Pleas some one help fix the error above

async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory(
    "SimpleStorage" // contract name
  );

  console.log("Deploying contract...");

  const simpleStorage = await SimpleStorageFactory.deploy();
  // await simpleStorage.deployed();

  console.log(`Deploying Address to ${simpleStorage.target}`); // target fetch the contract address.

  // if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
  //   await simpleStorage.deploymentTransaction().wait(6); // we are waiting so that the transaction get reflect on ethscan.
  //   await verify(simpleStorage.target, []);
  //   console.log(`contract verified!`);
  // }

  // Interact with the contract
  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}`);
}

If you deploy it locally, there is no problem with calling it directly after deployment, but there will be a problem when you go to the testnet, I don't know the specific details, but I can sleep for 10s after deployment and then interact with the contract.Add to the end of your contract deployment statement:await new Promise(resolve => setTimeout(resolve, 10000)).You can give it a try

This works for me, thanks, but I'm not sure why we need to sleep for 10s, it looks like there is a missing piece.

[mena234]

It looks like the missing piece is awaiting block confirmation

await simpleStorage.deploymentTransaction().wait(6);

[mena234]

I had the same issue, you need to wait for at least one confirmation block, before interacting with the contract, to be sure that i works you can wait for 6 confirmation blocks ( as in the video )

  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deploymentTransaction().wait(6); // ethers v6
  // await simpleStorage.deployTransaction.wait(6) // ethers v5
