isaac.Joystick component stalls.

[_PROTOTYPE]

environment

Isaac SDK ver 2019.2

hardware

PlayStation 3 DualShock 
(/dev/input/js0)

issue

I created a simple codelet that gets the joystick status.

(isaac.Joystick) --JoystickStateProto--> (my_codelet)

However, JoystickStateProto is not sent from isaac.Joystick.
And, isaac.Joystick node is stalled on Isaac Sight.

my_codelet.app.json

        "my_codelet:codelet-pkg",
