Uncaught TypeError on initial load of web app

[GeorgeHilton__GISP]

I have a Javascript API 3.x application I"m working on.  I am receiving an error when trying to load the application in a browser stating : 'Uncaught TypeError:  Cannot read property 'removeChild' of undefind'   This error appears when initially trying to load the web page.  If I refresh the page after receiving this error, the page is able to load successfully.  I've attached the full error message from DevTools to this question as a jpg.

The URL for the application is : https://qbygis.queensbury.net/webapp/default.html

Any help is greatly appreciated !!

Are you still facing this issue George? I did some testing with Chrome and Firefox, and I do not see an issue with loading the webmap.
