How to transform to the correct type?

[francoism90]

I'm using Livewire, this is my PostData object:

class PostData extends Data implements Wireable
{
    use WireableData;

    public function __construct(
        public Optional|string $id,
        public Optional|null|Carbon $published_at,
    ) {
    }

    public static function fromModel(Post $model): self
    {
        return new self(
            id: $model->getRouteKey(),
            published_at: $model->published_at,
        );
    }
}

Blade:

<input type="datetime-local" wire:model="post.published_at">

Result:

Cannot assign string to property PostData::$published_at of type Spatie\LaravelData\Optional|Illuminate\Support\Carbon|null

I could add string as type, however this causes multiple types, which isn't nice.

How can I make sure it always returns a Carbon or DateTime value?

Thanks.
