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

[abdullahtanvir11]

I got this error while verifying on etherscan while my other code ran successfully.
I think this line is giving the error.

Hey @abdullahtanvir11 please share the terminal where you are getting the error. Makes it easy to debug the problem

Hey @abdullahtanvir11 the error seems to come from your deploy script. Please share it here I look into it

[abdullahtanvir11]

const { verifyMessage } = require("ethers/lib/utils")
const { ethers, run, network } = require("hardhat")

async function main() {
const StorageFactory = await ethers.getContractFactory("SimpleStorage")
console.log("Deploying Contract...")
const simpleStorage = await StorageFactory.deploy()
await simpleStorage.deployed()
console.log("Deployed Contract to:" + simpleStorage.address)

if (network.config.chainId === 5 && process.env.ETHERSCAN_API_KEY) {
    await simpleStorage.deployTransaction.wait(6)
    await verify(simpleStorage.address, [])
}

// Update the current value
const transactionResponse = await simpleStorage.store(5)
await transactionResponse.wait(1)
const updatedValue = await simpleStorage.retrieve()
console.log(`Updated Value is: ${updatedValue}`)

}

async function verify(contractAddress, args) {
console.log("Verifying Contract...")

try {
    await run("verify:verify", {
        address: contractAddress,
        constructorArguments: args,
    })
} catch (e) {
    if (e.message.toLowerCase().includes("already verified")) {
        console.log("Already Verified!")
    } else {
        console.log(e)
    }
}

}

main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error)
process.exit(1)
})

@abdullahtanvir11 : Follow the steps, I'm listing below,

• First Copy & Paste the dependencies I'm giving you below in your package.json file, And remove your's.
• After that run the command : yarn hardhat clean
• Then delete your node_modules folder.
• After that in your terminal run the command : yarn To install the new dependencies.
• After installing dependencies run : yarn hardhat compile

Then deploy your script : yarn hardhat run scripts/deploy.js --network goerli

{
  "dependencies": {
    "@nomiclabs/hardhat-ethers": "^2.0.4",
    "@nomiclabs/hardhat-etherscan": "^3.0.0",
    "@nomiclabs/hardhat-waffle": "^2.0.2",
    "chai": "^4.3.4",
    "ethereum-waffle": "^3.4.0",

Let me know, If it resolves your issue!

[abdullahtanvir11]

Yes it is working now. Thankyou very much :)
Can you tell what is the problem actually?

@abdullahtanvir11 : It was the dependencies issue! I think you were missing some of them!
