I’m new. I need some help. I got my flask app with some error on production. Works locally, but on production gives me server overload error. Where do i can find error log(only python code, should i write some javascript?). How is the best way to do it. How to check errors more specific than fuk you it doesnt work. Is there any example how to do it?

I want to use PostgreSQL in Python Flask, but I want to create tables and perform checks with SQL queries without using ORM, is this possible?
