setPodcastIndexChapterUrl Error

App version: 3.8.0f

Android version: 16

Device model: Pixel 6a

Expected behaviour: I’d like to add a podcast feed to my library

Current behaviour: When I try to add Free Cities Podcast, I get the following error:

The podcast host's server sent a broken podcast feed. We recommend checking with a podcast validator such as castfeedvalidator.com and contacting the podcast creator to let them know. 

Technical reason: 
Attempt to invoke virtual method 'void de.danoeh.antennapod.model.feed.FeedItem.setPodcastIndexChapterUrl(java.lang.String)' on a null object reference 

File URL:
https://feeds.fountain.fm/0Mh804AKI3yaq86kDWTp

The feed passes tests on both Cast Feed validator and Podbase validator.

First occurred: June 29 2025.

Steps to reproduce:

  1. Enter “Free Cities Podcast” in search
  2. Select “Search online”
  3. Click on the “Free Cities Podcast”

And what is the result of doing the check it suggests?

The feed passes the validation tests.
