Cursor does not find rows in database

Hello all.
I am trying to create my first script for the OLX app.
The problem is that the cursor does not see the rows in the database. I understand that there are columns with JSON, but I will implement this later, and for now the cursor simply does not see the rows, and they are there. I wrote several checks, but they all return 0.

I tried enclosing the column names in both ' and ` but the result is the same.

Can anyone tell me what the problem might be?
