Spins forever: Reolink integration camera streams on Google Home via NabuCasa

My Reolink cameras are connected directly to the Reolink NVR, so that the recording streams don’t congest my LAN. Naturally this doesn’t allow Google Cloud to see the streams.

Instead, I’m using Home Assistant and the native Reolink integration to expose a few of my camera streams (via the NVR integration) - the fluent entities, to be specific - to the Google Assistant.

The cameras then show up as camera devices in the Google Home app as a camera device, as expected, which is great.

However, when I click on the camera, it spins forever. It seems the NabuCasa Google Home integration isn’t forwarding the stream to Google’s servers correctly for display in the Google Home app?

(Ideally I’d like to show it on one of my Google TVs or Google Home Hub displays)

Is there a bug here? It spins indefintely and the logs don’t show anything.
