[solved] Greenlight preuploaded presentations not working

[manfred-w]

If a presentation is uploaded via the greenlight it is not visible when starting the conference.

Steps to reproduce:

1. Inside greenlight click the room menu => add presentation => upload a pdf
2. start the conference
3. the presentation is missing
4. during the conference i am able to upload a pdf and use it as presentation

Thanks

Hm, works on my setup (v2.2.31), but depending on the presentation it takes a while for it to be converted before it is actually displayed. Does it show any conversion progress in the "add presentation" menu during the conference?

Re-tested it today with current 2.2.x setup - does still not work.

There seems to be a call

That redirects to

But that results in a 404 error.

Found the problem and posted a pull-request (bigbluebutton#116) for the 2.3 bbb/docker version.

add to mod/nginx/bbb/greenlight.nginx the following lines and restart the container

location /rails/active_storage {
  return 301 /b$request_uri;
}
