Camera entity_id configuration usage is broken since 1.3.2

[DeKaN]

I use WebRTC custom integration in Home Assistant with installed go2rtc as addon
My camera is Ezviz C1C

I used card with this configuration at Lovelace

type: custom:webrtc-camera
entity: camera.entity_id_here

After updating go2rtc to 1.3.2-1.5.0 version I see Server disconnected at card with error in log:

As workaround I have to switch to direct url providing

type: custom:webrtc-camera
url: 'rtsp://USER:PASS@IP:554/Streaming/Channels/101'

or rollback go2rtc to version 1.3.1

Do you have something in the go2rtc YAML?

[DeKaN]

No, I haven't

Similar #474

same camera, same setup, same problem.
could it be something specific?
