Mininet connection problem to ONOS controller

When I execute the following command

sudo mn --controller remote,ip=127.0.0.1 --topo=single,4

ONOS shows the following Error

Error while processing message from [127.0.0.1:54080 DPID[00:00:00:00:00:00:00:01]]state WAIT_METER_FEATURES_REPLY io.netty.handler.codec.DecoderExpeption: org.projectfloodlight.openflow.exeptions.OFParseError: Wrong length: Expected=40(40), got=32

Kindly Help, How to resolve....?

This is a problem, most likely, related to the OpenFlow version. As @ikerfah said, try to define OpenFlow 1.3 in the mininet command, like:

$ sudo mn --controller=remote,ip=127.0.0.1,port=6653 --switch=ovs,protocols=OpenFlow13 --topo=tree,depth=1,fanout=2
