Cause

---

There is a custom script in a ui policy that is attempting to modify the DOM in some way. The DOM element the script is looking for could not be found.

Resolution

---

1) Identify the ui policy causing the issue by using System Diagnostics > Debug UI Policies and observing the browser console log

2) Navigate to the affected policy and either disable it or adjust the script to ensure the element is valid before attempting to modify it
