Error message in Docker logs with all successful responses

I am running Flask inside of a python-based Docker container. I've observed the following error whenever I make a request:

INFO:werkzeug:172.20.0.1 - - [25/Feb/2025 05:42:42] "OPTIONS /api/v1/account/details HTTP/1.1" 200 -

This occurs after every request is made to my backend, whether it is successful or not.

Originally, I had thought that the error was a result of my CORS policy being too loose, so I made it stricter, but saw the same issue. I have CORS policy set up as follows:

CORS(app, 
        resources=
            {r"/api/*": {
                            "origins": ["http://localhost:3001"], 
                            "methods": ["GET", "POST", "PUT", "DELETE"], 
                            "allow_headers": [
                                "Content-Type", 
                                "Authorization", 
                                "X-CSRF-Token", 
                                "X-CSRFToken", 
                                "x-csrftoken"
                            ],
                            "supports_credentials": True
                        }
            }
    )

However, the ERROR:root still appears even with a stricter CORS. Any ideas as to what is causing this message in the Docker logs?
