dfsNewTask1D returning error (-1009)

Hello,

I am trying to execute the data fitting example

Here is the code of dfdcubicspline_interp.c file,the line 163:

/***** Create Data Fitting task *****/

errcode = dfdNewTask1D( &task, nx, x, xhint, ny, y, yhint )

Can anybody explain why dfsNewTask1D returning -1009
