Hello.

Not sure exactly when it started happening, but the YTMusic client returns empty list [] when calling:
get_library_upload_songs
and
get_library_upload_artists

(using different limit param values does not have any impact)

Actually, my lilbrary of uploaded songs/artists constains more than 1000 songs and more than 300 artists.
When I use the browser, I can find/play them without any problem.

For the empty list problem, when I set a breakpoint, I can see the problem is around these lines in code of the method:

     43         if order is not None:
     44             body["params"] = prepare_order_params(order)
     45         response = self._send_request(endpoint, body)
---> 46         results = get_library_contents(response, MUSIC_SHELF)

The response variable has a lot of content:

ipdb> response
{'responseContext': {'serviceTrackingParams': [{'service': 'GFEEDBACK', 'params': [{'key': 'browse_id', 'value': 'FEmusic_library_privately_owned_tracks'}, {'key': 'browse_id_prefix', 'value': ''}, {'key': 'logged_in', 'value': '1'}, {'key': 'e', 'value': '1714252,23804281,23882685,23918597,23934970,23946420,23966208,23983296,23998056,24001373,24002022,24002025,24004644,24007246,24034168,24036947,24077241,24080738,24120820,24135310,24140247,24161116,24162920,24164186,24169501,24181174,24187043,24187377,24191629,24197450,24199724,24200839,24209350,24211178,24216167,2421
....

But results, which is the returned value of get_library_contents using the previous response, is None:

ipdb> results is None
True
ipdb> l
     42         validate_order_parameter(order)
     43         if order is not None:
     44             body["params"] = prepare_order_params(order)
     45         response = self._send_request(endpoint, body)
     46         results = get_library_contents(response, MUSIC_SHELF)
---> 47         if results is None:

Something similar happens with uploaded artists:

ipdb> self.client.get_library_upload_artists()
[]

As I said, getting an uploaded artist individually works fine:

ipdb> self.client.get_library_upload_artist("FEmusic_library_privately_owned_artist_detaila_XXXXXXXXXXXXXX")
[{'entityId': 't_po_HHHHHHHHHHHHHHH', 'videoId': 'YYYYYYYYYYYYY', 'title': '......

Any idea what is happening here?

I have tried to use the latest commit on master branch, but it fails the same way.

Using v0.23.0 returns a different error

  File "/mypath", line 128, in get_songs
    return self.client.get_library_upload_songs(limit=config["song"]["limit"])
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File "/hmypath, line 46, in get_library_upload_songs
    results = find_object_by_key(nav(response, SINGLE_COLUMN_TAB + SECTION_LIST),
                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File "/mypath", line 74, in nav
    raise err

  File "/mypath", line 68, in nav
    root = root[k]
           ~~~~^^^

KeyError: 'contents'

My environment is:

Ubuntu 22.04.1 LTS
YTMusic API v0.24.0
python 3.11

Thanks a lot.

The mentioned endpoints are working fine for me. Are you sure your credentials haven't expired?

If that's not the case I can try reproducing the issue with your credentials, if you don't mind sending them to ytmusicapi@gmail.com.

@sigma67 Thanks a lot for the reply and sorry for my late response.

Are you sure your credentials haven't expired?

In all fairness, I am not 100% sure. In fact, it is true that my credentials expired a while ago, and I created a new headers json file with new ones, but maybe that is not working fine, somehow.

However, if the problem is related to my credentials, then:

how is it possible that I get an authenticated client instance successfully every time?
how is it possible that I can call get_library_upload_artist method using that authenticated client and get the right result?

The problem only shows when calling get_library_upload_songs and get_library_upload_artists.

Here is a REPL session showing the above:

In [1]: from ytmusicapi import YTMusic

In [2]: client = YTMusic("youtubemusic/config/headers_auth.json")

In [3]: client
Out[3]: <ytmusicapi.ytmusic.YTMusic at 0x7ffa598e2b90>

In [4]: client.get_library_upload_songs(limit=100)
Out[4]: []

In [5]: client.get_library_upload_artists(limit=100)
Out[5]: []

In [8]: client.get_library_upload_artist("FEmusic_library_privately_owned_artist_detaila_po_CIOIo7OKzretmwESA3Vmbw")
Out[8]: 
[{'entityId': 't_po_CIOIo7OKzretmwEQuqXj1f7_____AQ',

  'title': 'Doctor Doctor',
  'duration': '4:03',

  'album': None,

  'thumbnails': [{'url': 'https://www.gstatic.com/youtube/media/ytm/images/cover_track_default@1200.png?sqp=CPXnx-oF-oaymwEGCDwQPFgB&rs=ALLJMcKG4HoG-nDcHAjjtvKnA1-TsHbplA',

    'width': 120,
    'height': 120}]}]

Anyway, I suspect that somehow you are right and my problem is a credentials problem.

I will send you my credentials to your private email account ....

Thanks.

I was able to verify that your credentials are valid and that you are indeed getting an empty list even though you have uploads. Will look into a fix.

@sigma67
I have pulled the latest commit on your main branch:
( 0.24.1.dev5+g2344a17 d0ec2bb)
I presume the commit for your fix (02e3289) is a parent of the tip commit above...

And yes, the fix works perfectly.
I have been able to get all songs and artists I have already uploaded to the server.

Thanks a lot for the quick fix.

Is there an ETA for this to be released?

Thanks.
