@KillerDeath is correct. please check your action. it may have null — Sahil Manchanda, Aug 10 '17 at 12:36
@NO_name YOu know that if you put the exception in the edit summary we can't see it easilly right? — litelite, Aug 10 '17 at 12:37
Try if((UDID)!=null && action!=null&&action.equalsIgnoreCase("insert")), action is probably reading a null value or not initialised at all — Clement Osei Tano, Aug 10 '17 at 12:40

Statement:

action.equalsIgnoreCase("insert")

will throw a nullpointerexception if action == null because you cannot call equalsIgnoreCase method on an unassigned variable.
