hey? did you find any solution to this? here is my code, can you tell me where am i going wrong? I know this error is during deployment of the contract.

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

async function main() {

const provider = new ethers.providers.JsonRpcProvider("HTTP://127.0.0.1:7545"); // saying hey we want to connect to this url.
// console.log(provider);
// now lets get the private keys and address,
const wallet = new ethers.Wallet(
    "0x980e8856975093bb103514dbe464d6f274cc1f03a30b8a9a18c4cb64b772ac66",
    provider
);

// console.log(wallet);

// now to interact with any contract we need 2 things as we know: Address and ABI
const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
// console.log(abi);
const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
);

const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
const overrides = { gasLimit: 6600000  }; 
const contract = await contractFactory.deploy(overrides);
// console.log(contract);
const deploymentReceipt = await contract.deployTransaction.wait(1); // wait for one more block to add in chain before confirmation of this block
const currentFavoriteNumber = await contract.retrieve();
console.log(currentFavoriteNumber);

}

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

Try this @RohitGhosh7703 I fixed this error by

Uninstall solc, then reinstall solc@0.8.7-fixed. Deleting both abi & bin files from your directory. Recompile the contract to generate abi & bin files.
