I seem to randomnly get this error when searching a seller's inventory of more than a thousand or so albums. Here is the code snippet you can try ( just edit the line with the user_token )

Hey, @feacluster ! That code looks familiar 😄

What client version are you running? What about python version?

I tried with latest (2.3.12) and python 3.9. Also changed seller to "dingoacid" with around 5500 listings as the default one had no listings visible for me. And had no such errors.

Theres was a exponential backoff feature introduced in version 2.3.10 which should prevent these kinds of problems, try upgrading to that or latest if you havent allready.

[feacluster]

Thanks for the quick reply! Sorry, I am not sure why the seller rockdonkey is showing no listings now.. Anyways I checked and seems I am using version 2.2.2:

Python 3.6.8 (default, Nov 16 2020, 16:55:22)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import discogs_client
>>> print ( discogs_client.__version__)
2.2.2

I next tried:

 pip3 install --upgrade python3-discogs-client --user

But the version still showed 2.2.2:

Python 3.6.8 (default, Nov 16 2020, 16:55:22)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import discogs_client
>>> print ( discogs_client.__version__)
2.2.2

Seems like the discogs_client.__version__ hasnt been updated with the releases. https://github.com/joalla/discogs_client/blob/master/discogs_client/__init__.py Try command pip show python3-discogs-client

[feacluster]

Cool, yes it seems to show latest version using either pip show or pip3 show:

And it still produces that error? pip show seems to show version 2.3.5 while pip3 show is the latest, which command are you using when running the script (pip vs. pip3)?

[feacluster]

Just tested again and it seems to be working without any errors now. I am running it with python3 . I guess the python2.7 client is some older installation that I don't use.
