HTTP POST: Exception thrown: 'System.InsufficientExecutionStackException'

[solaris-83]

I have cloned the repository, built a run the solution successfully. When I issue a POST request I get the following unhandled exception.
I can't figure out what's going on. I'm using VS 2017 and 2019.
Can anyone help me please? Thanks.

@solaris-83 please grab the newest release and test it. I fixed the POST and PUT actions.
