Deploy Hyperledger Fabric NodeJS Chaincode

NodeJS Chaincode Deploy and Test

start Docker
cd /fabric-samples/basic-network /basic network
Edit docker-compose.yml change line no 72 comment and 73 uncomment. //prod to devp network
Edit start.sh add ‘cli’ in 15 no. line (docker-compose -f docker-compose.yml up -d ca.example.com orderer.example.com peer0.org1.example.com couchdb cli)
./start.sh //run start script to up network
docker logs -f peer0.org1.example.com //log (1 terminal)
docker exec -it cli bash //peer (2 terminal)
cd /fabric-samples/chaincode/hyperledger/fabric/peer/nodefiles (3 terminal)
Add chaincode node file package.json and mycc.js
npm install
CORE_CHAINCODE_ID_NAME="mycc:v0" node --inspect mycc.js --peer.address grpc://0.0.0.0:7052 //configured chaincode (everything fine you will get ‘Successfully established communication with peer node. State transferred to "ready"’ )
Go to terminal 2
peer chaincode install -l node -n mycc -v v0 -p nodefiles(directory name where we have put chaincode files)
CORE_PEER_LOCALMSPID="Org1MSP"
peer chaincode instantiate -l node -n mycc -v v0 -C mychannel -c '{"args":["init","1","2"]}'
peer chaincode invoke -n mycc -C mychannel -c '{"Args":["get","1"]}'
peer chaincode invoke -n mycc -C mychannel -c '{"Args":["set","1","1"]}'
peer chaincode invoke -n mycc -C mychannel -c '{"Args":["get","1"]}'

On Running line 13 i am getting an error:

And one more thing, while running npm install i got permission denied error, which i fixed by giving nodefiles sudo ownership

Hi any solution for the above issue ???
