YouTube Playlist.info.json file causes error if there are private videos in a playlist

[noemartinez]

Platform

Operating system and version: Ubuntu 24.04
Plex version: 1.42.1.10060

Expected Behavior

Playlist information should be loaded from Playlist.info.json even when there's some private videos (which apparently show up as null entries) in the YouTube playlist.

Current Behavior

The scanner crashes due to null entries in the JSON file

Steps to Reproduce

1. Inside the playlist folder, write the playlist info JSON file for this playlist which has 2 private videos yt-dlp --dump-single-json 'https://www.youtube.com/watch?v=5bRfSzbdfcU&list=PLJ49NV73ttrtNfEURR5YrckZsdDjniSjT' > Playlist.info.json
2. Write out the episodes with yt-dlp --write-info-json -o '%(upload_date>%Y_%m_%d)s - %(title)s - [%(display_id)s].%(ext)s' 'https://www.youtube.com/watch?v=Eqin7y9_-IQ&list=PL_0BB1yzZzOe2-MgLE0npPnjgl-jDBW1i'
3. Add the library to plex, and notice this error in /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Logs/Plex Media Scanner.log:
