sys.exit() triggers TypeError: object of type 'NoneType' has no len() error

Question

I can not make my script stop. I've tried sys.exit () as well as os._exit()

I have a bit of the code:

try:

        report  = func_timeout(config.timeout_time, load_the_report, args=(download_id, config))

    except FunctionTimedOut: 
        print(f"timeout error for the {config.name} {config.date}")
        print('####')
        sys.exit()

sys.exit () gives an error :

SystemExit: 

During handling of the above exception, another exception occurred:

TypeError                                 Traceback (most recent call last)

TypeError: object of type 'NoneType' has no len()

os._exit() worked but it does not print at what line the timeout happened

if I am not quitting the script it errors further, where the report is meant to be created (missing variable). I don't know what is wrong with this
