Upload in sharink link not possible anymore

Hello Nextcloud Community,

I hope this message finds you well. I am currently facing an issue with Nextcloud and would appreciate your assistance in resolving it. When attempting to upload a file using a shared link. Everything was ok , until I move to the 28.0.0 version,

as a user I got : Could not upload “quizz_1.png”

Nextcloud version (eg, 20.0.5): 28.0.0
Operating system and version (eg, Ubuntu 20.04): dockerised nextcloud:28.0.0 on ubuntu focal

The issue you are facing:

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

Steps to replicate it:

  1. go to Things
  2. try to put a file using drag and drop
