Surface Morph open/closed Brep


I am currently working on a voronoi structure morphed onto a surface. After generating the voronoi in a 2D-dimension, the Brep is closed. But after morphing the strucutre on a curved surface, the algorithm returns an open Brep. Since the purpose of my work is to 3D-print the object, I have to figure out a way how to fix this issue.

Does anybody has an idea or knows where my mistake came from?

I attached the algorithm and inserted simplified but representative data.

Here ya go!
I think the issue comes from the surface seam line.
