registry product returns null

Question

My phtml file is extended with this class:

class Select extends \Magento\Catalog\Block\Product\View\Options\AbstractOptions
{
    protected $_escaper;  
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Framework\Pricing\Helper\Data $pricingHelper,
        \Magento\Framework\Registry $registry,
        \Magento\Catalog\Helper\Data $catalogData
      ) {
        $this->registry = $registry;
        parent::__construct($context, $pricingHelper, $catalogData);
      }
    private function getCurrentProduct()
    {
        if (is_null($this->product)) {
            $this->product = $this->registry->registry('product');

            if (!$this->product->getId()) {
                throw new LocalizedException(__('Failed to initialize product'));
            }
        }

        return $this->product;
    }

When i call my function $this->getCurrentProduct() i get nothing, what i am doing wrong here. Its a product page

Answer 1

This registry key will be filled only on the product detail page:

also, you may use

$this->registry->registry('current_product')

instead of

$this->registry->registry('product')
