Flow denial on uploading private files prevents NC Talk Folder access/creation #206

Open
@rkwillig

Description

Steps to reproduce

  1. Creating flow rule with following filters: "Tag - not tagged by - TAGNAME" && "User Group is not ADMIN"
  2. Installing nextcloud Talk App
  3. Create new user

Expected behaviour

User is able to login and is able to use Nextcloud Talk

Actual behaviour

On first login User is getting an internal server error, log shows that the flow rule denies creation of "Talk" folder in user directory.
pre-creating the folder "Talk" by skeleton directory ist working to create the folder and let's the user log in, but the user has no access on the "Talk" folder because of the flow restrictions.
I haven't found any way to exclude the folder from the rule, so the user can use NC Talk.

Users should not be able to upload files to their own NC (Home) folder, but they should be able to work in shared folders and should be able to use NC Talk.
