$_product->getUrlKey() returns empty

[Jaime Stuardo]

Hello,

I need to get url_key attribute of a product, but I cannot. 

I am calling this:

<?php 
$_helper = $this->helper('Magento\Catalog\Helper\Output');
$key = $_helper->productAttribute($_product, $_product->getUrlKey(), 'url_key')
?>

$product is an element of $_productCollection = $block->getLoadedProductCollection();

However, $key get empty. Of course, url key was entered in backend and I do see it in database also.

Any help will be appreciated.

Thanks

Jaime

Why do not you just use $_product->getUrlKey() instead of your 2 lines of code?

getUrlKey does not seem to work. Any other ideas?
