Google Assistant on Raspberry Pi 3 - Running sample code - error Peer certificate cannot be authenticated with given CA certificates

Question

Using a Raspberry Pi with Raspbian GNU/Linux 9, on a Marty Robot, having installed the Google Assistant SDK as described on the official page

https://developers.google.com/assistant/sdk/guides/library/python/

Trying to execute the last step:

https://developers.google.com/assistant/sdk/guides/library/python/embed/run-sample

I expect it to work, simply to work.

But I've got the following Error:

(env) pi@martina:~ $ googlesamples-assistant-hotword --project_id "martinaaiy" --device_model_id "Martina"
device_model_id: Martina
device_id: 8375BDBA056A04CCB8EBDAF685DC07B5

Any help will be welcome.

Answer 1

After talking with a few other engineers, this error is being logged due to some legacy features that are being deprecated. It should not impact you from actually running the sample and the error will be removed in an upcoming SDK release.
