So I chose to implement logging in my discord.py bot which is fine and dandy and works alright. but once I add logging to files, be it through using a filehandler
handler = logging.FileHandler(
filename="../logs/bot.log",
mode="a")
formatter = logging.Formatter("%(asctime)s %(name)-30s %(levelname)-8s %(message)s")
handler.setFormatter(formatter)
handler.setLevel(logging.DEBUG)
logging.getLogger().addHandler(handler)
Or through the basicConfig
logging.basicConfig(filename="../logs/bot.log", filemode="a", format="%(asctime)s %(name)-30s %(levelname)-8s %(message)s", level=logging.DEBUG)
I always get this Traceback on exit
Exception ignored in: <function ClientSession.__del__ at 0x7fe1330b9790>
Traceback (most recent call last):

I'm utterly stumped as to what did wrong as the Traceback doesnt include any of my own files. I'm suspecting I might have to do some manual cleanup but even if I do logging.shutdown() I get the same Traceback

The Python "NameError: name is not defined" occurs when we try to access a variable or function that is not defined or before it is defined. To solve the error, make sure you haven't misspelled the variable's name and access it after it has been declared.
To specifically handle NameError in Python, you need to mention it in the except statement. In the following example code, if only the NameError is raised in the try block then an error message will be printed on the console.
What Is a NameError in Python? In Python, the NameError occurs when you try to use a variable, function, or module that doesn't exist or wasn't used in a valid way. Some of the common mistakes that cause this error are: Using a variable or function name that is yet to be defined.
That is because something (asyncio in this case) tries to log during the shutting down phase of the interpreter.
This is a known problem. A workaround for the logging module has been implemented in python 3.10
It happens because the name open has already been deleted by the garbage collector before the file handler got the time to use it.
You can avoid this problem by trying to explicitly close/release your resources before your program exit.
