running cloudspeech_demo.py errors out

[mikedougherty3]

Hello, I am trying to get this up and running as a christmas present for my daughter, but I am running into an issue. I was able to run cloudspeech_demo.py (or my own script) and then all of a sudden started getting the following error when I push the button. So I re-burned the image on the SD card, and set everything back up, but I am still getting this error. I have looked around but can't find anything useful. Also, assistant_library_demo.py works great, if that's any help. Thanks!

+1 my previously working cloudspeech.demo is no longer working. Traceback is similar to the above

Likely because of this: https://groups.google.com/forum/#!topic/cloud-speech-discuss/p8ZTlAVXyo0

I'll look into updating our code.

You should be able to git pull for a fix. If you have changes in a local branch, you can git pull --rebase origin voicekit.

Once we've released an updated image we'll mark this issue as fixed.

@mikedougherty3 & @sheridat, thank you for reporting this! Let me know if the fix works for you or not.

[sheridat]

@drigz Thank you for fixing it! Working fine.

[sheridat]

Just a thought - won't the people who have remained on the master branch have the same issue? Won't you be fixing that because the branch is deprecated?
BTW - I have put a post on the forum advising voicekit users that they need to pull the fix.

@drigz This definitely worked! I appreciate your responsiveness in getting it done! Now my daughter can listen to Bad Lip Reading Star Wars over and over just by asking for it.

Closing: the v1beta1 servers were brought back up, and the upgrade to the stable v1 API was released in the 2018-01-03 image.
