I'm trying to integrate a webrtc stream to Google Assistant streaming on NestHub. When we send google an offer SDP, it doesn't hit our signaling url
https://developers.home.google.com/cloud-to-cloud/traits/camerastream
When sending a cameraStreamOffer SDP back as a response to Google for the EXECUTE response, it doesn't send any requests to the cameraStreamSignalingUrl endpoint. When we don't send an SDP back in the response, Google is able to send an offer SDP to the cameraStreamSignalingUrl endpoint, so it is able to hit the endpoint. There appears to be an issue with the SDP that we send to Google
This is the SDP that we are sending to Google
