FIXED: Solving issues between ethers v5 used in course and ethers v6

[cyberws]

Hi folks,

Thought I would share my experience with Lesson 5 and the issues caused by video using v5.6.2 and current version of ethers being v6.x.x

For ethers v5.6.2 (as shown in the video) the following commands are used to connect to Ganache

const provider = new ethers.providers.JsonRpcProvider("http://172.23.48.1:7545");

For ethers v6.7.1 (at the time of writing this) use:-

const provider = new ethers.JsonRpcProvider("http://172.23.48.1:7545");

You can use the same commands as the video by using:-

yarn add [email protected]

To force the version of ethers to be v5.6.2

By using ethers v5.6.2 the output from the

  console.log(contract);

Is much more verbose (like in the video), and shows Contract output rather than the much briefer BaseContract data that ethers v6.x.x outputs

For the rest of this lesson the syntax changes between 5 and 6 are as follows.

For ethers v5.6.2

const transactionReceipt = await contract.deployTransaction.wait(1);
console.log(contract.deployTransaction);
const nonce = await wallet.getTransactionCount();
const encryptedJsonKey = await wallet.encrypt(
    process.env.PRIVATE_KEY_PASSWORD,
    process.env.PRIVATE_KEY
);
let wallet = new ethers.Wallet.fromEncryptedJsonSync(
  encryptedJson,
  process.env.PRIVATE_KEY
);

For ethers v6.7.1

const transactionReceipt = await contract.deploymentTransaction().wait(1);
console.log(contract.deploymentTransaction());
const nonce = await wallet.getNonce();
const encryptedJsonKey = await wallet.encrypt(
    process.env.PRIVATE_KEY_PASSWORD
);
let wallet = ethers.Wallet.fromEncryptedJsonSync(
  encryptedJson,
  process.env.PRIVATE_KEY
);

Hope this helps others.

Great!
If you are stuck anywhere in the future. You can refer to my repositories, they are made with ethers v6.

Hi
In lesson 5 time ((07:08:39):) when Patrick hits node deploy.js I am currently over there and facing some difficulties, when I hit node deploy.js it gives me an error, I have checked my Ganache its on the same RPC network on same port also running in the back but still facing this error, I doubled checked everything!

asad124@DESKTOP-I9II3SB:~/ethers-simple-storage-fcc$ node deploy.js
Deploying, Please wait..
JsonRpcProvider failed to detect network and cannot start up; retry in 1s (perhaps the URL is wrong or the node is not started)
Error: connect ECONNREFUSED 127.0.0.1:7545
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16) {
errno: -111,
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 7545

BELOW IS MY CODE

const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
//http://127.0.0.1:7545
//const provider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545");
const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
const wallet = new ethers.Wallet(
"0x5b1a8927914faab9bf27cb4dfa3e1edec9ad10358e62b1199bfa4845c5d9a048",
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();
console.log(contract);
}

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

In my case

I use the "WSL (UBUNTU) in my "VS Code", therfore to solve this problem.

I went to settings after => to server tab => and changed my hostname to ".... (WSL (Hyper-V firewall))

Thanks a lot brother. this error took me roughly 7 hours to solve 😅
