Deploying contract using web3js fails

Question

I am trying to deploy contract using web3js in nodejs on ganache cli test server, but it fails with error as follows :

D:\Thrive\PoC\NodeWebAPI\node_modules\web3\lib\web3\contract.js:149
                                throw new Error('The contract code couldn\'t be stored, please check your gas amount.');
Error: The contract code couldn't be stored, please check your gas amount.

at XMLHttpRequest.request.onreadystatechange (D:\Thrive\PoC\NodeWebAPI\node_modules\web3\lib\web3\httpprovider.js:118:13)

The code snippet is as follows :

    var web3 = connection.getWeb3Object(config.BlockChainServer());

    var contractAbi = contractDetails.getContractAbi(contractName);

    var contractByteCode = contractAbi.bin;

    var gasEstimate = web3.eth.estimateGas({data: contractByteCode});

    console.log(gasEstimate);

    var contractObject = web3.eth.contract(contractAbi);

    var contract = contractObject.new({from: account, gas:1000000,data: "0x" + contractByteCode});

    var receipt = web3.eth.getTransactionReceipt(contract.transactionHash);

    if (receipt && receipt.contractAddress) {
        console.log("Your contract has been deployed at " + config.BlockChainServer + " | Contract address -" + receipt.contractAddress);
    }

I have tried sending varying amounts of gas, but I am encountering the same issue. What could be the problem ?

Answer 1

Remember gas value is always on Wei, try setting it to this value. 4712388 (which is truffle's default gas value). Also you could try deploying another small contract to check if the issue is with your blockchain or specific to this contract.

Answer 2

After trying out some more ways, I figured out the issue was due to not passing the proper byte-code information.The following piece of code was not correct.

var contractByteCode = contractAbi.bin;

I changed it to : var contractByteCode = contractAbi.Abi.bytecode;

Also, as @RobertC suggested in the earlier answer, deploying a smaller contract helped !
