Where ecommerce product description and title

I am trying to configure my ecommerce basket page:
/edx/app/ecommerce/ecommerce/ecommerce/templates/oscar/basket/partials/hosted_checkout_basket.html

The following fields are presented on the page:
line_data.image_url
line_data.product_title
line_data.product_description

However these fields are displayed None.

How can I set these fields so that they do not display None?
