Hi Snicker, I have the same error here with the UCC 2.2.7 and Agility pack 1.0.9!
According to documentation, UCC must be installed and demo folder also present in project. I have followed the preconisations, I supposed you did also... Then something goes wrong with one of those last packages
This was my fault. When you submit a package you have to verify which versions it works on, and it looks like I removed 2018.4 rather than verifying that version. I've reuploaded and it should be live shortly.
