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        console.log(`Withdrawn........`)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.
