Additional information

I have a suspicion that this issue is identical to #10778. The stack trace both resolve to the same Null Pointer Exception: Caused by: java.lang.NullPointerException: (info as? ChannelInfo)?.…?: subscription.avatarUrl must not be null issue.

The fact that #10778 is caused by a failure to fetch a blank avatar from a YouTube subscription, and in this case the same exception is thrown on a PeerTube channel might indicate that there need to be more robust extractor methods to handle this scenario in the future especially if it turns out to be a cross service issue.

thank you so much for your time and beautiful work!!
