Points and Contacts in cardTemplateOverride not visible

Following the documentation creating a pass works but the additional text fields are missing (points and contacts) on the pass. Instead the texts are shown on "the back" of the pass e.g. when you open the details page.

I also can't see what the textModulesData { 'header': 'Gather points meeting new people at Google I/O', 'body': 'Join the game and accumulate points in this badge by meeting other attendees in the event.', 'id': 'game_overview' } is about.

Start by running the web-codelab sample that creates a pass and inspect the cardTemplateOverride configuration alongside the rendered pass. Check how the points, contacts, and textModulesData entries are presented, then verify that the intended text appears in the expected pass location and that the behavior is covered by the sample documentation or its available checks.
