Describe the bug
I have tried earlier versions of the script (v5) and the latest and both seem to have the same issue.
I use the standard set of containers in the compose file, except for switching out mariadb for a mysql container running 5.7 to mimic a dated live production server.
The website runs well if not slow until you log into the backend of drupal where it will complain about automated_cron does not exist.
Happens when trying to go to configuration from the menu.

This is an old drupal 8 site which has been upgraded through time to drupal 9.

This site works out of the box with xampp apache and mysql, no issues with automated cron
