Plugin doesn't start due to exceptions.AttributeError: CookieJar instance has no attribute 'copy'

[ronajon]

since a couple of days i can't browse Google Music anymore.
in the server.log this message appears

[14-03-22 19:53:43.4525] Slim::Utils::PluginManager::load (348) Warning: Couldn't call Plugins::GoogleMusic::Plugin->initPlugin: exceptions.AttributeError: CookieJar instance has no attribute 'copy' at line 106

I must admit that I've never seen this error. A bit of googling tells that this is probably Python related. A first thing would be to update gmusicapi to the developer version:

sudo pip install git+https://github.com/simon-weber/Unofficial-Google-Music-API.git@develop

You could also try to update the Perl Inline and Inline::Python module:

sudo cpan App::cpanminus
sudo cpanm --notest Inline
sudo cpanm --notest Inline::Python

Does this help?

[ronajon]

updated the gmusicapi and executed the perl commands.
both did not work.

i just reinstalled logitechmediaserver, added the google music plugin, but still the same error

[ronajon]

also tried updating all perl modules, didn't resolve the issue either

[hechtus]

I have no clue. Do you have any idea what has changed when the error occurred? What kind of system do you have? What are the LMS and Google Music Plugin versions?

@simon-weber Do you have an idea what the exception below is all about?

AttributeError: CookieJar instance has no attribute 'copy' at line 106

[simon-weber]

I don't think I ever try to copy a cookiejar. My bet would be that this is a bug in requests.

@ronajon can you show us the output of pip freeze? You might also try just installing requests 2.1.0 explicitly; that's the last known-good version (simon-weber/gmusicapi#217).

[ronajon]

i had requests 1.2.0, and after upgrading to 2.2.1 the problem is solved!

Glad it works! I'll make a note to test on requests 1.2.0 -- if it always breaks, I can blacklist it.

@simon-weber Thanks for your help!

@ronajon Great that it works now and thank you for reporting this issue. I suspect it's closed now ...
