Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 23.0.0

PHP version (eg, 7.4): 8.0.14
The issue you are facing:
When I upload a big file (8G for this example), I get this message error : “Stream from assembly node shorter than expected, got 7140138 bytes, expected 10485760”
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Install nginx and configure it for large upload (tmp dir, tune php, tune timeout…)
- upload a big file to local storage : it works
- Change storage to object storage via config.php
- retry uploading the file : the message occurs
