Failure to display .pkpass event ticket from Entrytickets

Hi! I found this app when looking for a way to parse a .pkpass file I got from this website. It successfully imports into the app, and shows the correct name. However, when I tap on it, an empty page is shown with the error message:

GoException: no routes for location: /pass/[some ID]/[some longer ID]

On the web version, there is also a JavaScript error printed that may be related, which points me to https://gitlab.com/TheOneWithTheBraid/f_wallet/-/blob/main/lib/src/utils/pass_manager.dart?ref_type=heads#L91

Full JS stack trace

Uncaught : PKPassError: The PkPass file does not contain any web service.
