Getting "cannot set property Error of undefined" when trying to run the .js output of a simple hello world clojurescript

I'm compiling:

(ns example.hello)
(js/console.log "Hello from ClojureScript!")

With this configuration:

(defproject lein-cljsbuild-example "1.2.3"
  :plugins [[lein-cljsbuild "0.2.9"]]
  :cljsbuild {
    :builds [{
        :source-path "src-cljs"
        :compiler {
          :output-to "war/javascripts/mainz.js"  ; default: main.js in current directory
          ;:optimizations :simple
          :target :nodejs
          ;:pretty-print true
          }}]})

Which outputs a file that is too big to put here, but gives the error:

goog.debug.Error = function(opt_msg) {
                 ^
TypeError: Cannot set property 'Error' of undefined
