Hyperledger Fabric Upgrading Chaincode after modification

Question

I am suppose to upgrade the chaincode

I have tried to execute the peer chaincode upgrade within the docker peer node:

peer chaincode upgrade -n tuna-app -p github.com/tuna-app

but end up with the error

 Error getting (testchainid) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [testchainid]: [Failed to get policy manager for channel [testchainid]])

Any ideas?

Answer 1

You need to specify the channel name for which you'd like to upgrade the chaincode, specify args and new version and specify the ordering service endpoints so peer cli will be able to submit the upgrade transaction:

peer chaincode upgrade -n tuna-app -v 2.0 \
               -c '{"Args":[""]}' \
               -p github.com/tuna-app -C mychannel \
               -o orderer:7051
