@JamesLee66
Sorry but it looks like your are facing one of the major problems of Rhino - mozilla/rhino#835.
At the moment there is no solution for that. I have some plans to overcome this but these are only plans so far.

Your options are

• disable js support - but i fear the page will no longer work for you
• ignore js errors (https://www.htmlunit.org/javascript-howto.html#Handling_of_JavaScript_errors), in some cases this works
• try to patch the js code on the fly by delivering a patched version of the js stuff (https://www.htmlunit.org/faq.html#HowToModifyRequestOrResponse)
• or ask your boss to pay me for implementing the support ;-)
