Creating an 3D shape with solver-mistake occure

Hi, I am trying to create a 3D shape based on a blob-shaped surfacе. The condition is that I need 7 anchor points; the outline of the form and the line going across it must have their own stiffness. Nevertheless, solver found some mistakes but I can figure out where.
