Lesson 5: Error:could not coalesce error ->while executing contract.store("42") function

[SanmeetShah]

Here's my deploy.js

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

async function main(){
    // rpc url for ganache HTTP://127.0.0.1:7545
    const provider=new ethers.JsonRpcProvider("HTTP://127.0.0.1:7545");
    const wallet=new ethers.Wallet("0x27e8be2828f894d7e64b14dc6f573e44ad8f49c1d4ea752b5978033809a8e6b1",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 Contract...");
    const contract=await contractFactory.deploy({ gasPrice: 20000000000, gasLimit: 6721975 });

   const currentFavoriteNumber=await contract.retrieve();
   console.log(`Number : ${currentFavoriteNumber.toString()}`);
   const transactionResponse=await contract.store("42");
   const transactionReceipt=await transactionResponse.wait(1);
   const updatedFavoriteNumber=await contract.retrieve();
   console.log(`Updated Number : ${updatedFavoriteNumber.toString()}`);
}

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

Here's the error

Using const contract = await contractFactory.connect(wallet);
instead of const contract=await contractFactory.deploy({ gasPrice: 20000000000, gasLimit: 6721975 }); worked for me, please try yourself and let me know whether your problem is solved or not.
