Lesson 6: TypeError: no matching function... deployTransaction

[TrudyCyns]

I get the following error trying to verify the SimpleStorage contract:
TypeError: no matching function (argument="key", value="deployTransaction", code=INVALID_ARGUMENT, version=6.6.3)

This is my main function from deploy.ts:

async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("Deploying SimpleStorage...");

  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.waitForDeployment();
  console.log(
    "Contract deployed to address: ",
    await simpleStorage.getAddress()
  );

  if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
    console.log("Waiting for 5 blocks to be mined...");
    await simpleStorage.deployTransaction.wait(5); //wait is flagged as not existing on deployTransaction
    await verify(simpleStorage.address.toString(), []);
  }
}

To be more specific, the error on the line containing wait() is:
Property 'wait' does not exist on type 'BaseContractMethod<any[], any, any>'.

deployTransaction is in ethersV5 and you are using ethersV6
use waitForDeployment() instead of deployTransaction

  if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
    console.log("Waiting for 5 blocks to be mined...");
    await simpleStorage.waitForDeployment();
    await verify(simpleStorage.address.toString(), []);
  }

Thank you for the response.
This removes the error but it seems by the time this line is reached, the bytecode has not registered yet on the block explorer, given the following message I get:

Reason: The Etherscan API responded that the address 0x961E9662701388b3B8addB9Dfa7bA09c074dc81a 
does not have bytecode. 
This can happen if the contract was recently deployed and this fact hasn't propagated to the backend yet. 
Try waiting for a minute before verifying your contract. 
If you are invoking this from a script,try to wait for five confirmations of your contract deployment transaction 
before running the verification subtask.

Is there a way to achieve the 5 block confimation wait?

[alfaqi]

You have more than way,
one way, using ethersJS wait method,
another way, using Javascript sleep method.
or manually, deploy, wait about one minute, then verify the contract.
