Expected:
Tried accessing a WebRTC stream via the smartdevicemanagement API.
Actual:
Instead of getting a WebRTC stream, I got a HTTP 500 Internal Server Error response.
Description:
Using my HomeAssistant integration, which has been working just fine for my old Nest Camera (pre-Google) camera via Google Home as well as my new Google Nest Thermostat for months, I just authorized access to the integration and my new Nest Outdoor Camera (battery, with attached power cable) and the camera appeared in HomeAssistant.
However, upon trying to view the camera I get the following errors in the debug log:
