🚨 You probably want to use `session.exec()` instead of `session.execute()`.

This is the original SQLAlchemy `session.execute()` method that returns objects

of type `Row`, and that you have to call `scalars()` to get the model objects.

For example:

```Python

heroes = session.execute(select(Hero)).scalars().all()

```

instead you could use `exec()`:

```Python

heroes = session.exec(select(Hero)).all()

```
