Tools/Joystick now working properly

[vcs-vct]

I checked out the master branch of openpilot. My plan was to use a joystick to control a 2021 Kia Telluride. I calibrated and ran openpilot on public road. I used Comma 3X and everything on public road with openpilot was fine.

I followed exact procedures in README to run joystick with keyboard.

"The car must be off, and openpilot must be offroad before starting joystick_control.

Using a keyboard
SSH into your comma device and start joystick_control with the following command:

tools/joystick/joystick_control.py --keyboard
The available buttons and axes will print showing their key mappings. In general, the WASD keys control gas and brakes and steering torque in 5% increments."

Once I started the vehicle, I got the following error
