Async request Exception - ¨Publish¨ object has no attribute ´async´

[Nikolay Avramov]

Hi,

I have completed the setup of the module with audio and assistant test working correctly.

Once I run the assistant.py script I am getting an error which prevents the module from working:

pi@raspberrypi:~/MagicMirror/modules/MMM-GoogleAssistant/pi $ sudo /home/pi/env/bin/python3 -u assistant.py
pubnub subscription completed
Async request Exception. 'Publish' object has no attribute 'async'
Exception in subscribe loop: 'Publish' object has no attribute 'async'

After this error the hotword gets detected, but then another errors are logged and nothing happens:

Playing WAVE 'start.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
Traceback (most recent call last):
  File "assistant.py", line 137, in <module>
    main()
  File "assistant.py", line 134, in main
    init_googleAssistant()
  File "assistant.py", line 130, in init_googleAssistant
    process_event(event)
  File "assistant.py", line 100, in process_event
    pubnub.publish().channel("magicmirror").message("ON_CONVERSATION_TURN_STARTED").async(my_publish_callback)
AttributeError: 'Publish' object has no attribute 'async'

Is anyone getting this error, or got a working solution?

Thanks a lot!

yes i am getting the same error

(env) pi@MagicMirror:~/MagicMirror/modules/MMM-GoogleAssistant/pi $ python assistant.py

As the error is from the publish method, it could most probably be because async has been changed to pn_async

refer this:
https://www.pubnub.com/docs/python/changelog#v4-1-1

[Gaurav Singh]

hey @mayankkumar15 yes the method name change is the problem. Do you want to raise a PR with this fix?

Copy that, getting the same error on here. start.wav will play, but no response from Google received

[cphamlet]

To anybody else receiving this error, do:

pip uninstall pubnub 
pip install==4.0.13 

[ypearson]

pip uninstall pubnub
pip install pubnub==4.0.13

Tried that, and went into MagicMmirror, said "hey google" and without any animation got the response "something went wrong try again in a few moments". Exited MM, tried the google sample and recieved the audio 47 fault again. Restarted the Pi, then the google sample worked but nothing out of MM so i ran assistant.py and got an error about pn_async, so I edited the assistant.py and removed the 'pn_' from the four async strings and ran assitant.py again and recieved "hello from pubhub" tested google sample and that was working, test MM and still no response from GA.

I greatly appreciate you taking the time to help with this.

while True:
sensor_value = {'voltage':random.uniform(-5, 5)}
print(sensor_value)
envelope = pubnub.publish().channel('channel0').message(sensor_value).sync()
print("publish timetoken: %d" % envelope.result.timetoken)
time.sleep(5)

[maikinmoves]

Am i suppose to add that code to assistant.py

[ypearson]

I had trouble with async(), so I just used the sync() method instead.

If you want to publish msgs you can try the about code. The setup code isn't shown.

[Nikolay Avramov]

The renaming of the async() method to pn_async() worked for me.

Thanks a lot.
