[jorgect207]

some can help me with that?

const { ethers, run, network } = require("hardhat")

async function main() {
    const SimpleStorageFactory = await ethers.getContractFactory(
        "SimpleStorage"
    )
    console.log("deploying contract")
    const simpleStorage = await SimpleStorageFactory.deploy()
    await simpleStorage.deployed()
    console.log(`contract deployed: ${simpleStorage.address}`)
    if (network.config.chainId === 4 && process.env.ETHERSCAN_VERICATION) {
        await simpleStorage.deployTransaction.wait(6)
        await verification(simpleStorage.address, [])
    }

    const AddingPerson = await simpleStorage.addPerson("jorge", 1000)
    await AddingPerson.wait(1)
    const ShowPerson = await simpleStorage.retrieveWithName("jorge")
    const ShowPersonA = await simpleStorage.returnObjectWithName("jorge")
    console.log(`el numero es ${ShowPerson}`)
    console.log(`el numero es ${ShowPersonA}`)
}

async function verification(contractAddress, arg) {
    console.log("verication contract...")
    try {
        await run("verify: verify", {
            address: contractAddress,
            constructorArguments: arg,
        })
    } catch (e) {
        if (e.message.toLowerCase().includes("already verified")) {
            console.log("already verified!!")
        } else {
            console.log(e)
        }
    }
}

main()

@jorgect207 verify:verify do not add space between these, hardhat is not recognizing it.

Problem lies here:

async function verification(contractAddress, arg) {
    console.log("verication contract...")
    try {
        await run("verify: verify", {
            address: contractAddress,
            constructorArguments: arg,
        })
    } 

Specifically: await run("verify: verify", {

There should be no space above, ie await run("verify:verify", {
