I am using this tutorial (Dash CRUD App with PostgreSQL - Part 2 - YouTube) to connect to my postgres db and retrieve some table.
I now want to export my table in csv file but I’m getting “A nonexistent object was used in an State of a Dash callback”
when I run the application. Now, I am new to Dash and a bit confused, I understand that State does not trigger callback, so why is it triggering this error? The error gets triggered on table object.
