TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

[ejmorian]

I'm having difficulty figuring out why the JsonRpcProvider is not working properly, I've had a look around and most answers i've read suggest to downgrade the ethers js version to 5.7. i'm currently using 6.2

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

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

    const wallet = new ethers.Wallet("0xb112e3303c9e9c9b61fc2627787704424c2d399a63b3d2e4853c7bd7701ea749", 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(); // stop here, wait for contract to finish
    console.log(contract);
}

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

is there another way to get this working without downgrading?

@ejmorian Yes, the latest version syntax is like this ethers.JsonRpcProvider, but I would still recommend using a version below 6. Because from lesson 6 you will be using hardhat-deploy dependency which is not updated to version 6 and ethers version 6 is still in beta.

@uzairAhsan99 Please leave your repository link, I need to test it locally.

Thank you so much, your method worked perfectly, here is the link kindly have a look:

[alymurtazamemon]

@uzairAhsan99 update this line;

- const contractFactory = ethers.ContractFactory(abi, binary, wallet);
+ const contractFactory = new ethers.ContractFactory(abi, binary, wallet);

after this you will get the error Error: could not detect network for this check it out this discussion #286
