Lesson 8: FUND ME(FULL STACK) withdraw function is not wotking

[olaoyesalem]

My fund function is working and the website is connected to my metamask

, but anytime I try to withdraw ETH from the contract by
calling the withdraw function ,

async function withdraw(){
    if(typeof window.ethereum !== "undefined"){
        console.log(` Withdrawing!!!!!!!!!!!`)
        console.log(`-------------------------------------`)
        const provider = new ethers.providers.Web3Provider(window.ethereum)
        const signer = provider.getSigner();
        const contract = new ethers.Contract(contractAddress,abi,signer)
        const txnResponse = await contract.withdraw();
        await listenForTxnMine(txnResponse,provider);
        console.log(`-------------------------------------`)
        console.log(`Withdrawn........`)
        
    }
}

I get an error

Please, I need help.

what does the solidity function look like? and can u expand the metamask error so we can see the message

I am facing the same issue, could you elaborate..

Okay. once you deployed your contract in hardhat environment, you have connected an accounts from the 20 accounts hardhat gives us.

According to my withdraw function

 function withdraw()public onlyOwner{
        for(uint i=0; i<funders.length; i++){
            addressToAmountFunded[funders[i]]=0;
        }
        funders = new address[](0);
        (bool callSuccess, )=payable(msg.sender).call{value: address(this).balance}("");
            require(callSuccess,"call Failed");
    }

modifier onlyOwner(){
    require(msg.sender==i_owner);
    _;
}

only the owner of thee contract i.e. the person who deployed the contract can call the withdraw function.

Now, the mistake I made then was that, I deployed the contract with account zero from the accounts on hardhat.

Account #0: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 (10000 ETH)
Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

but when I wanted to interact with the smart contract from the front-end, I used account 10

Account #10: 0xBcd4042DE499D14e55001CcbB24a551F3b954096 (10000 ETH)
Private Key: 0xf214f2b2cd398c806f84e317254e0f0b801d0643303237d97a22a48e01628897

And according to the smart contract only the person who deployed the contract can withdraw , so only

Account #0: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 (10000 ETH)
Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

can withdraw.

So, metamask reverted with a bunch of errors

thanks @olaoyesalem . Your explanation is fantastic. It got me unstuck. 👍

Thanks for the explanation @olaoyesalem!
I have the same issue, however, how can I modify the code to use account #3 for example?

[sebaszeledon]

Actually, I already resolved it :D Thank you!
