Won't this have an impact on AWX? I don't think we use the --json flag (we could), but I don't see how this is conditional on requesting JSON.

@AlanCoding

there are 2 parts to receptorctl, ReceptorSocket which is the class that handles all socket IO, and the click library which is just the human-friendly command library which uses ReceptorSocket.

AWX interacts with receptor via the ReceptorSocket only, not via the click library.

in receptor.py

from receptorctl.socket_interface import ReceptorControl

This fix just affects click library usage, so it shouldn't have any impact on awx.
