VidLooper has no attribute?

[NoobyNick2]

I am relatively new to the Raspberry Pi world, and am struggling with programming. I am using a Raspberry Pi Zero W to build a video kiosk in a small museum. I am using four buttons for the project, hooked up to a 32" TV. I am using Alex Lubbock's guide to program it (linked at the bottom). I was just testing the new command with some sample code when this came up- AttributeError: 'VidLooper' object has no attribute 'debug' I will put a picture of the full error also. Please let me know if you find a solution. It would be greatly appreciated. Guide - https://www.vanderbilt.edu/the-wondry/software-for-a-button-driven-raspberry-pi-video-player/ Full Error -
