Error communicating with Twitch API ('NoneType' object is not subscriptable)

[r3-l5-r3]

Just updated via the AUR to the most recent release; twitchy crashes when trying to check channel statuses (e.g. by just executing twitchy) , with this error:

Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/twitchy/twitchy_api.py", line 260, in get_game
    'EQUALS')[0]
TypeError: 'NoneType' object is not subscriptable

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/twitchy", line 11, in <module>
    load_entry_point('twitchy==3.1.0', 'console_scripts', 'twitchy')()

    game_name = game_details[0][1].replace("'", "")
IndexError: list index out of range

(Aside: I don't know if this is intentional, but AUR package version numbers and git release commit numbers aren't consistent, threw me off for a bit; e.g. AUR package r31.38f8c54-1 retrieves release r185.214c8c0-1 from the git repo.)

Hey,

I've only been able to replicate this in case of the function that's erroring out being fed an invalid game_id. Now that's something that reported by the API itself. So this shouldn't be happening.

Therefore, I'm going to need a little more information. The fastest way about that is putting a

print(r.url)

as line 28 of the twitchy_api module. Or use this patch here: https://pastebin.com/8m77WAbd It would also really help if you would include a copy of your twitchy.db from ~/.config/twitchy3/twitchy.db

[BasioMeusPuga]

The AUR version thing was an oversight. Didn't make too much of it since those numbers update by themselves. That's fixed.

[r3-l5-r3]

So I've checked just now, seems like the error has gone away (possibly due to the invalid game_id no longer being a thing?), and I can use the API with twitchy as normal.

Just for reference, I've added the print line manually to the twitchy_api module, and here's what's output from running twitchy:

 Number? 

Here's my database file (I've compressed it to a .gz file to comply with GitHub's restrictions on file uploads for threads): twitchy.db.gz

Sorry for not replying earlier; I'll check again later to see if the problem re-appears. I've also updated my twitchy installation again via AUR to match version numbers, but that shouldn't be relevant to the above issue, I'm guessing.

[r3-l5-r3]

Wait, I am getting a somewhat different error though. I'm unable to use twitchy -w <channel> to open streams; the following comes up when I try to open a stream (that is currently online) this way (e.g. twitchy -w nusuey):

https://api.twitch.tv/helix/users?login=n&login=u&login=s&login=u&login=e&login=y
 No valid channels.

...I don't know if this is related to the above issue, but it is an issue that I did have earlier on as well (sorry, forgot to mention this earlier).

EDIT: Also worth noting, using twitchy --non-interactive kickstart <channel> does load the stream and open the browser chat popout as normal.

[BasioMeusPuga]

So I checked your twitchy.db file. One of the game names is blank. This happens when a streamer does not set a game name for whatever reason. I'm assuming that is what was getting passed to the function which was causing it to get a null return, and therefore to error out.

The -w thing is fixed.

Tell me if this changes anything or the errors return?

[r3-l5-r3]

Replaced the __main__.py and twitchy_api.py with the newest version that includes your fixes, and it seems to be handling it correctly. I can't tell for sure, since it seems like none of the channels in the database haven't set a game name (at this point in time).

Can confirm the -w thing is fixed. Thanks for helping me out with the issues; I'll report back if I see them reappear again for whatever reason.
