I am trying to query the chaincode example 02 that I have deployed in the local blockchain installation.

I have tried both inside and outside vagrant setup as described by hyperledger-fabric docs.

The chaincode go file build successfully and the deployed seems to word.

The invoke function generates the transaction hash, however as soon as I query the state of variable A using the chaincode hash id, it always indicates an error indicating that the chaincode is not deployed successfully.
