Breakout Rooms - Saving / converting whiteboard doesn't work
Hi!
I just tried installing BBB via docker for my private server and realized that after creating a breakout room with the setting "Save whiteboard", going into the breakout room to write / draw something and closing the breakout room, the presentation apparentaly can't get saved / converted.
Inside the logs I get the following error:

Any ideas of what could be the issue?
For me, the conversion at all doesn't work. I fixed it by recreate the image with a modified process.js
So first question is, does the export on the "main room" works?
https://github.com/bigbluebutton/bigbluebutton/blob/v3.0.x-release/bbb-export-annotations/workers/process.js#L428 i removed the quotes there.
ps: the deprecation warning can be ignored at the moment. pps: the problem is the process.js doesn't catch any error from ghostscript
After seeing another issue, the presentation itself wouldn't be exported, i rebuild the image, on ubuntu base. i will create a pull requests the next days.
Which image you talking about benjamin? Is it the [bbb-export-annotations]?(https://github.com/bigbluebutton/docker/blob/bbb3.0/mod/bbb-export-annotations/Dockerfile)
Exactly

I don't understand the ubuntu base mean, i can't find that image in node docker hub, correct me if i'm wrong :D Here is bbb-export-annotations base "FROM node:22-bookworm-slim AS builder"
@ben-ba hey Benjamin can you take a little time to look at this? Really appreciate your help
Yes, I have a working image, i will deploy it during the day and push it here.

this is my updated, working Dockerfile, main differences,
- using ubuntu instead of node as base image (the node image using an debian base image)
- proxy support, if you don't need it, remove the http(s)_proxy vars / lines
notes:
- installing node, because no official node image based on ubuntu is available
- using ubuntu instead of debian, because the debian ghostscript return an uncatched error - by bbb
- should also work without the packages poppler-utils, imagemagick; see https://github.com/bigbluebutton/bigbluebutton/issues/19703#issuecomment-3138094933 , but atm untested
- 172.17.0.1 is the docker0 interface on your host machine
