Hi I'm trying out the word-count example from the jackdaw github page and I started the REPL did a successful (reset) but I get this error when trying to execute (topic-metadata) in the REPL. Can someone give me some pointers?

user=> (publish (:input (topic-metadata)) nil "all streams lead to kafka")
Execution error (ClassCastException) at user/eval6136 (REPL:1).
jackdaw.repl.FakeTopicMetadata cannot be cast to clojure.lang.IFn

from the error message I'd try changing (:input (topic-metadata)) to (:input topic-metadata)
