NomicLabsHardhatPluginError: The constructor for contracts/FundMe.sol:FundMe has 1 parameters but 0 arguments were provided instead.

at 10:58:55 when I'm trying to deploy my contract on rinkeby testnet and trying to verify my contract on etherscan, I am getting this error and IDK what I''m doing wrong.

Nothing to compile
reusing "FundMe" at 0x2A0D25e07c111002d38924BFa804228cF27B8f1a
Verifying contract....
Nothing to compile
NomicLabsHardhatPluginError: The constructor for contracts/FundMe.sol:FundMe has 1 parameters
but 0 arguments were provided instead.

My Solidity "FundMe" contract source code is this.

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "./priceConverter.sol";

contract FundMe {
    using priceConverter for uint256;

    uint256 public minimumUSD = 50 * 1e18; // 1 * 10 ** 18
    address[] public Funders;

    mapping(address => uint256) public addrs_toamount_track;

    address public owner;

    AggregatorV3Interface public priceFeed;

    constructor(address priceFeedAddress) {
        owner = msg.sender;
        priceFeed = AggregatorV3Interface(priceFeedAddress);
    }

    function Fund() public payable {
        require(
            //1st_Arg...................(2nd_Arg)
            msg.value.getConvertionRate(priceFeed) >= minimumUSD,
            "Didn't send enough eth "
        );
        Funders.push(msg.sender);
        addrs_toamount_track[msg.sender] += msg.value;
    }

    function withdraw() public Onlyyowner {
        // require(msg.sender == owner,"Only owner can  call this function");
        /*starting index; ending index; step amount*/
        for (
            uint256 funderindex = 0;
            funderindex < Funders.length;
            funderindex += 1
        ) {
            address fundersagain = Funders[funderindex];
            addrs_toamount_track[fundersagain] = 0;
        }
        // reset the array
        Funders = new address[](0);
        (bool callsuccess, ) = payable(msg.sender).call{
            value: address(this).balance
        }("");
        require(callsuccess, "Call failed");
    }

    modifier Onlyyowner() {
        require(msg.sender == owner, "only owner can call this function");
        _;
    }
}

and my 01-deploy-fundme.js source code is this:

const { verify } = require("../Utils/verify");
const { network } = require("hardhat"); 

module.exports = async (hre) => {
  const { getNamedAccounts, deployments } = hre;
  const { deploy, log } = deployments;
  const { deployer } = await getNamedAccounts();
  const chainId = network.config.chainId;
  
  const {
    networkConfig,
    developmentChains,
  } = require("../helper-hardhat-config");
 
  let ethUsdPriceFeedAddress;
  if (developmentChains.includes(network.name)) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator");
    ethUsdPriceFeedAddress = ethUsdAggregator.address;
  } else {
    ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"];
  }

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

  // #VERIFICATION
  if (
    !developmentChains.includes(network.name) &&
    process.env.ETHERSCAN_API_KEY
  ) {
    await verify(fundMe.address, args);
  }
  log("_______________________________________________");
};

module.exports.tags = ["all", "waqar"];

I've also tried to place [ethUsdPriceFeedAddress] directly in args: but it still doesn't work shows the same error .

here is my helper-hardhat-config.js script as well:

const networkConfig = {
  4: {
    name: "rinkeby",
    ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
  },
  137: {
    name: "polygon",
    ethUsdPriceFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
  },

};

const developmentChains = ["hardhat", "localhost"];
const DECIMALS = 8;
const INITIAL_ANSWER = 200000000000;

module.exports = { networkConfig, developmentChains, DECIMALS, INITIAL_ANSWER };

if you want any other source code to as well, mention in comments and I'll show that as well.

Hey @OmarWaqar123 please share your verify.js code.

[OmarWaqar123]

hi @othaime-en here is my verify.js script

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

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

module.exports = { verify };

[OmarWaqar123]

@othaime-en if you find any solution to this, please let me know

[othaime-en]

@OmarWaqar123 there is a typo here: constructorArguements it should be constructorArguments
That's what is causing the error.

[OmarWaqar123]

Thanks @othaime-en it was indeed a typo , and it is now fixed and my contract is verified :)

Push to GitHub and reply w/ the link.

[OmarWaqar123]

????

[krakxn]

?

[OmarWaqar123]

@krakxn Idon't understand what do you mean by push to Github and reply w/ the link it's probably because I don't know much about github . also I am stuck right now at 10:58:55 of the video and Patrick haven't showed how to push your code to github. is there any other way of solving this error??

[krakxn]

Oh, no problem. Try @othaime-en 's fix first :)

[OmarWaqar123]

yeah @krakxn it was a typo, my mistake :)
