same issue here with NC 29.0.1

Hello,
@RolKl the logs are similar? We tried to reproduce without success, both on new install or by updating the app through the appstore.

Sorry, my knowledge is limited. I installed NC at a web host and not on my own server. So I have limited access. Where can I find the log file I need?

You schould have access to the logs in the adminsettings of your nextcloud...

Should I give you any other information (installed apps etc.)?

Hello, I've the same issue on Nextcloud 28.0.10 when I update or install BBB 2.7.3 (2.7.2 was working perfectly).
This morning, installing BBB don't crash my instance, but, I can't activate this app.

Error log :

A fix has been made by @smarinier . Until a new release is made (I can't give you a ETA atm, but should happen sooner than later), you can probably patch yourself as it's not a big change: arawa@834e2a7

This piece of code hasn't moved in ages, I'm a bit confused on why it happens now. Did you all upgrade to 2.7.2 before without any issues?
Out of curiosity, any big changes on your Nextcloud between 2.7.2 and 2.7.3? I wonder what could have created those nameless groups. My guess it that it's made by a third-party app because we couldn't reproduce the bug on our side with a relatively stock NC.

Best regards,

EDIT: Reopening the issue until the release is done

The change is very small, can be tried if you can modify the files:

@ThibautPlg I updated nextcloud from 27 to 28 before upgrading to 2.7.3.
3rd party apps: Onlyoffice, Ldap user and groups backend, Discourse SSO. And we use a lot of group folders. Oh, and the instance runs on a univention system in a container. I can't think of any more unusual features...

[RolKl]

Thank you for the solution.
I have made the changes as indicated, but cannot force a restart as I am with a web host.
I receive the message: "this app cannot be activated because it makes the server unavailable".
Does anyone have an idea?

[RolKl]

My solution:
Delete the app bbb
update nextcloud to 30.0.2
reinstall bbb

Runs great

Thanks for this great piece of software!

P.S. (Can you also improve the plug-in to moddle, they could learn a lot from here ;-) )
