Just got the same error; although seems to be a transient error. Rerunning, I was able to successfully create the playllist.

Can you identify the specific song that is causing the issue? You can perhaps add a print statement in the source code before each search query. This would actually be an upstream issue with ytmusicapi.

As far as I could tell it was never any specific song. It failed at a different spot every time

@kler commented on GitHub (Aug 25, 2023):

I can confirm that the error is present within ytmusicapi 1.2.0.

As visible in the stack trace this comes from get_item_text() in ytmusicapi\parsers\_utils.py

I tried the migration several times, and failed at different points, so it's not consistent for a certain song for instance.
The error depends on the data returned from Youtube Music, making ytmusicapi crash.

Code analysis

Looking at the variable called column in get_item_text() in the debugger, it only has the 0:th index, while the calling function calls it with a hard coded index of 2:
search_result['name'] = get_item_text(data, 1, 2) (link to code)

image

In case it would be acceptable to ignore the missing entry, there is a param called none_if_absent, however this is not passed from the caller function, meaning that the bug itself is actually in the ytmusicapi, and not in its utilization in spotify_to_ytmusicAFAICT.

I've tried setting none_if_absent=True in the caller function parse_search_result() line 80, and does indeed make it work, but I have no idea what side effects it has or if I'm breaking some intended behaviour.

I also had a similar error in parse_menu_playlists() (link to code)
where it calls nav(), which fails in the item called menu.
I tried setting none_if_absent=True here as well, and it made the playlist creation succeed.

So I'm trying with some pretty large playlists right now but failing to reproduce. It might be something specific to your accounts or a very rare bug where the name is missing on a profile result.

It would be very helpful if you could add the following debugging code to your local ytmusicapi installation and paste the output data here whenever you see the issue. Instead of this line

github.com/sigma67/ytmusicapi@6660058a47/ytmusicapi/parsers/search.py (L80)

add

        search_result['name'] = get_item_text(data, 1, 2, True)
        if search_result['name'] == None:
            print(data)
            sys.exit()  # optional to stop when you find the issue

Managed to reproduce. I figure it's safe to ignore the value if absent since there are no other flexitems on this type of search result (yet).

Great, thx!

I also made a run with the changes you proposed, and this is the result:

There is unfortunately also a second problem in the nav() function in navigation.py - but didn't store the stack trace from when I had the error. Will possibly come back with that in another bug report if I hit it again.
