Answer

Solution:

You need to tell Eloquent that the field is a date field, with the dates value. This will convert any field specified to a Carbon object. Add this line to the top of your model class.

protected $dates = ['start_at'];

https://laravel.com/docs/8.x/eloquent-mutators#date-casting

protected $casts = [
    'start_at' => 'datetime:Y-m-d H:i:s',
];
