deployTransaction.wait(1) Not working

[Mr-Ahmadi]

Hey, I'm using ethers": "^6.1.0, and deployTransaction.wait(1) function is not found for me. Is there any alternative function available for it?!

async function main() {
  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  const wallet = new ethers.Wallet(
    "0x4e669b793198a13fc2bd3c5693da8ac121428afea0eb9dd6dd986b632e903130",
    provider
  );

  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const bin = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8");
  const contractFactory = new ethers.ContractFactory(abi, bin, wallet);
  console.log("Deploying...\n");
  const contract = await contractFactory.deploy();
  await contract.deployTransaction.wait(1); // Doesn't work (TypeError: no matching function)
  console.log(contract);
}

@Mr-Ahmadi Hey reach out to the etherjs team on their GitHub repo for any issues if you want to use version 6 and above, but because version 6 is in beta here we are suggesting everyone use the version below 6.

And I also suggest you to use the same package.json file from the course repos while learning so your learning process can be smooth later you can move to updated versions.

Hi @alymurtazamemon I have the same issue despite the same ether version in the package.json as the course.

const ethers = require("ethers");
const fs = require("fs-extra"); // to read the ABI and binary file to deploy the contract

async function main() {
  // ganache chain RPC: http://127.0.0.1:7545
  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  const wallet = new ethers.Wallet(
    "0cd3dfbc1c1111b242c72d033ca4322769a03d0707d0966f8e8d4359089fda02",
    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(); // STOTP here. Wait for the contrtact to get deployed.
  console.log(contract);

  const deploymentReceipt = await contract.deployTransaction.wait(1); // to wait for 1 block creation to ensure that it's added to the blockchain
  console.log(deploymentReceipt);
}

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

NVM I was able to fix it. I had to downgrade ethers to 5.5.3

yarn add ethers@5.5.3

[heheboii11]

just chech the syntax of the code, it should be like this
await simplestorage.deploymentTransaction().wait(1)
you missed () after transaction thats it
