I'm using fabric tools provided for composer to deploy fabric network as it deploys 1 peer, 1 orderer, 1 couchdb, & 1 fabric-ca. I am able to install chain code on peer but instantiation fails with following error. I am using command on fabric-peer.

`peer chaincode instantiate -o orderer.example.com:7050 -C composerchannel -n test -l node -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}'`

And if I check the logs of orderer I get:
