Could not boot metadata: Call to undefined method

[farhills]

Since upgrading to NC 28, my logs are getting hammered with the following issue:

and

I'm not convinced this is your issue, but the metadata app is common to all the errors, so I'm starting here. Available to help gather more info to troubleshoot further.

Environment: Docker (LSIO Image) 28.0.0 with MariaDB, hosted on Unraid.

Yes, can be a compatibility issue because of nextcloud/server#39595

Same here:
[no app in context] Fatal: Could not boot metadata: Call to undefined method OC\Server::getEventDispatcher()
GET /apps/logreader/api/poll?lastReqId=yCKaszSsBIIkgVZXswiD
von 172.20.0.1 von Thomas um 08.02.2024, 18:22:48

Metadata does not show up in Nextcloud 28.0.2

@tjakober this is a compatibility issue (see #105), and a possible solution is to disable the app until the updated version is released.
I'm closing this in favour of the earlier issue.
