Unhandled rejection Error: This contract object doesn't have address set yet, please set an address first

Question

Im currently trying to use Infura to run on my machine thru Web3. When I set to run my node index.js file I get the following error:

Unhandled rejection Error: This contract object doesn't have address set yet, please set an address first.
    at Object._processExecuteArguments (/Users/Oso.Lu/cryptokitty-miner/node_modules/web3-eth-contract/src/index.js:739:15)
    at Object._executeMethod (/Users/Oso.Lu/cryptokitty-miner/node_modules/web3-eth-contract/src/index.js:760:54


var helpers = require("./helpers.js")

var Web3 = require('web3');
var Tx = require('ethereumjs-tx');

// You should be running a local Eth node or use Infura.
var web3 = new Web3(new Web3.providers.HttpProvider("https://mainnet.infura.io:443"));
var prompt = require('prompt');


var sendingAddress = "********************"  // with your sending ETH address
var pKey = "******************************"; // This will store the corresponding private key.  we'll be getting the private key for this Eth address from a command prompt


// Keep track of kitties we'll mine to avoid double-mining
var kittyArray = []

var theNonce = "";
// Gas price.   Todo: Use Eth gas station Oracle to predict gas prices
var gwei = '26'

// Track # of received
var num_requested = 0
var num_received = 0

I thought maybe the issue is running on Infura port 443.

This usually means you haven't set MyContract.options.address to the address returned from the contract instance after deployment. You'll need to post your complete code to confirm. – Chalky

Answer 1

Simple solution

Voting.options.address = "0x6ee9957aef5f4073c6af71441ec7962527c37671"

where Voting is my smart contract instance name

"0x6ee9957aef5f4073c6af71441ec7962527c37671" is deployed smart contact address

my web3.js version "web3": "^1.0.0-beta.31",

Sumption

where we have to write 'Voting.options.address = "0x6ee9957aef5f4073c6af71441ec7962527c37671"' ? – Hodgson

I have the same error that you got. Have you figure out where to add this code that @ngCourse recommend to add? – Brenner

Please mention the file where we need to add the above code. – Photophore

Answer 2

const accounts = await web3.eth.getAccounts()
this.setState({ 'account': accounts[0] });
const networkId = await web3.eth.net.getId()
const networkData = SocialNetwork.networks[networkId]
if (networkData) {
    const socialNetwork = web3.eth.Contract(SocialNetwork.abi, networkData.address)

} else {
    window.alert('oops')
}

This is the right way to set an address for your Contract. You can set the address by networkData.address

Thanks alot for this conversation, just started off with truffle in local environment and ran into this issue; It got solved , after this code in App.js `

const instance = new web3.eth.Contract(
        SimpleStorageContract.abi,
        deployedNetwork && deployedNetwork.address,
      );

` just addded this :

instance.options.address = " contract address on particular testnent ";

can be found in CONTRACT_NAME.js in networks where the network_id is 5777"

In my case, I realized that my directory was missing in my truffle-config.js file, which is why my networks field in migration.sol wasn't getting updated. I had to add the following line to fulfill the

contracts_build_directory: path.join(__dirname, "client/src/contracts"),
