Q:

Missing required parameter in clojure.java.jdbc

I've been tearing my hair out over an issue with db-specs in clojure.java.jdbc. I'm wondering if some behavior has changed recently, because something almost identical to this worked up until very recently. 
My db-spec looks like this:
(defn prod []
  "Yes, I've verified all of the loaded properties are accurate for the connection"
  { :classname (get-property "acedia.bbts")
  :subprotocol (get-property "acedia.bbts.subprotocol")
  :subname (str "@" (get-property "acedia.bbts.dev.host") ":" (get-property "acedia.bbts.dev.port") ":" (get-property "acedia.bbts.dev.sid"))
  :user (get-property "acedia.bbts.dev.user")
  :password (get-property "acedia.bbts.dev.password")})

And then at the REPL:
user => (prod)
{:classname "oracle.jdbc.driver.OracleDriver", :subprotocol "oracle", :subname "@hostname:1521:bbts", :user "user", :password "pass"}

user=> (with-connection bbts-dev (with-query-results rs ["select * from customer where rownum < 10"] (dorun (map #(println (:firstname %)) rs))))

user => (use 'clojure.stacktrace)
nil
user => (e)
java.lang.IllegalArgumentException: db-spec acedia.db.bbts$prod@4d24bd93 is missing a required parameter

I have no idea what the NO_SOURCE_FILE is in reference to, either. I've verified that the oracle driver is accessible, loaded, etc., as well. What parameter could I be missing in the db-spec?
Note: I have the same problem with MS SQL Server.

A:

The issue is that prod is a function, so either change prod to be (def prod {all props here}) or call the prod function when needed: (with-connection (prod) (with-query-results
