How turn on Exception traceback in AsyncTeleBot

[Pankovea]

If I use Telebot, then when an error occurs, I get an expanded Exception traceback 

[2025.01.08 20:51:51] Infinity polling exception: 'Message' object has no attribute 'fom_us'
[2025.01.08 20:51:51] Exception traceback:
Traceback (most recent call last):
  ...
  File "/config/workspace/src_dev/classes/log.py", line 99, in alltext
    print(m.fom_us)
          ^^^^^^^^
AttributeError: 'Message' object has no attribute 'fom_us'

But when I use AsyncTeleBot, Exception traceback is not output. 

[2025.01.08 20:49:53] Starting your bot with username: [@youre_bot]
[2025.01.08 20:50:34] Received 1 new updates
[2025.01.08 20:50:34] 'Message' object has no attribute 'fom_us'

How do I enable this information?

[Pankovea]

I was able to enable Exception traceback with
telebot.logger.setLevel(logging.DEBUG)
but in this case there is a lot of unnecessary information

TeleBot: "Processing updates....
TeleBot: "Request:...

I'm moving in the direction of filtering.
There is a lack of information and examples about this in the Official documentation

[Pankovea]

My solution is. It seems to work as it should.

class TracebackFilter(logging.Filter): 
    def filter(self, record):
        return record.levelno > logging.DEBUG or 'Exception traceback:' in record.msg

telebot.logger.setLevel(logging.DEBUG)
telebot.logger.addFilter(TracebackFilter())

Is that what i should have done?

[Pankovea]

Now I get, for example, 

  File "/config/workspace/src_dev/classes/users.py", line 362, in update
    if str(cid) not in self.chats.keys():
                       ^^^^^^^^^^^^^^^
AttributeError: 'str' object has no attribute 'keys' 

Is there any way to get the values of local variables? Or at least would be the value of the specific variable that caused the error?

[Pankovea]

My solution:
And Maybe add this feature to the package? This way it will be much easier to remove the code.
I made a decorator for all my functions:

import inspect, traceback, wraps

def vars(vars: dict, tab: int = 0):
    'Function for formatting variable output in Exception'
    s = ''
    for k,v in vars.items():
        if not k.startswith('__'):
            s += f'{' '*tab}{k}: {v.__repr__()}\n'
    return s.rstrip()

def log_traceback_locals(func):
    'Asynchronous decorator for logging local variables and calling the\exception again.'
    @wraps(func)
    async def wrapper(*args, **kwargs):
        try:
            return await func(*args, **kwargs)
        except Exception as e:
            log = telebot.logger
            stack = inspect.trace()
            for frame_info in stack:
                # Looking for the right frame with our function
                if frame_info.function == func.__name__:
                    locals_dict = frame_info.frame.f_locals
                    trace = traceback.format_exc()
                    trace_lines = trace.strip().split('\n')
                    # Trying to find variables where the error occurred
                    error_in_vars = {var: key for var, key in locals_dict.items() if var in trace_lines[-3]}
                    for key in error_in_vars.keys(): del locals_dict[key]
                    log.error(f"Exception: {e}"
                            f"\n{trace}"
                            f"\nLocal vars:"
                            f"\n{vars(error_in_vars, tab=4)}"
                            f"\n{vars(locals_dict)}")
                    break
    return wrapper

Then I just wrap all the functions with a message handler

@bot.message_handler(content_types=['text'])
@log_traceback_locals
async def alltext(m):
    local_var1 = 'string'
    local_var2 = 'wrong dict value'
    local_var2 in local_var1.keys() # Error

The output is as follows:

2025-01-09 13:26:30,394 (log.py:86 MainThread) ERROR - TeleBot: "Exception: 'str' object has no attribute 'keys'

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^

    local_var2 in local_var1.keys()
