I'm getting a pretty out of place error trying to fetch data from a swagger API

I'm basically turning some basic JSON into edn and trying to fetch that for which I get

ERROR compojure.api.exception - No implementation of method: :render of protocol: #'compojure.response/Renderable found for class: clojure.lang.PersistentVector java.lang.IllegalArgumentException: No implementation of method: :render of protocol: #'compojure.response/Renderable found for class: clojure.lang.PersistentVector

Think it might have anything to do with me trying to make the data go through this?

Never mind, I wasn't doing (ok (fn... ))
