OBB error

I created extracted the polydata (TIN) from a terrain I generated using a combination of vtkDelaunay2D() followed by vtkWarpScalar() and finally GetPolyDataOutput()

I then used the following lines:

obbTree = vtkOBBTree()

but after I run the last instruction I get the following error/warning,

Generic Warning: In D:\bld\vtk_1661287277002\work\Common\Core\vtkMath.cxx line 814
vtkMath::Jacobi: Error extracting eigenfunctions

any help with this?
