I have setup the hyper-ledger fabric network with 2 organisation, and have install the fabcar chain-code with version v1.1 on peer and i am keeping the storage of blockchain.
Next i added more methods on fabcar, Trying to upgrade the exist fabcar to v1.2, but i am facing the error.
Error: could not assemble transaction, err proposal response was not successful, error code 500, msg cannot get package for chaincode (fabcar:1.2)
I am using the below command to upgrade the chaincode
peer chaincode upgrade -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n fabcar -v 1.2 -c '{"Args":[""]}' -P "OR('Org1MSP.peer','Org2MSP.peer')"
Error: could not assemble transaction, err proposal response was not successful, error code 500, msg cannot get package for chaincode (fabcar:1.2)
Means your upgraded chaincode was not installed on peers.
Check Your chanincode installed on peers or not?
peer chaincode list --installed
In the output, You saw the only previous installed chaincode. So you have to first package a chaincode and then upgrade a chaincode.
peer chaincode package ccpack.out -n fabcar -p github.com/hyperledger/fabric/examples/chaincode/go/fabcar -v 1.2 -s -S
peer chaincode signpackage example
peer chaincode signpackage ccwith1sig.pak ccwith2sig.pak
Upgrade chaincode
peer chaincode upgrade -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n fabcar -v 1.2 -c '{"Args":[""]}' -P "OR('Org1MSP.peer','Org2MSP.peer')"
I recommend this link to upgrade your fabric chaincode.
Note: replace chaincode path with your chaincode path.
Hope it will help you :)
