Lesson 7 - The 'address' parameter of task 'verify:verify' expects a value, but none was passed.

[zhikri]

Hi,
I got issue while deploying fundme.js on testnet, contract address still undefined after deploy fundme function called then it causes fundme.address couldn't be passing to verify parameter. I have looking for online search in stack and this github discussion but i coudn't figured out what wrong with my code.

here is the deploy fundme script

const fundMe = deploy("FundMe", {
    from: deployer,
    args: [ethUsdPriceFeedAddress], //price feed
    log: true,
    waitConfirmation: network.config.blockConfirmations || 1,
  });
  log(`deployed to: ${fundMe.address}`);

  if (
    !developmentChains.includes(network.name) &&
    process.env.ETHERSCAN_API_KEY
  ) {
    await verify(fundMe.address, [ethUsdPriceFeedAddress]);
  }

and here is whats the errors look like

@zhikri : Show me your verify.js file and your complete 01-fund-me-deploy.js file!

[zhikri]

here is my verify.js

const { run } = require("hardhat");

const verify = async function verify(contractAddress, args) {
  console.log("Verifying contract...");
  try {
    await run("verify:verify", {
      address: contractAddress,
      constructorArguments: args,
    });
  } catch (e) {
    if (e.message.toLowerCase().includes("already verified")) {
      console.log("Already Verified!");
    } else {
      console.log(e);
    }
  }
};

module.exports = { verify };

and here is complete script of fundme.js

const {
  networkConfig,
  developmentChains,
} = require("../helper-hardhat-config");
const { network } = require("hardhat");
const { verify } = require("../utils/verify");
require("dotenv").config();

module.exports = async ({ getNamedAccounts, deployments }) => {
  const { deploy, log } = deployments;
  const { deployer } = await getNamedAccounts();
  const chainId = network.config.chainId;

  let ethUsdPriceFeedAddress;
  if (developmentChains.includes(network.name)) {
    const usdEthAggregator = await deployments.get("MockV3Aggregator");
    ethUsdPriceFeedAddress = usdEthAggregator.address;
  } else {
    ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"];
  }

  const fundMe = deploy("FundMe", {
    from: deployer,
    args: [ethUsdPriceFeedAddress], //price feed
    log: true,
    waitConfirmation: network.config.blockConfirmations || 1,
  });
  log(`deployed to: ${fundMe.address}`);

  if (
    !developmentChains.includes(network.name) &&
    process.env.ETHERSCAN_API_KEY
  ) {
    await verify(fundMe.address, [ethUsdPriceFeedAddress]);
  }
};
module.exports.tags = ["all", "fundme"];

@zhikri : Yup you didn't add await in deploying your contract.

Correct this from this : const fundMe = deploy("FundMe", { ---> To this : const fundMe = await deploy("FundMe", {

That's why the error is coming : The 'address' parameter of task 'verify:verify' It expects a value, but none was passed!

That should fix it!

[zhikri]

Thankyouu! now it's works

@zhikri add await before deploy function

const fundMe = await deploy("FundMe", {
    from: deployer,
    args: [ethUsdPriceFeedAddress], //price feed
    log: true,
    waitConfirmation: network.config.blockConfirmations || 1,
  });

I am facing same problem
my verify.js code is "const { run } = require("hardhat")

const verify = async (contractAddress, args) => {
console.log("Verifying contract...")
try {
await run("verify:verify", {
address: contractAddress,
constructorArguments: args,
})
} catch (e) {
if (e.message.toLowerCase().includes("already verified")) {
console.log("Already verified!")
} else {
console.log(e)
}
}
}

module.exports = { verify }"

and 01-deploy.js is "const { getNamedAccounts, deployments } = require("hardhat");
const { networkConfig, developmentChains } = require("../helper-hardhat-config");
const {network} = require("hardhat");
const {verify} = require("../utils/verify")

module.exports = async ({getNamedAccounts, deployments}) => {
const {deploy, log} = deployments
const {deployer} = await getNamedAccounts()
const chainId = network.config.chainId

// const ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
let ethUsdPriceFeedAddress
if(developmentChains.includes(network.name)) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator")
    ethUsdPriceFeedAddress = ethUsdAggregator.address
}
else{
    ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
}
const arg = ethUsdPriceFeedAddress

const fundMe = await deploy("FundMe", {
 from: deployer,
 args: [arg],
 log: true,
 waitConfirmations: network.config.blockConfirmations || 1, 
})

if(!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY){
    await verify(fundMe.address.ethUsdPriceFeedAddress)
}

console.log("-----------------------------------------")

}

module.exports.tags = ["all","fundme"]" and here is my error "HardhatError: HH306: The 'address' parameter of task 'verify:etherscan' expects a value, but none was passed."
