the flow starts when i first enter yourapp.com/helloworld (a non-existing page)

  1. my 404 page is loaded immediately
  2. it then properly routes to yourapp.com/existingpage/helloworld but i briefly see the 404 page.

Also, i notice when i an routed to 404 page, it does not seem get the data path from page url. it will not display anything and be blank.
