The property attribute_casting does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.

            ? array_merge(get_ancestor_property(get_called_class(), 'attribute_casting'), $attribute_casting)
            : $attribute_casting;

        $this->casts_booted = true;
    }
