Lesson 6: TypeError: yParity mismatch

[QingRun-Tan]

this is my depoly.js code

const { ethers } = require("hardhat");

async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("正在部署中！！！");

  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deployed();
  console.log(
    `simpleStorage address:${(await simpleStorage.getAddress()).toString()}`
  );
}

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

this is my hardhat.config.js code

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();

SEPOLIA_RPC_URL = process.env.SEPOLIA_RPC_URL;
SEPOLIA_PRIVATE_KEY = process.env.SEPOLIA_PRIVATE_KEY;
/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    sepolia: {
      url: SEPOLIA_RPC_URL,
      accounts: [SEPOLIA_PRIVATE_KEY],
      chainId: 11155111,
    },
  },
  solidity: "0.8.8",
};

this is my bug

@QingRun-Tan
i think it's the problem with hardhat .deployed() method this module may have been depreciated. try this see if this fix your issue

 async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("正在部署中！！！");

  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.waitForDeployment();// use .waitForDeployment() instead of .deployed()
  console.log(
    `simpleStorage address:${(await simpleStorage.getAddress()).toString()}`
  );

[minhktmd]

I have exactly same issue when deploying new contract
The error is thrown from deploy line
const simpleStorage = await SimpleStorageFactory.deploy();
I tried to comment out next line (await simpleStorage.deployed();) and nothing change. The error still apprear
The contract was deployed successfully. I checked blockchain explorer
Don't know why
