Unable to run Vega-Lite visualization example through local server

I am learning Vega-Lite.

When I try to run a simple bar chart example. Browser console throws an error:

I am running this example

I am using webstorm IDE; It creates a local server through which I am serving webpage to browser. I have also tested with python http server as well. Results are same.

Error:

Failed to load resource: the server responded with a status of 404 ()
