Provider: missing new

[smrkarkii]

While deploying my contract, following error occurs.

Here's the code of deploy.js. Please help me solve it.
`const ethers = require("ethers");
const fs = require("fs");

async function main() {
//http://127.0.0.1:7545
const provider = ethers.providers.JsonRpcProvider("http://127.0.0.1:7545");
const wallet = new ethers.Wallet(
"0xc2edadc0963b324f4cb311c0a00784117ec7a483",
provider
);
//abi -> how to interact with the contract
//binary -> compiled code
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");
const contract = await contractFactory.deploy(); //wait for contract to deploy
console.log("contract");
}

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

Well check the beginning:

const provider = ethers.providers.JsonRpcProvider("http://127.0.0.1:7545/");

You need to create a new instance, as the error code tells you, at main, in deploy.js: line 6.

So you can change it to:

const provider = new ethers.providers.JsonRpcProvider("http://127.0.0.1:7545/");

Great work!

To clarify, we need the new keyword here because of this:

export class JsonRpcProvider extends BaseProvider {

It is used as so for the creation of objects; in this case, it is JsonRpcProvider.
