Error to add nw_dst as a Match field while working with OpenFlow v1 in ryu

Question

I am using RYU controller with flowvisor. As flowvisor do not support any other version other than openflow v1. I am using openflow v1 in my project.

I have topology of 3 ovs switches and controller sits in one of server conataining ovs bridge. Other two ovs bridge in other servers connects to controller through public interface. But when run my ryu application, it connects to switches but not able to add rules with nw_src match . I am getting this error here:

hub: uncaught exception: Traceback (most recent call last):

My code is here:

Please help.
