I don't think you can have the generator code within the spline definition.
I did something like that & I had to declare ;
    array points[num_points] { my_point, ,,(fill rest of array with
randomgenerator),, }

Then build the spline from the array;
    spline {
        natural_spline
         0, points[0], points[1], ,,(on out to num_points...)
    }
