Lesson 6: hardhat simple storage. Getting ProviderError: Must be authenticated!

[003-kalki]

Deploy.js code :

// imports
const { ethers, run, network } = require("hardhat");

// async main
async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("Deploying contract...");
  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deployed();
  console.log(`Deployed contract to: ${simpleStorage.address}`);
  // what happens when we deploy to our hardhat network?
  if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
    console.log("Waiting for block confirmations...");
    await simpleStorage.deployTransaction.wait(6);
    await verify(simpleStorage.address, []);
  }

  const currentValue = await simpleStorage.retrieve();
  console.log(`Current Value is: ${currentValue}`);

  // Update the current value
  const transactionResponse = await simpleStorage.store(7);
  await transactionResponse.wait(1);
  const updatedValue = await simpleStorage.retrieve();
  console.log(`Updated Value is: ${updatedValue}`);
}

You did not set a valid API key. recheck your api key in the .env.example or .env file and make sure it is correct. I am see you are using a wrong api in here
