Lesson 6 - TypeError: Cannot read properties of undefined (reading 'wait') -

TypeError: Cannot read properties of undefined (reading 'wait')

hello, I unable to deploy my contract for some issues like for example, deployed() keyword changed to waitForDeployment(), now I have the same issue in my terminal but with another function:

 // update transaction
    const transactionResponse = await simpleStorage.store(7)
    await transactionResponse.wait(1)
    const updatedValue = await simpleStorage.retrieve()
    console.log(`updated value is: ${updatedValue}`)
}

---

I checked in the simpleStorage part, however I realized that deployTransaction.wait(6) could has an error

console.log(`Deployed contract to: ${simpleStorage.target}`)
    if (network.config.chainId == 11155111 && process.env.ETHERSCAN_API_KEY) {
        console.log("waiting for the block taxes   ")
        await simpleStorage.deployTransaction.wait(6)
        await verify(simpleStorage.address, [])
    }

I know because the error jumps after console.log("waiting for the block taxes ") in the terminal

I suspect that probably ethers.getContractFactoryHas a different function, however is not the same as deployTransaction.wait
and if is it correct. How can I fix this issue?

Hey @herculeskan ! I had the same issues with hardhat network on my local machine.
You can try checking the name of Contract.sol filename and the name inside the contract is same i.e.

Contract <Contract_name>{

}

the deployed is a runner function which might give error based on versions . Instead just use the .deploy();
Just check if the names of function in the .sol file are same as your js functions you are calling.

Hi @herculeskan,
You have to change await simpleStorage.deployTransaction.wait(6)
by
await simpleStorage.deploymentTransaction().wait(6)

And it could work :)

this works

works, thanks!

This worked for me also. Instead of using await simpleStorage.deployTransaction().wait(6) like in the video .. use await simpleStorage.deploymentTransaction().wait(6)
Thank you!
