const provider = new ethers.providers.Web3Provider(window.ethereum);

const signer = provider.getSigner("RANDOM_WALLET_ADDRESS"); // Add a random wallet address here

const contract = new ethers.Contract(


It takes a couple of hours to resolve this issue; I hope you will fix it in less than 5 minutes.
