[bug] search filtered by videos now may include podcast/episode which throws an error

[lovegaoshi]

I recently bumped into some failed to parse cases at libmuse/script/parsers/search.js's parse_search_song
reproducible with

search("wake", {
      filter: 'songs',
    }),

the navigationEndPoint returns browseEndpoint instead of watchEndpoint:

If it's returning a browseEndpoint instead of a watchEndpoint, that means it's not a song at all. maybe it's a podcast (because of the MUSIC_PAGE_TYPE_NON_MUSIC_AUDIO_TRACK_PAGE??

In this case, podcasts aren't supported yet, and I'm not sure why YTM is returning podcasts when you are searching for songs anyway.

I can't actually reproduce this because for me everything works correctly... you can try to compare what gets returned when you search for that on music.youtube.com

thanks for the quick response! YT changed their search priorities and above code works fine just hours later, and I found another reproducible code:

search("don't wake up", {
  filter: "videos",
}).then((v) => console.log(v.categories[0].results));

happens in filter videos not songs, my apologies. exact same error msg

[vixalien]

working for me...

can you tell me what happens when you search for that at https://music.youtube.com? do you get podcast results when you filtered for videos??

[lovegaoshi]

you are abs right, it is indeed a podcast that shows up when filtering for video. guess ytm finally made that push after google podcast deprecation

to be faster, you can just clone this repo and edit the client.ts file and then run it with deno task start.

you are abs right, it is indeed a podcast that shows up when filtering for video. guess ytm finally made that push after google podcast deprecation

well the folks at YTM are bizarre. anyway, I guess the actual solution would be to add support for podcasts and episodes.

[lovegaoshi]

or we can try-catch wrap parse_search_song and call it a day for now ;)

[vixalien]

yes we can.
