A Null was specified as an argument in a method invocation but the method declaration did not specify AllowNull for the corresponding parameter. If there are good reasons to be passing a null object to the method, correct the method declaration to indicate AllowNull. Otherwise, correct the method invocation to pass an appropriate object.
Note: Specifying an object that will be null at evaluation time will only shift the problem from a compile-time error to an evaluation time error, since a null object passed as a non-AllowNull argument will result in request cancellation.
