Pass your handler class with exception_handler parameter of TeleBot constructor. It will be called if any exception occurs.

[Zapzatron]

import logging

logger = telebot.logger
telebot.logger.setLevel(logging.ERROR) # Outputs debug messages to console.

class ExceptionHandler(telebot.ExceptionHandler):
def handle(self, exception):
print(exception)
# logger.error(exception)

bot = telebot.TeleBot(read_file(f'{data_dir}/tokens.ini')[0][10:], exception_handler=ExceptionHandler())
I make this for catching, but why this don`t catch errors which highlighted in red

return True

in handler if you done handling.

Thx, now this catching excellent

[Zapzatron]

Why wouldn't it work?
import logging

logger = telebot.logger
telebot.logger.setLevel(logging.ERROR) # Outputs debug messages to console.

class ExceptionHandler(telebot.ExceptionHandler):
def handle(self, exception):
print(exception)
print(exception[-97:])
print(exception[:-97])
if exception[-97:] == "Conflict: terminated by other getUpdates request; make sure that only one bot instance is running":
print("ERROR: ", exception)
return True
# logger.error(exception)

bot = telebot.TeleBot(read_file(f'{data_dir}/tokens.ini')[0][10:], exception_handler=ExceptionHandler())

[Zapzatron]

I don`t know, how this works but this works without red.
