I have a spec which is giving the error:
java.lang.ClassCastException: clojure.lang.PersistentList cannot be cast to clojure.lang.Named
when attempting to load the swagger UI for a compojure-api app.
The failing spec appears to be one that uses conditional keys in a :req parameter of a clojure.spec/keys declaration.

Environment:

  • [org.clojure/clojure "1.9.0-alpha17"]
  • [metosin//compojure-api "2.0.0-alpha7"]
  • [metosin/spec-tools "0.4.0-SNAPSHOT"]

Problem was that the or and and were not parsed correctly under s/keys required keys. Should be fixed now, could you verify with [metosin/spec-tools "spec-tools-0.4.0-20171007.191128-3"].
