Remove SW2 property "description" to a node - not working for both OF13 and OF10 mininet

Hello,

While testing NSF with new plugin, I am able to create description to a node i.e., PUT http://127.0.0.1:8080/controller/nb/v2/switchmanager/default/node/MD_SAL/openflow:2/property/description/Switch2 and verified too at http://127.0.0.1:8080/controller/nb/v2/switchmanager/default/nodes

When I try to remove the description i.e DELETE http://10.125.136.52:8080/controller/nb/v2/switchmanager/default/node/OF/00:00:00:00:00:00:00:02/property/description, I am getting 500 internal error.

Please let me know if you do get the same response. If that is so, please fix the same accordingly.

This test case is working with old plugin.

Thanks,
Madhusudhan
