Unable to connect to Appian Portal in Community Edition

Certified Senior Developer

I am using my community edition instance to learn about portal and their configuration. I have created a basic interface with just a layout and some text fields as well as a portal object. I have configured the interface as a page and published the portal. When I go to the portal link I am getting an error. From what I can see I have everything required configured and I'm not calling any special plugin functions. I'm literally trying to get the most basic setup to facilitate learning.
