Uncaught TypeError: Cannot read property 'appendChild' of null

Product: TIBCO Spotfire®

Problem:

Uncaught TypeError: Cannot read property 'appendChild' of null


Solution:

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.
