As documented, you need to create the property with

mesh.add_property_map<A,B>(default)

See https://doc.cgal.org/latest/Surface_mesh/#title7 for an example.

Thank you for your response.

I am getting error even using (label,vd),
is this line correct?
Mesh::Property_map<vertex_descriptor, std::int> label;
It showing error when I am using int but when I tried string it does not
show error but I am getting below output.

terminate called after throwing an instance of 'CGAL::Assertion_exception'
what(): CGAL ERROR: assertion violation!
Expr: parray_ != NULL
File: /home/sghos003/CGAL-4.13.1/include/CGAL/Surface_mesh/Properties.h
Line: 518

I am not understanding what wrong I am doing. the label value should be an
int value, I tried to even use template. But nothing worked.
