Error while copying

Nextcloud version : 20.0.0.9
Operating system and version: Raspbian GNU/Linux 10 (buster)
nginx version: nginx/1.14.2
PHP version: PHP 7.3.19
mariaDB: 15.1

The issue you are facing:

I wanted to upload a big file to my cloud (~5.2 GB), for doing so i used the web interface via drag and drop.
The upload worked fine and the message taht my data become processed appeared, too. After a while i just got the message: “Error while copying file to target location (copied bytes: -1, expected filesize: )”. Server side encyption is deactivated and shouldn’t be the problem at this point.

Is this the first time you’ve seen this error?: yes

Steps to replicate it:
0. Login in user account

  1. Go to files page
  2. upload a big file via drag and drop
  3. wait until upload finished and processing has started

My Nextcloud log under /var/log/nextcloud.log is empty :confused:
