Meter Statistics not showing output/logs on OSGI prompt and through REST

Start controller (./run.sh -debug) and mininet (sudo mn --topo single,2 --controller remote,ip=192.168.56.103:6653 --switch ovsk,protocols=OpenFlow13)
osgi> setLogLevel DECONTROLLER-5
osgi> addMeter openflow:1
Push XML(attached) using REST and GET works fine
http://192.168.56.103:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/2/flow/172
osgi> meterConfigStats
null
osgi> meterStats
osgi>
Below rest returns "404 Not Found", "No data exists" error
