hey,

i am getting this error while deploying my contract.

async function main() {
    // First, compile this!
    // And make sure to have your ganache network up!
    const provider = new ethers.JsonRpcProvider("http://127.0.0.1:8545");
    const wallet = new ethers.Wallet("0x9ed7673fdaaf656f6f0d460e9590ff6cc65f8270179e1e4866d59dfbc55f278f", provider);
    // const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf8");
    // let wallet = new ethers.Wallet.fromEncryptedJsonSync(
    //   encryptedJson,
    //   process.env.PRIVATE_KEY_PASSWORD
    // );
    // wallet = wallet.connect(provider);
    const abi = fs.readFileSync("./simplestorage_sol_SimpleStorage.abi", "utf8");
    const binary = fs.readFileSync("./simplestorage_sol_SimpleStorage.bin", "utf8");
    const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
    console.log("Deploying, please wait...")
    const contract = await contractFactory.deploy();
    const deploytransaction = await contract.deployTransaction
    let currentFavoriteNumber = await contract.retrieve()
    console.log(`Current Favorite Number: ${currentFavoriteNumber}`)
}

Please help!!!

Thanks in advance

Right now i am in etherssimplestorage

@Sharma7Prateek You forgot the parenthesis;

-await contract.deployTransaction
+await contract.deployTransaction()

[Sharma7Prateek]

Oops! sorry i forgot to mention but the problem remains the same.
I am not getting such error while deploying my contract using hardhat

[alymurtazamemon]

@Sharma7Prateek I did not understand. Is it resolved?

Hello.
I had the same issue which might be because of the ethers version (I'm not sure the reason) but I have the solution.

Instead of contract.deployTransaction() you should use contract.deploymentTransaction()

Before:

const contract = await contractFactory.deploy();
const deploytransaction = await contract.deployTransaction

After:

const contract = await contractFactory.deploy();
const deploytransaction = await contract.deploymentTransaction().wait();
console.log("contract deployed to: ", deploytransaction.contractAddress)

This should work. Please let me know :)
