This means that the method $block->getLoadedProductCollection() returns null.

I think you are using this template with a block that does not contain the method getLoadedProductCollection. So it falls back to $block->getData('loaded_product_collection') that is null.

Make sure the block you are using at least extends the block below:

\Magento\Catalog\Block\Product\ListProduct`

  • should I extends block to \Magento\Catalog\Block\Product\ListProduct in phtml or in ListProduct.php ? Any help is really appreciated. Thank you. Mar 9, 2017 at 16:17
  • I think you should post more details by editing the question about what are you trying to achieve. I just made some assumptions in my answer.
