A project I work on has recently started to err out when calling cider-jack-in-cljs . The error in question looks like this:

{:type :js-eval-exception,
    :error
    {:status :exception,
     :value "Eval timed out!",
     :stacktrace "No stacktrace available."},
    :form (set! cljs.core/*print-namespace-maps* true),
    :js "(cljs.core._STAR_print_namespace_maps_STAR_ = true)"}
