Console Error with Mock Server and Module CDN

[1sd15]

Hey! First off I'd like to say that I love how the project has been presented and maintained. I hope to use it more soon!

I'm hitting a snag on my Codepen (https://codepen.io/1sd15/pen/zYgGYEZ) in which hitting the Mock Server gives me back Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'toString') originating from the statusKey method.

I believe that this could be due the Module CDN but it could also be a mistake I've overlooked. I'd love some assisstance if possible!
