Unable to push flows to OVS via RESTCONF

Since the new Datastore was made default unable to push flows to OVS.

Start mininet
sudo mn --controller=remote,ip=192.168.68.1 --topo tree,2 --switch ovsk,protocols=OpenFlow13

Push flow via RESTConf. http://127.0.0.1:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/2/flow/124
