Original file name not showing for deleted files on Nextcould 27

Nextcloud version (eg, 20.0.5): 27.0.1
Operating system and version (eg, Ubuntu 20.04): Debian 12
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.57
PHP version (eg, 7.4): PHP 8.2.7

The issue you are facing:
I’ve upgraded from Nextcloud 26.0.4 to 27.0.1, and noticed that after the upgrade the name of the deleted files, under the deleted files view, is not showing. Instead, a kind of an ID is shown.
image

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Delete a file, either on the web interface or in a synchonized folder (wait for the sync to complete)
  2. Open the Deleted files view
  3. Notice the file name of the deleted file is not the same as the original filename
