usage of store_force_contact in wall/gran

I am trying to use store_force_contact in wall/gran and I am using a mesh as the wall. Here is the line I am using:
fix granwalls all wall/gran model hertz tangential history meah n_mesh 2 meashes mesh1 mesh2 store_force_contact yes

But when I add the above keyword store_force_contact yes, then I get the following error:

Error: Invalid fix style: "contactproperty/atom/wall" (../modify.cpp:820)

I also want to output the above force value as well in dump please help me resolve these issues.

Thank you.
