使用超级账本结构 2.0 提交链代码调用/查询时出错

Question

I have successfully committed the chaincode with command:

./peer lifecycle chaincode commit -o orderer.example.org:7050 --channelID mychannel --name emp_chaincode --version v1 --sequence 1 --init-required --tls --cafile ./crypto-config/ordererOrganizations/example.org/orderers/orderer.example.org/msp/tlscacerts/tlsca.example.org-cert.pem

Now when I try to invoke/query a the chaincode, I get this error:

Error: endorsement failure during invoke. response: status:500 message:"error in simulation: failed to execute transaction f490a9e7bca41ad10f68306decae2fdd73e09a9d5f81da7c9ee5cdc3811b3f27: invalid invocation: chaincode 'emp_chaincode' has not been initialized for this version, must call as init first"

and in chaincode container logs, it shows:

+ CHAINCODE_DIR=/usr/local/src

+ cd /usr/local/src

+ npm start -- --peer.address peer0.org1.example.org:7052


> employee@1.0.0 start /usr/local/src

> node emp_chaincode.js "--peer.address" "peer0.org1.example.org:7052"

Please let me know how can I fix it.

UPDATE:

After R Thatcher suggested flag addition, error I get now is:

Error: endorsement failure during invoke. response: status:500 message:"error in simulation: failed to execute transaction 038b5c303dfdd98db2c2fc0d2eac6146d7221691cbbed7a78227f5a76a31a240: could not launch chaincode emp_chaincodev1:5bcbed31afc58894912eb4c66d63adcec7eab029e2b911887412b119ef5cf319: chaincode registration failed: container exited with 0"

Answer 1

Right at the end of your error you have must call as init first .

I would think that you have used the peer chaincode lifecycle approveformyorg command with the flag --init-required . This means that the first invoke of the new chaincode must use the --isInit flag eg peer chaincode invoke -C tradechannel -n trade --isInit ... . After this first "special" invoke, other invokes and querys will be fine.
