We use team folders. After the update from 31.0.12 to 31.0.14 most of the groupfolders are vaished at the desktop client and on the web site. I investigated a little bit and saw that the files at nextcloud data/__groupfolders exists. What I saw is that the in db table oc_group_folders the column ‘root_id’ is NULL for all vanished folders and not NULL for the visible folders.
Is this the reason and how can this work in the 31.0.12 and not work in th 31.0.14 and what can I do?
Hey, there’s a discussion somewhere in the groupfolder issues about exactly that: Issues · nextcloud/groupfolders · GitHub. IIRC there was something about a migration that missed filling in the root_id correctly.
Your link is not really the same issue. The Teams app do not crash and the inconsistency is not in the oc_file_cache but in the oc_group_folders. But may be it is the same root reason.
Groupfolders == Team folders. It is the same app, it was just renamed at some point.
