Custom React Component Error

Hi All, I'm trying to get the provided ColorSelector form component working in XbyK Color Selector Documentation I was able to get everything set up. I can add the color selector as the Form component in a text field:

but when I add an instance of that content type I get the following:

With a console error that points to this react error: https://react.dev/errors/306?invariant=306&args%5B%5D=undefined&args%5B%5D=

Element type is invalid. Received a promise that resolves to: undefined.

Haven't worked with React much and followed the Xperience by Kentico documentation to get to this point. Any help in pointing me in the right direction is appreciated.
