Schedule Python script with crontab doesn't work

Trying to schedule a python code in crontab, but it doesn't work. How Can I understand the reason why? I've already add cron and termianl to Full disk access, so this shouldn't be a problem

everything works fine when I run in terminal command python /users/myuser/slots_update.py

Crontab command which doesnt'work: 45 12 * * * /usr/bin/python /users/myuser/slots_update.py

Python script (put different sql inside to make it simplier)
