Facing Some errors

[Asad-Stacker]

Hi
I am facing this error when I am running node deploy.js in my terminal , I am mentioning both my code and error, please have a look, I have done everything but as a newbie I cant catch up this error.. please explain me step by step as I cant catch whole thing directly...

Deploy.js(CODE):
const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
//http://127.0.0.1:7545 , http://172.19.16.1:7545 , 0x7d7f4bd6994e99ebeded9f02bfea5fb7c01690b2545d7cea4bcc876881db6e4e
//const provider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545");
const provider = new ethers.JsonRpcProvider("http://172.19.16.1:7545");
const wallet = new ethers.Wallet(
"0x366b355671cc19736b2366e2d6aa58a52ae2203f24c07c731d556a8732b59b55",
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");
const contract = await contractFactory.deploy();
await contract.deployTransaction.wait(1);
// const transactionReciept = await contract.deployTransaction.wait(1);

const currentFavoriteNumber = await contract.retrieve();
console.log(currentFavoriteNumber);
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});

ERROR:

Hi @Asad-Stacker
change

  await contract.deployTransaction.wait(1);  // for ethersV5

to this

  await contract.deploymentTransaction().wait();  // for ethersV6

Thanks a lot @alfaqi, you are such nice soul, it is impossible to completely learn this course without peoples like you, may god bless u!

@alfaqi I have downgraded by ether js version from 6 to 5 because I was facing many difficulties and error when writing the code, once my learning will be completed and I ll be familiar with coding then I will stay up to date

That's great! You can follow the course more easily, but you need to pay attention to the course's repository for any updates.
