Description

While a product in the shopping config must have a productImages key according to the JSON schema (see #36460), it is technically not required to have any images. So an empty productImages array does not fail validation.

However, it causes an uncaught TypeError in this code here that expects at least 1 image to exist:

Reproduction Steps

1. Add amp-story-shopping configuration with at least two products, where at least one product does not have any images, i.e. productImages = []
2. Click on the shopping attachment
3. See error in console and that the attachment does not open

In my testing it somehow worked on the first page, but the error was always thrown
