IOS XE GuestShell - Execute Script from Flash

Anyone out there willing to help me understand what I'm missing here? I'm attempting to execute a python script from flash. Guestshell is working but I'm unable to execute from flash. HTTP server is enabled and running and I can ping between XE and guestshell.
