I have a try block which raises an exception every time, in except block I used logging.exception('some message') to log error. But while handling the above exception another exception occurred.
try:
raise Exception('')
#some key error exception raised.
except Exception as e:
abortMsg = "some error"
logging.exception(abortMsg)
return
I'am pretty sure that the error is caused by the stack trace of the exception,Any operation related to it like printing it , or using traceback.print_exc() raises exceptions recursively
The error log when i used traceback.print_exc()
Error log:

Is there any way to see and analyse stack trace which is causing error?
PS : I'm using this inside a docker. While i run this file locally no recursive exception is raised.
EDIT : Any exception raised from anywhere from the code is causing recursive exception(unicode decode error)

I'm trapping thus:
with httpx.Client(**sessions[scraperIndex]) as client:
try:
response = client.get(...)
except TimeoutError as e:
print('does not hit')
except Exception as e:
print(f'⛔️ Unexpected exception: {e}')
print_exc() # hits!
However I'm getting the below crashdump.
Pulling out key lines:
TimeoutError: The read operation timed out
During handling of the above exception, another exception occurred:
httpcore.ReadTimeout: The read operation timed out
The above exception was the direct cause of the following exception:
httpx.ReadTimeout: The read operation timed out
Why isn't my TimeoutError catching this?
And what's the correct catch? Can someone give a logic for deducing it?

httpx.ReadTimeout: The read operation timed out
The base class for all httpx timeout errors is not the built-in TimeoutError (presumably because that would also make timeouts OSErrors, which doesn't sound correct), but httpx.TimeoutException.
import httpx
with httpx.Client() as client:
try:
response = client.get("http://httpbin.org/get", timeout=0.001)
except httpx.TimeoutException as e:
print('gottem')
prints gottem just fine.

Here is a piece of my code:
from tweepy import StreamListener
from retrying import retry
import tweepy
#retry
class MyStreamListener(StreamListener):

def on_status(self, status):
do something ...
except Exception as e:
pass
myStreamListener = MyStreamListener()
myStream = tweepy.Stream(auth=twitter_handler.api.auth, listener=myStreamListener)
myStream.filter(track=['#Something'])
I found these "#retry" here but apparently, it doesn't work properly.

You have bad syntax here:
email.attach_file=(f"/store/{file}")
attach_file() is a method, and you're assigning to it with = which means the method gets replaced on the object instead of being called. Change it to:
email.attach_file(f"/store/{file}")
