Can't bake a loft with applied voronoi. Its simple but can't solve it

I am trying to apply a voronoi texture to this loft between two ovals, its weird because this is a very simple operation, its not difficult but I cant bake the final result. I will be posting the file if someone would like to help me. I been trying to bake this surface for over hours and can’t find the solution, probably something I didn’t notice.

It only says “invalid brep” but doesn’t says why.

I would be very grateful if someone could help me, i don’t think it’s that difficult but I cannot do it.

Between [Box] and [3d Voronoi] use [scale NU]
