NoneType object has no attribute artists

[mybuntu-git2]

hi, I got a similar error to #4

(...)
  File "/usr/local/lib/python3.10/dist-packages/beetsplug/beatport4.py", line 600, in _get_album_info
    va = len(release.artists) > 3
AttributeError: 'NoneType' object has no attribute 'artists'

my beets setup is set to tag from scratch, and I move the 'artists' tag to 'artist' if that is not present, then I wipe 'artists' because the subsonic api reads artists first then artist if it is empty, which is kinda annoying as sometimes 'artists' is kind of unrelated to 'artist' which is usually the right one.
my preference would be, if some critical info is missing for beatport api to run, do not run it without crashing, but also have the artists-> artist fallback.

Hey @mybuntu-git2, thank you for spotting this one!

Could you please provide me some of these, so I can reproduce the issue and make sure I'll have it fixed?

• the deeper stack trace of an error
• the beet import command you are using
• related debug log starting with beatport4: (in such case, please remember to erase your credentials from the logs if present, before posting it)
  • debug level logs can be seen by adding -vv to the command beet -vv import ...

Hi @Samik081, sorry for crashing in. I can confirm this bug, I came across it a few times during the last days.
Here's a longer output including import command. Don't mind the debug print statements on the very top. They are there because I'm investigating something else, they might even help here or at least don't hurt, so I left them there:

beet import "/remote/data/music-library/DrumnbassJungleDrumfunk/0-Single-Tracks/Calibre - 0 - Inflicted _ Always - Always.mp3"

This is criteria
{'artist': 'calibre',
 'label': 'creative source',
 'release': 'inflicted / always',
 'tracks': '1'}

We were called from:
album_candidates
extra_tags is
{'label': 'Creative Source', 'catalognum': ''}

Does that help already? I can try tagging the same file and adding -vv if you want. HTH

@JOJ0 thank you for the stack trace, it was all I needed. :) Seems like Beatport API returns 403 for some releases, even though they present them in the /catalog/search result. This issue should be fixed by 76458c9, already in v0.2.10

[JOJ0]

Awesome! That was quick! Thanks!

[mybuntu-git2]

Thanks! really sorry for not providing the information myself, I lost track of this issue. I confirm that after updating best port with pip, the same files get correctly processed.
