Error: factory runner does not support sending transactions (operation="sendTransaction", code=UNSUPPORTED_OPERATION, version=6.7.1)

Question

I have run into the above error trying to deploy my contract. Running npx hardhat scripts/deploy.js. Here is the deploy.js:

async function main() {

    const Test1 = await ethers.getContractFactory("Test1");
  
  
    // Start deployment, returning a promise that resolves to a contract object
  
    const test1 = await Test1.deploy()
  
    await test1.waitForDeployment()
  
    console.log("Contract deployed to address:", test1.address)
  
  }
  
  
  main()
  
    .then(() => process.exit(0))
  
    .catch((error) => {
  
      console.error(error)
  
      process.exit(1)
  
    })

Here is my hardhat.config:

/** @type import('hardhat/config').HardhatUserConfig */
require("@nomiclabs/hardhat-ethers");
require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();


const { API_KEY, PRIVATE_KEY } = process.env;

module.exports = {
  solidity: "0.8.19",
    defaultNetwork: "sepolia",
    networks: {
      sepolia: {
        url: `${API_KEY}`,
        account: [`0x${PRIVATE_KEY}`],
        gas: 2100000,
        gasPrice: 8000000000,
        saveDeployments: true,
      }
    }
};

Also, I am 100% sure that my keys are working because this index.js script:

async function main() {
  const latestBlock = await ethers.provider.getBlock("latest");
  console.log("The latest block number is", latestBlock);
}

main();

returned this without issue:

The latest block number is Block {
  provider: HardhatEthersProvider {
    _hardhatProvider: LazyInitializationProviderAdapter {
      _providerFactory: [AsyncFunction (anonymous)],
      _emitter: [EventEmitter],
      _initializingPromise: [Promise],
      provider: [BackwardsCompatibilityProviderAdapter]
    },
    _networkName: 'sepolia',
    _blockListeners: [],
    _transactionHashListeners: Map(0) {},
    _eventListeners: []
  },

and I am seeing this reflected in my API.

I am seeing transactions on my API long after I try to run the deploy script but it doesn't seem to have actually done anything. THAT transaction method on my API is called eth_accounts and they are empty.

Your hardhat.config.js:

accounts: [`0x${PRIVATE_KEY}`],

plural 'accounts', not singular 'account'
