error .env not working

[jeevansiddu]

I have tried to fetch from .env file but i have no idea why it is not working ., if I directly add the rpc url in the placeholder it is working but when used with .env not working

My js file

const ethers = require("ethers");
const fs = require("fs");
require("dotenv").config();
async function main() {
  const provider = new ethers.providers.JsonRpcProvider(
    process.env.RPC_URL_GOERLI
  );
  const wallet = new ethers.Wallet(
    "0x40f7a1ccf6a0d176030bb7a8fc44b74297f49ba2e7b268b7c82172a9607e7ff",
    provider
  );
  const abi = fs.readFileSync("./crowdfunding_sol_CrowdFunding.abi", "utf8");
  const bin = fs.readFileSync("./crowdfunding_sol_CrowdFunding.bin", "utf8");
  const contractfactory = new ethers.ContractFactory(abi, bin, wallet);
  console.log("Deploying ,please wait !!!");
  const contract = await contractfactory.deploy();

  await contract.deployTransaction.wait(1);
  console.log(`${contract.address}`);
}
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

package .json file

{
  "dependencies": {
    "dotenv": "^16.0.3",
    "ethers": "5.7.2",
    "fs": "^0.0.1-security",
    "solc": "0.8.7-fixed"
  },
  "scripts": {
    "compile": "yarn solcjs --bin --abi --include-path node_modules/ --base-path . -o . crowdfundingpa.sol "
  }
}

error :

hello make sure your .env file is located in the root directory of you project , if that is done you can try troubleshooting by adding a console.log(process.env) statement in your code to print out all of the environment variables and check if RPC_URL_GOERLI is present.

[alymurtazamemon]

@jeevansiddu First of all do not use goerli now, see this announcement #5079. And once you start to use sepolia, make sure that your env file name is .env, it is at the root level of the project, and the RPC URL name should have not space SEPOLIA_RPC_URL=your-url-here

[jeevansiddu]

Hey thanks for your replies sure I will change it to sepolia very soon my .env file is in the root directory and console.log(process.env) is working

but even after checking it if I type process.env.RPC_URL_GOERLI IT IS NOt working

[jeevansiddu]

And one more question whhy we changed the faucet to sepolia for me goerli works fine , and it didnt cost any real money right

[jeevansiddu]

any answers please reply???

[alymurtazamemon]

@jeevansiddu Please read my given discussion link to read about why we moved to sepolia.

And about your error, so it throws could not detect network error, it means either you are not using the correct rpc URL or it has typos. Can you show me your .env file? Please hide your keys especially private key.

[jeevansiddu]

please can someone answer

[jeevansiddu]

yeah thank you it actually worked ., I had issues on the dev dependancy file in hardhat.config file ., it is now resolved
