[BUG]: Model::findFirst() result miss toArray method and Hydration Modes

[bain2018]

Describe the bug

$model=Model::findFirst();
$res=$model->toArray();
if i want to covert to array by toArray() ,i get an error:
Table '' doesn't exist in database when dumping meta-data for Model

doc https://docs.phalcon.io/4.0/en/db-models#hydration-modes

if i run this example
$model=Model::findFirst();
$model->setHydrateMode(
Resultset::HYDRATE_ARRAYS
);

the error is
The method 'setHydrateMode' doesn't exist on model

Details
Phalcon version:4.0 rc2
PHP Version: 7.3.11
Operating System: ubuntu

You need to check if your model is bound to the correct database table. Have a look at the initialize method of your model

class MyModel extends Phalcon\Mvc\Model
{
    public function initialize()
    {
        $this->setSource('database_table');
    }
}

The first error you get shows that you do not have a table defined there.

The findFirst returns back the model instance which indeed does not have the setHydrateMode in it. You can therefore use toArray() on it with optional field names passed (in the toArray) to get what you need.

If you have more results then you will get a resultset and setHydrateMode will return back arrays.
