Problems creating geometry through mesh

Hello, I’m trying to create a geometry using a mesh in Dynamo, but when I insert the mesh, Revit presents this problem that can be seen in the image, the size of the mesh is 19.8 mb, does anyone know the reason for this error?
Rotina completo com mesh.dyn (25.7 KB)

No image attached, so we can’t react to your problem.

thanks for letting me know
