Deleted files not working after upgrade to Nextcloud 15

Can't access files in trash bin after upgrade to NC 15.

TypeError: Argument 2 passed to OCA\Files_Trashbin\Trash\TrashItem::__construct() must be of the type string, null given, called in /var/www/nextcloud/apps/files_trashbin/lib/Trash/LegacyTrashBackend.php on line 62

I have this error too, and I too can't access my Trashcan. I get a circle of death when I try to access the deleted files, and the log entry is repeated.

TypeError: Argument 2 passed to OCA\Files_Trashbin\Trash\TrashItem::__construct() must be of the type string, null given, called in /var/www/html/apps/files_trashbin/lib/Trash/LegacyTrashBackend.php on line 62

Nextcloud 15.0.0
Ubuntu 16.04 (running in an LXC container)
PHP 7.2

I was unable to fix this by restarts / re-logging in etc., so I deleted the account and re-created it. That works again. Not a great solution, but it's working again SO FAR.

UPDATED: Same error re-surfaced, so it's looking to be quite a chronic problem. Deleting accounts and re-opening is not much fun, so I am stuck with this until a fix is issued.

This seems to be related with #13160 and happens here, too.

As a workarround you can delete the trashbin with the occ command.
For Ubuntu und other Debian based systems that should be:
sudo -u www-data php occ trashbin:cleanup --all-users

If you don't want to loose your files in the trashbin you can backup, the data folder, or more specific you only have to backup the files_trashbin folder, in each user directory in the data folder.

Very useful to know that - will save me deleting accounts and getting them re-created - thanks Freshdouble.

Thanks, works as a workaround...

New Nextcloud 15, same thing.

I have the same Problem when I deleted or moved files in a synchronized folder. Doing this directly in the web ui works fine.

Same problem here with Nextcloud 15.0.2 with the error :
TypeError: Return value of OCA\Files_Trashbin\Sabre\AbstractTrash::getSize() must be of the type integer, float returned
Thanks a lot for the workaround.

This helped me on my Nextcloud 15.0.2

iocage console nextcloud

occ trashbin:cleanup --all-users
