Lesson5 : Getting a error while trying to deploy my contract

[yadavkundan516601]

const ethers =require("ethers");  // require is a funcruion to import ethers package
const fs=require("fs");

async function main()
{
   // http://127.0.0.1:7545
   const provider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545"); //way to connect to local blockchain
   const wallet= new ethers.Wallet("0e2be15bab52aba565caa88f164fd4dfc470d4b5ab4f0c4e7b8b69ec558de072",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)
    })

I`m getting a error TypeError: ethers.wa is not a constructor
at main (/home/yaduvanshi/Desktop/Block-chain/Contract/Deploy.js:8:18)
at Object. (/home/yaduvanshi/Desktop/Block-chain/Contract/Deploy.js:19:1)

While i am trying to deploy my first contract using js

Hi! From the error you are showing us said: that in the contract that you named "Deploy.js" on the line number 8 there is an error.
Check that something was write wrong: "ethers.wa"
You could also paste that code here in order to see it. Thanks :)

@yadavkundan516601 try this
const fs = require("fs-extra");

also check the spacing you use in your code such as here
const ethers =require("ethers");
const abi= fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi","utf8");

and here as well as space between parameters
const contractFactory= new ethers.ContractFactory(abi,binary,wallet);

Syntax is very strict, so just 1 thing out of place can throw the entire code off.

Also, in case you run into trouble with RPC make sure you select vWSL RPC in ganache server and make sure you are on 8545 instead of 7545.

Hope this helps!

you are not getting the result because you are not using an object of ContractFactory but you're using ContractFactory in itself to deploy it. If you intend to keep doing it that way, write ContractFactor(abi,bytecode,wallet)
and if not, just lowercase the C in const contract = await ContractFactory.deploy();
Hope this resolves your query.
