Cannot get a custom cast to work

[abishekrsrikaanth]

Here is my custom cast class

use Spatie\LaravelData\Casts\Cast;
use Spatie\LaravelData\Casts\Castable;
use Spatie\LaravelData\Support\DataProperty;

class TransitSubStatusCast implements Castable
{

    public function __construct(public mixed $transitSubStatus)
    {
    }

    public function status()
    {

    }

    public static function dataCastUsing(array $arguments): Cast
    {
        ray($arguments);
        return new class implements Cast {

            public function cast(DataProperty $property, mixed $value, array $context): mixed
            {
                ray($context);
                return new self($value);
            }
        };
    }
}

and here is how I am casting the argument on the constructor

use App\TransitSubStatusCast;
public function __construct (
        #[WithCastable(TransitSubStatusCast::class)]
        public TransitSubStatusCast $transitSubStatus,
) {
}

Here is the error I am getting

TYPE ERROR  Too few arguments to function TransitSubStatusCast::dataCastUsing(), 0 passed in vendor/spatie/laravel-data/src/Attributes/WithCastable.php on line 29 and exactly 1 expected 

can you please advice if I am missing something here?

Always follow the docs correctly, your dataCastUsing method signature was incorrect:

it('will work', function (){
    class TransitSubStatusCast implements Castable
    {

        public function __construct(public mixed $transitSubStatus)
        {
        }

        public function status()
        {

        }

        public static function dataCastUsing(...$arguments): Cast
        {
            ray($arguments);
            return new class implements Cast {

                public function cast(DataProperty $property, mixed $value, array $context): mixed
                {
                    ray($context);
                    return new TransitSubStatusCast($value);
                }
            };
        }
    }

    class DataBlaBla extends Data{
        public function __construct (
            #[WithCastable(TransitSubStatusCast::class)]
            public TransitSubStatusCast $transitSubStatus,
        ) {
        }
    }

    dd(DataBlaBla::from(['transitSubStatus' => 'a']));
});
