boto3 GetObject and HeadObject Failure with python_wrapper

[SiviP-Glossai]

I am running a simple python server, with no framework, calling @epsagon.python_wrapper over the main function.
I use boto3 to make Put/Get/Head operations on an S3 bucket. Only Put operation registeres in the traces

I ran with debug and got the following error for each Head/Get:

[EPSAGON_DEBUG] Epsagon exception: Invalid format string
Traceback (most recent call last):
  File "C:\Git\Production2\glvideo\.venv\lib\site-packages\epsagon\modules\general_wrapper.py", line 35, in wrapper

    response['LastModified'].strftime('%s')
ValueError: Invalid format string
-----

The bug seems to be you are using:
response['LastModified'].strftime('%s')
Instead of:
response['LastModified'].strftime('%S')

Hi @SiviP-Glossai, as discussed on Intercom, the issue didn't reproduce on our side.
The versions used to reproduce are:
Python - 3.8.0
Epsagon - 1.79.0
Boto3 - 1.24.2

Please check if it happens when Epsagon is disabled (by using the environment variable DISABLE_EPSAGON and setting it to True, then re-run it).
In case it won't happen, please share a code snippet.
Thanks.

This is system dependant. See: https://stackoverflow.com/questions/11743019/convert-python-datetime-to-epoch-with-strftime
They say it is not recommended to use %s as it is not documented and will not work for all systems.
I am using Linux Alpine Docker in my case.
