyTelegramBotAPI`, not `telebot`. 

After replacing telebot with pyTelegramBotAPI, you need to freeze the project using the corresponding button on the tab 
"Settings". And only after that rebuild the application. 

Freezing is necessary to ensure that the cache is cleared, in which the old dependency may remain!

## No logs
If the application status is "Successfully launched" and the project uses the Python language, then to display the output of the `print` command 
You need to set the environment variable `PYTHONUNBUFFERED` to 1.
