If you use custom requests for validation, for replace data for validation, or to set default data (for checkboxes or other) use override method prepareForValidation().

namespace App\Http\Requests\Admin\Category;
    
class CategoryRequest extends AbstractRequest
{
    protected function prepareForValidation()
    {
        if ( ! $this->get('url')) {
            $this->merge([
                'url' => $this->get('name'),
            ]);
        }
        $this->merge([
            'url'    => \Str::slug($this->get('url')),
            'active' => (int)$this->get('active'),
        ]);
    }
}
