Enabling record: true on HomeKit video stream results in crash

[hazcod]

Hi, trying to get an Aqara G4 doorbell to work over HomeKit and recording. (timeline in Hassio>Homekit)
When adding record: true to my streams, it crashes with a nil reference.

Go2RTC Config:

streams:
  doorbell: homekit://xxxx:33151?device_id=94:41:B9:ED:BD:7B&device_public=ef8a5e.....
  record: true

api:
  listen: "127.0.0.1:1984" # localhost

rtsp:
  listen: "127.0.0.1:8554" # localhost

webrtc:
  listen: ":8555" # external TCP/UDP port

And logs:
