TypeError: Cannot read property 'isOnlyAudio' of null

Hello @tilmanmoser,
Thanks for this enhancement. I'm getting some errors and will appreciate your help resolving the issue. I've followed the guide exactly as documented, the only thing I changed was from --user 998:998 to --user=998:998 based on docker documentation. I've tried using both the manual option and bbb-record --rebuild, please see below the result in both cases.

1. When I run the command manually for an already published presentation, I get the error below

ubuntu@ip-xxx-xx-x-xxx:/opt/bbb-video-download$ sudo -u bigbluebutton docker-compose run --rm --user=998:998 app node index.js -i /var/bigbluebutton/published/presentation/f729564ec72824546f0eab6badd8e9398b4e56cf-1614810834891 -o /var/bigbluebutton/published/presentation/f729564ec72824546f0eab6badd8e9398b4e56cf-1614810834891/video.mp4

  format: 'mp4',
  docker: true
}

    at async run (/home/bigbluebutton/index.js:10:9)

2. When I rebuild an existing presentation, the video.mp4 file is not created.

root@ip-xxx-xx-x-xxx:/opt/bbb-video-download# bbb-record --rebuild f729564ec72824546f0eab6badd8e9398b4e56cf-1614810834891

Any suggestion on how to fix this, preferably the second option so that mp4 videos are published automatically.

Thanks for your help.

Hello @tilmanmoser
Looking for help with this. I'm still unable to use the script due to the error described above. Can you please advise.

Thank you!

[tilmanmoser]

To be honest, I have no clue, how this can happen at all. If the webcams object is null, the code should never reach the line, where it breaks:

in the function combinePresentationWithWebcams are two null checks before that line, that handle non existing webcams:
[...]
if (!presentation && !webcams)
[...]
if (presentation && !webcams)
[...]
if (presentation && webcams.isOnlyAudio)
[...]

Can you provide the presentation data in question to run some tests on it?
