unsupportedRequest when playback video with Docker bbb-playback-proxy:jammy-300-alpine

[PatLemaire]

Context

• Docker installation of Scalelite (https://github.com/jfederico/scalelite-run) with v1.6.12.1
• BBB instances v3.0.15

Describe the bug
When using "SCALELITE_RECORDINGS_DOCKER_IMAGE=bigbluebutton/bbb-playback-proxy:jammy-300-alpine" then Video playbacks lead from Moodle to an error message "unsupportedRequest ".

Using URL from BBB instance, video plays well.

Notice that "/playback/" is missing from scalelite URL. Even if I forced it, it comes back to /video/

Note
When using "SCALELITE_RECORDINGS_DOCKER_IMAGE=bigbluebutton/bbb-playback-proxy:focal-260-amazonlinux", Video playbacks works from Moodle but I get another error: Cannot read properties of undefined (reading 'length') when using Drawings.

Have u tried 1.7?
I can't confirm this there.

[PatLemaire]

Thank you very much @lonesomewalker for looking into my problem. I feel less alone.
Unfortunately, upgrading to 1.7 (even 1.7.1) and switching to "jammy-300-alpine" doesn't change anything.
I can still modify the URL and play my video from the instance that hosted the conference, but my users can't do that every time.
It's as if the path is corrupted in the 300-alpine image. "/playback" is missing from the URL.

[lonesomewalker]

Do u use a DB? If so, have you updated/upgraded it?
docker exec -t scalelite-api bundle exec rake db:migrate

[lonesomewalker]

And if you want to speed up things:
post your docker-compose.yml and .env here without the secrets.
Github is not a helpdesk, but maybe it is an ugly bug 😏

[PatLemaire]

There is no indication to update the database during the latest version upgrades. This was indicated during the transition to Scalelite 1.1 but not afterwards (see #656 (comment)).
Can you tell me where you found such an indication?

Thanks again for your time and support!

I've found something!
If I add, in data/proxy/nginx/sites.template.scalelite-proxy these few lines:

...
    location /presentation/ {
        proxy_pass  http://docker-scalelite-recordings;
        include /etc/nginx/sites-common;
    }

+    location /video/ {
+        proxy_pass  http://docker-scalelite-recordings;
+        include /etc/nginx/sites-common;
+    }

    location /playback/ {
        proxy_pass  http://docker-scalelite-recordings;
        include /etc/nginx/sites-common;
    }
...

Then the video is playing!
Indeed, the video format is not a native export format. Strange that it has to be added manually?

But I don't understand why the version of 'bbb-playback-proxy' works in some cases and not in others.

Mmmmmh, now i also see an instance where this issue occurs.
Time for debugging 👍
