Hey @nick-youngblut, you probably want to implement a destructor method like __del__ for your class AsanaReader() the client library has it's own destructor https://github.com/Asana/python-asana/blob/master/asana/api_client.py#L93C9-L96

class AsanaReader:
    def __init__(self, asana_token: str=None) -> None:
        """Initialize Asana reader."""
        config = asana.Configuration()
        config.access_token = asana_token
        self.client = asana.ApiClient(config) 

    def __del__(self):
        ...

reader = AsanaReader(asana_token=os.getenv("ASANA_PROD_API_KEY"))
del reader

I think a check for self.pool is not None in the destructor would probably also help with your script: https://github.com/Asana/python-asana/blob/master/asana/api_client.py#L93C9-L96

You can add that check in the template that generates the ApiClient code here: https://github.com/Asana/python-asana/blob/master/codegen/templates/api_client.mustache#L88-L91 and send a PR

EX:

def __del__(self):
    # Safeguard the closure of the pool
    if hasattr(self, "pool") and self.pool:
        try:
            self.pool.close()
            self.pool.join()
        except Exception as e:
            # Capture and log any exception that arises during cleanup
            logging.error(f"Error in __del__: {e}")
