Groupfolder not usable on NC4UCS

Hi,

we have installed NC16.04 on an Univention corporate Server with the groupfolder app 4.1.4.

Unfortunately the app is not working as expected. Steps to reproduce:

  1. installed the app
  2. created a group folder
  3. assigned a group to the Folder
  4. assigned special permissions to the folder
  5. logged in as a user of this Group
  6. created a file
  7. received the error message, that the file could not be created
  8. can see in the file in the Shell
  9. can not edit the file in nextcloud

This is the logging error Messages:

[PHP] Error: Undefined index: permissions at /var/www/html/apps/groupfolders/lib/Mount/MountProvider.php#141

Any ideas on this?
