Django application logs are not rotated

In a Django application, version 3.2.14, running on an ec2 instance that also has a gunicorn web server with 9 workers, plus ngnix and with the log configuration shown below, the files are not rotated.

The user of the gunicorn service is ubuntu and belongs to the group: www-data

What could it be? Is there an issue with gunicorn and the workers?

I appreciate your answers.
