Where did you find this the npm-demos.appspot.com link? I'm guessing it's because that service doesn't serve JSON files because they're definitely included in the published NPM package (https://unpkg.com/@polymer/[email protected]/demo/data/contacts.json).

From Google search, initially, the landing page is actually https://www.webcomponents.org/element/polymerelements/iron-list

But the UI redirects it to the @polymer npm package. As a result, the (first) demo link doesn't work: https://raw-dot-custom-elements.appspot.com/polymerelements/iron-list/v3.0.2/iron-list/demo/cards.html That link is broken too, with

cards.html:1 Uncaught TypeError: Failed to resolve module specifier "@polymer/polymer/polymer-legacy.js". Relative references must start with either "/", "./", or "../".

Then, on a reload of the @polymer URL, there's a different issue (the one that I originally filed here).
