NPE while restconf flow update

odl: Lithium RC0

features: odl-openflowplugin-flow-services-ui (He design plugin)
or
features: odl-openflowplugin-flow-services-ui-li (Li design plugin)

i have run suites from integration git as
pybot -v CONTROLLER:10.25.2.9 -v MININET:127.0.0.1 -v MININET_USER:mininet -v USER_HOME:/home/mininet -v RESTCONFPORT:8181 tools/OF_Test/robot_suites/998_Independent_OF_Tests_ovs/020_Flow_Data_Tests.txt csit/suites/openflowplugin/Flows_OF13 csit/suites/openflowplugin/Flows_Stats_OF13 csit/suites/openflowplugin/Flows_Additional_TCs/Stat_Manager_extended

running just suite csit/suites/openflowplugin/Flows_Additional_TCs/Stat_Manager_extended does not replicate the case and test are passing

updating the flow in config datastore returns http status 400 with {"errors":{"error":[

{"error-type":"protocol","error-tag":"malformed-message","error-message":"Error parsing input: Content is not allowed in prolog."}

]}}
