I wanted to try out Caldera's dynamically compiled payloads so I read the docs and set up my abilities but nothing was happening. Eventually I clued in to the plugin not being actually enabled but when I tried to enable it I got the following error when starting up the server:
2023-07-24 17:39:18 - ERROR (c_plugin.py:70 enable) Error enabling plugin=builder, request() got an unexpected keyword argument 'chunked'

So I started putting debug strings in the plugin's hook.py, build_svc.py and c_plugin.py and eventually I figured out it had something to do with Docker. I did some digging and found this: docker/docker-py#3113

I do not have docker-py installed but once I set requests to 2.29.0 (pip install requests==2.29.0) the docker images started downloading. When you make an ability then check out the yml file, the format is a little different than the example format on the builder plugin's github page. This is what worked for me:

And this version, which should compile HelloWorld.cs, failed for some reason.

It looks like it created the exe but didn't xfer it to the target system? Idk, will play with it and see if I can get it working.
