Hi,

I'm testing version 0.13.1

and when I query 'dinosaur jr'
I'm getting

I cannot reproduce unfortunately. Can you pinpoint which search result is causing this? Are you using an authenticated instance?

Thanks for the quick reply.
I'm getting the error with this code

from ytmusicapi import YTMusic
ytmusic = YTMusic()
results = ytmusic.search("dinosaur jr")

I'm using an unauthenticated instance

These are my results for that search term, unauthenticated (JSON below). Thumbnails removed for brevity. They might be different from your location. Do you see any unusual songs in your song/video results that don't appear in mine? Unusual would mean that some subtitles are odd or missing. You can check using the web interface if ytmusicapi breaks.

@sigma67 commented on GitHub (Jan 28, 2021):

So this one's due to an unavailable song which is missing the typical Song •.

@chaos87 can you confirm that there is also an unavailable song in your search result? Just to make sure it's the same issue.

Edit: If it was the same issue, it should no longer crash with latest master.

I'm not sure what is an unavailable song or how to identify it. By the past I saw songs results with missing videoId, but the search wouldn't break (and also in 0.13.1).

I can include a more detailed traceback, hope that can help

At this point it would be most helpful if you could update to master using pip install -U git+https://github.com/sigma67/ytmusicapi and check if that fixes the issue.

By the past I saw songs results with missing videoId, but the search wouldn't break (and also in 0.13.1).

Those would be the unavailable ones. I think it's breaking again now because of some other bugfixes made in the meantime, but might also be a YouTube update
