I'm developing a simple hello world web app in Clojure. However, after I added the Schema library to my project, I started getting the error below when trying to build an uberjar using lein uberjar. Strangely, the app still passes the unit tests and runs without errors when started using lein dev.

Below is the source file where I use schema. For brevity, I've omitted the rest of my source files, but if anyone wants to see the rest, just ask.

I also looked for the 'missing-required-key' key in the Schema source code and made sure it is quoted properly, it definitely seems to be, since if I change it Schema's tests start failing.
What else is different about the compilation process when creating an uberjar compared to compiling normally? Is there anything else I can try?
