Description

The NotFound exception originates from Flask/Werkzeug and is used to handle HTTP 404 errors in web contexts. It is unrelated to SQLAlchemy and will never be raised by a database query. As a result, the original exception block was effectively dead code. As a result, actual database errors (e.g., connection issues, statement execution failures) were not caught or handled properly.
