Error exception on change constraint

I’ve experienced an issue opening a previously saved MPP by Aspose. In this scenario, I only open the MPP File and set the constraint date to this day. I’ve attached the source and MPP file.

public void Case021()

{

using (var stream = File.Open(@"F:\Iniciativa Folgas Planejadas01-02-201715-59.mpp", FileMode.Open))

{

var project = new Project(stream);

project.RootTask.Children.First().Set(Tsk.ConstraintType, ConstraintType.StartNoEarlierThan);

project.RootTask.Children.First().Set(Tsk.ConstraintDate, DateTime.Now);

}

}

The code above throw the exception:

Object reference not set to an instance of an object.
