Cannot invoke method reset() on null object and Cannot get property 'JobBOVOList' on null object

Summary:

I have created a Worker Assignment Object Validation rule to display Error Message when manager attempts to change employees job code and it contains a change in FLSA status.

When I test the rule I am receiving two errors related to null object. Any thoughts on why I am getting these errors?
