What happened?

I have set logging. getLogger ('apscheduler '). setLevel (logging. DEBUG), and it will be executed last from 07:20:00 on February 21, 2024. After that, the task will not be executed, and the service can still be accessed normally. I am using FastAPI. No abnormalities were found in the logs, and the obtained logs are as follows:
