Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.After creating a node with a blank product reference field, I get the following 2 errors when viewing that node:
Notice: Undefined index: und in commerce_product_reference_node_view() (line 58 of /Users/tom/workspace/systemseed7/profiles/systemseed/modules/contrib/commerce/modules/product_reference/commerce_product_reference.module).
Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 167 of /Users/tom/workspace/systemseed7/includes/entity.inc).

I also applied the simple fix to check for a field value before attempting to load any products to avoid the undefined index error. I wonder if there's a better API to use for determining a field's value... will look into it.
