Preloader wont ignore websocket - pace js

Question

I added preloader to my website which runs with ruby on rails, it seems it works perfectly, but because of pusher websockets, preloader does not end, it waits all the time, i tried this at my footer,

<script>
window.paceOptions = {
    ajax: {
      trackWebSockets: false,
      ignoreURLs: [/pusher/, /heap/]
    }
  }
</script>

but it did not work. how can I solve this problem?

Answer 1

I tried this one, it worked. :)

Pace.options.ajax.trackWebSockets = false;
