Magento 2 product image is blank

Question

I'm trying to write an observer and send product data to external source.

Have everything done except that when I get image it shows default Magento image.

public function __construct(
    \Magento\Sales\Api\Data\OrderInterface $order,
    \Magento\Catalog\Model\Product $product,
    \Magento\Catalog\Helper\Image $imgHelper
) {
     $this->_order = $order;
     $this->_product = $product;
     $this->_imgHelper = $imgHelper;
}

public function execute(\Magento\Framework\Event\Observer $observer){
    ...
    $itemCollection = $order->getItemsCollection();
    foreach($itemCollection as $item){
        $product = $this->_product->load($item->getData('product_id'));
        $this->_imgHelper->init($product, 'product_thumbnail_image')->getUrl();
    }
    ....
}

The image which I get is:

http://convert.wemessage.it/magento2/pub/media/catalog/product/cache/dc09e1c71e492175f875827bcbf6a37

Do I miss something?

Answer 1

First please check whether product object is loaded successfully or not by fetching id using $product->getId() if product object is fine then Try to use this

$this->_imgHelper->init($product, 'product_thumbnail_image')->setImageFile($product->getFile())->getUrl();

instead of this

$this->_imgHelper->init($product, 'product_thumbnail_image')->getUrl();

I hope this will help

Answer 2
