Re-building a Unreal Engine 4.26 plugin to 4.27

Question

Hello,

I am attempting to rebuild a plugin called Cinematic Camera Manager for 4.27. I follow the tutorial here:

https://www.youtube.com/watch?v=2HHJ6AYnwFw&t=306s

Using CMD I enter the following:

C:\Program Files\Epic Games\UE_4.27\UE_4.27\Engine\Build\BatchFiles>RunUAT.bat BuildPlugin -plugin="C:\Users\jeric\Documents\Unreal Projects\AdvancedARPG\Plugins\CinematicCameraManager\CinematicCameraManager.uplugin" -package="C:\Users\jeric\Documents\Unreal Projects\AdvancedARPG\Plugins\CinematicCameraManager\CinematicCameraManager427"

and when the build fails I get the following:

Running AutomationTool...

I am new to coding and using visual studios, but I am trying to learn as I go along and troubleshoot. I'm completely stumped. Can anyone help me figure this plugin out or let me know that it requires reworking on the creator's behalf? This plugin is a part of a more expensive pack and he doesn't seem interested in updating the standalone.
