            create a channel through node js in hyperledger fabric 2.0
            Asked 2020-Nov-19 at 11:31

            the channel is supposed to be created with the peer channel create inside the container after generating the channel tx files with configtxgen. I wanted to know if it is possible to create the channel tx files and create the channel with the help of the node js server like previously in the fabric 1.4 we used to do with the help of the fabric-client.

            At the moment there isn't an API in the Node SDK (v2) to manage the chaincode lifecycle. You should be able to use the SDK to invoke lifecycle functions using the system '_lifecycle' chaincode. There are also third-party libraries built on the SDK which provides some lifecycle support, e.g https://github.com/davidkhala/fabric-common/tree/master/nodejs/admin

            Error when instantiating a node chaincode on a channel
            Asked 2020-Sep-09 at 08:57

            I'm trying to instantiate an already installed node chaincode on a channel, but it fails with error: failed to invoke chaincode name:"lscc" , error: container exited with 0

            What I did up to this point:

            1. Successfully started a network with 2 organizations with 2 peers for each organization and a raft consensus using ./byfn up -c some-channel -s couchdb -o etcdraft -l node script from Building your first network (v1.4) tutorial. The network already has one instantiated chaincode named mycc.
            2. Connected to the network from my script using Node.js SDK. I am able to successfully invoke read and write chaincode methods of the mycc chaincode from my script.
            3. Installed new chaincode on all 4 peers using each organization's admin identities. I am able to confirm that the chaincode is indeed installed by querying installed chaincodes on a peer. Also peer container logs also confirm that the chaincode is installed successfully.
            4. Tried to instantiate the installed chaincode and encountered the above-mentioned error.

            Here is how I'm trying to instantiate my chaincode:

            My suggestion is that you have to use two different channels for two different chaincodes. You can install as much chaincode as you want in every peer but the problems will begin when you try to instantiate chaincode as this process is directly involved with network and channel. Though they change the instantiate process from version >= 2.

            For the records:

            For running a business, some organizations have to come into a consensus and so they have to create a channel where only permissioned organizational properties have access.

            Here within a channel every valid organizational peer hold a physical copy of business transactional records which is known as ledger where the ledger is identical which means every ledger that belongs to same channel must hold the same records.

            A ledger consists of two distinct, though related, parts – a world state and a blockchain. The world state – a database that holds current values of a set of ledger states. The blockchain – a transaction log that records all the changes that have resulted in the current the world state.

            A chaincode is the business logic that is used to read the records of ledger or to write new records into the ledger or to update existing records.

            A chaincode is consist with multiple smart contracts.

            So The convention is for each channel, you need an identical chaincode. If you have 2 channel, than it's the convention that you have two different chaincodes.

            Basically, error code 4 is when you try to initialize connection with blockchain (SUT) but failed, error code 5 is when you fail to install smart contract and error code 6 is for other errors (e.g configuration)
