AIY authorization Error running voice/assistant_grpc_demo.py

Question

Have setup the RPi Zero Wireless, with AIY kit and projects, and have setup Voice Kit Google Project and enabled Google assistant, and setup user credentials(OAuth)

Running the voice/assistant_grpc_demo.py demo presents the https: link with brings up the google log in screen. Clicking the the correct user account, results in an Authorization Error Page: Error 403: access_denied.

The client id is correct in the 'Request Details' so it appears the demo python code is finding the credentials json file correctly.

So now I am stuck trying to figure out why I am getting 'access denied' error?

Answer 1

Ok, so the AIY setup instructions fail to mention about adding Test Users to the OAuth Consent screen.

So just added myself as a Test User, and the HTTPS link now worked to Allow for access permissions.

To add a Test User, go to the google cloud console ( https://console.cloud.google.com/ ) select your Voice Kit project, from the menu select APIS & Services, OAuth consent screen, Test users

from there you use the + ADD USERS button to add a test user.
