[Bug] SpotifyToYouTubeEnricher Crash: ArgumentNullException in YouTubeMusicAPI (buttons[2] token null)

Bug Description

I am running the develop branch of Tubifarry on Lidarr v3.1.1.4884. When performing a search (either interactive or automatic), the plugin successfully finds potential matches on YouTube Music (retrieving the Album IDs correctly), but the SpotifyToYouTubeEnricher crashes immediately when attempting to fetch the album info.

The error suggests that the parser in the YouTubeMusicAPI dependency is looking for a specific token (playlistId) within buttons[2], which appears to no longer exist or has moved in the YouTube Music DOM.

Steps to Reproduce

1. Add Tubifarry indexer (Develop branch).
2. Search for an album (e.g., "Haunting" by "Braeker").
3. Check debug/trace logs.
4. Observe that YouTube album IDs are found, but enrichment fails for every result.

Expected Behavior

The plugin should parse the YouTube Music album page, retrieve the tracklist/bitrate, and add the release to Lidarr.

Additional Context

It appears the YouTubeMusicAPI library is hardcoded to look for the "Play" button (or similar navigation element) at index [2] of the buttons array in the JSON response.

The logs confirm the Album ID is found (OLAK5uy_m5xu1Nutm-vFisLC9Fne8uRnqhjI0_f_k), but GetAlbumInfoAsync fails to parse the resulting page data. This likely indicates a change in the YouTube Music website structure.

I will look into it, as soon as I have time.

I’m unable to reproduce this issue on my end. Could you share more details about your setup?

• Have you installed Node.js?
• Did you configure the cookies properly?
• Is it possible that your IP address is being blocked?

At the moment, I just can’t seem to encounter this problem myself.
