Executing Python with Web Remote Control

Hi all!

I’m attempting to create a remote instance of Unreal that will be able to able to use HighResScreenshot (or Pythons equivalent command) or render sequences. I’ve tried running a Python server directly in Unreal and while seems to be able to run the server it crashes the the rest of Unreal (even if I use multithreading to put the server in it’s own thread). Now I’m trying to achieve this through the Web Remote Control plugin. I can get this running no problem but can’t wrap my head around the the documentation for executing Python.

It says:

And then in the API HTTP reference it says:

Anyone smarter than me able to help me parse this or provide guidance on how they’d tackle setting up a system that can take remote renders on an EC2 instance.
