Lesson 6: Error: incorrect number of arguments to constructor

[themalaysianguy]

Hi,

I'm at Lesson 6: Part 4 towards the end where Patrick was demonstrating the contract deployment. However, after trying to deploy, I received this error below.

Error: incorrect number of arguments to constructor

and also...

error Command failed with exit code 1.

Below is my SimpleStorage sol contract:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.9;

// Uncomment this line to use console.log
// import "hardhat/console.sol";

contract SimpleStorage {
    uint public unlockTime;
    address payable public owner;

    event Withdrawal(uint amount, uint when);

    constructor(uint _unlockTime) payable {
        require(
            block.timestamp < _unlockTime,
            "Unlock time should be in the future"
        );

        unlockTime = _unlockTime;
        owner = payable(msg.sender);
    }

    function withdraw() public {
        // Uncomment this line, and the import of "hardhat/console.sol", to print a log in your terminal
        // console.log("Unlock time is %o and block timestamp is %o", unlockTime, block.timestamp);

        require(block.timestamp >= unlockTime, "You can't withdraw yet");
        require(msg.sender == owner, "You aren't the owner");

        emit Withdrawal(address(this).balance, block.timestamp);

        owner.transfer(address(this).balance);
    }
}

And below is my deploy.js code:

//imports
const { ethers } = require("hardhat")

//async main
async function main() {
    const SimpleStorageFactory = await ethers.getContractFactory(
        "SimpleStorage"
    )
    console.log("Deploying contract...")
    const simpleStorage = await SimpleStorageFactory.deploy()
    await simpleStorage.deployed()
}

//main
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

Please help me out, let me know if more info is required.

Found the fix to this. I found a similar problem here.

Due to the updated documentation of ethers to V6, all I had to do was change deployed() to waitForDeployment() as below:

async function main() {
    const SimpleStorageFactory = await ethers.getContractFactory(
        'SimpleStorage'
    )
    console.log('Deploying contract...')
    const simpleStorage = await SimpleStorageFactory.deploy()
    console.log('Waiting for contract to be deployed...')
    await simpleStorage.waitForDeployment()
    console.log(`Deployed contract to: ${simpleStorage.target``}`)
}

Also, note that the last line is .target instead of .address:

 console.log(`Deployed contract to: ${simpleStorage.target``}`)

Some info about the difference between .address and .target here
