Maximum request body size 1048576 exceeded, actual body size 1049648

[Th0rgal]

Long story short

I'm trying to uploads small files (less than 120MiB) to my server written with aiohttp but when they are a little too bigs it doesn't work.

Expected behaviour

The request should be handled.

Actual behaviour

The server returns:
Maximum request body size 1048576 exceeded, actual body size 1049648

Steps to reproduce

Clone my small server polymath: https://github.com/Th0rgal/Polymath/blob/master/server.py
Perform:
curl -F "pack=@./file.zip" -F "id=666599" -X POST http://localhost:8080/upload

Your environment

My server runs under nixos 19.09 (linux 5.4.6) and I get this error with any clients (windows, ubuntu, nixos, etc).

Is there a way to change this limit server-sidely?

[hh-h]

client_max_size – client’s maximum size in a request, in bytes. If a POST request exceeds this value, it raises an HTTPRequestEntityTooLarge exception.
