Spotfire Web Player: Uncaught TypeError: Cannot read property 'appendChild' of null

Uncaught TypeError: Cannot read property 'appendChild' of null in Spotfire Web Player.

Details:

If the API developer places their JS-API calls to spotfire.webPlayer.createApplication() above the <body>, the API will fail. The console will log:

 Uncaught TypeError: Cannot read property 'appendChild' of null     at loadProxy (loader.js:55)     at Object.spotfire.webPlayer.createApplication (loader.js:36)     at index.html:18 loadProxy @ loader.js:55 spotfire.webPlayer.createApplication @ loader.js:36 (anonymous) @ index.html:18

Ensure that the JS-API calls to spotfire.webPlayer.createApplication() are written below the <body> tag as shown below.
