Description

Steps to reproduce
  1. Create a new group and set it as default for new accounts in registration app settings
  2. Share any file with this group
  3. Create an account using the registration interface --> Internal server error
    In nextcloud log:
[index] Erreur: The root directory of the user's files is missing
	GET /apps/files/
	de <ip> par <username> à 7 mai 2026, 16:35:22
Additional information:
  • There is actually a directory for "username" in nextcloud_data/
  • Trying again to log in to the newly created account still leads to the internal server error, with the same entry in nextcloud logs.
  • If I try to "impersonate" the newly created account from the admin panel, then it seems to be fixed. Afterwards I can normally login to the account, without any error.
  • I think the problem occured since an update to Nextcloud 33.0.3.
  • There is no error if I create an account from the admin panel
  • There is no error if I stop sharing files to the default group for new accounts (or if I don't select a default group)
Server configuration

Web server: Apache
Database: Mariadb
PHP version: 8.4
Nextcloud version: 33.0.3.2
Registration app version: 2.9.0
Not sure if it matters: the default app for my instance is "Files" (not dashboard)

Research direction

Reproduce the failure through the registration interface with a default group that has a shared file, then inspect the Nextcloud log entry about the missing user files root. Trace the registration account-creation path and its handling of default-group shares; done means newly registered accounts can open Files without the internal server error.
