Context

Bot uses webhooks, see above the method POST /process.
On every received message bot trying to get information about sender chat with method chat = await app.bot.get_chat(chat_id) and save it in save_telegram_chat function. Somebody deleted my bot from supergroup and after that calling method bot.get_chat(chat_id) raises ApiTelegramException. The strange thing is: ApiTelegramException produces 500 Internal Server Error and then telegram didn't receive 200 status and repeat sending the same message (with 'message_id': 10) again and again to bot. Also bot has ExceptionHandler and in this case exception handler doesn't work:

class BotExceptionHandler(ExceptionHandler):
    def __init__(self, app: Application):
        self.app = app

    async def handle(self, exception: Exception):
        error_str = repr(exception)
        logger.error(error_str)
        logger.error("Exception traceback:\n%s", traceback.format_exc())
        message = f'Bot exception occurred:\n{error_str}'
        await self.app.notifier.notify(message)
        return True

bot = AsyncTeleBot(
    token=settings.telegram.bot_token.get_secret_value(),
    exception_handler=BotExceptionHandler(app),
)

Error was fixed with adding try-except in save_telegram_chat function:

from telebot.asyncio_helper import ApiTelegramException

try:
    chat = await app.bot.get_chat(chat_id)
except ApiTelegramException as err:
    logger.warning(
        'Unable to get chat info for chat_id=%s when saving telegram chat',
        chat_id,
    )
    logger.error('Exception: %s', err)
    return None

But this fix seems as not a proper way, because the error looks like a bug somewhere in pyTelegramBotAPI.

Logs after fixing with try-except:

The strange thing is: ApiTelegramException produces 500 Internal Server Error and then telegram didn't receive 200 status and repeat sending the same message

Nothing wrong / strange. Your code failed to process request and did not send confirmation - thus Telegram retries. Handle errors in code (like you did) and everything will be fine.

[Badiboy]

Also bot has ExceptionHandler and in this case exception handler doesn't work

ExceptionHandler handles updates processing to handle exceptions when code is called not by you. For outgoing requests you did them yourself and you can easily handle exceptions.

No, not my code. I use telebot method get_chat, exception raises in telebot code. And then server response down with 500 status.

You should go deeper in my answers.
