Please help I am getting this Error: call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="balanceOf(address)", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.7.0) while running scripts

aaveBorrow,js file

const { getNamedAccounts, ethers } = require("hardhat")
const { getWeth } = require("../scripts/getWETH.js")

async function main() {
    //the protocol treats everything as an ERC20 token
    await getWeth()
    const { deployer } = await getNamedAccounts()
    const lendingPool = await getLendingPool(deployer)
    console.log(`LendingPool address ${lendingPool.address}`)

    const wethTokenAddress = "Address"
}

async function getLendingPool(account) {
    const lendingPoolAddressProvider = await ethers.getContractAt(
        "ILendingPoolAddressesProvider",
        "Address",
        account
    )
    const lendingPoolAdress = await lendingPoolAddressesProvider.getLendingPool()
    const lendingPool = await ethers.getContractAt("ILendingPool", lendingPoolAdress, account)
    return lendingPool
}
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

getWeth.js

const { getNamedAccounts, ethers } = require("hardhat")
const AMOUNT = ethers.utils.parseEther("0.1")

async function getWeth() {
    const { deployer } = await getNamedAccounts()
    //call the deposit function on weth contract
    //abi✅,contract address✅
    const iWeth = await ethers.getContractAt(
        "IWeth",
        "address",
        deployer
    )
    const tx = await iWeth.deposit({ value: AMOUNT })
    await tx.wait(1)
    const wethBalance = await iWeth.balanceOf(deployer)
    console.log(`Got ${wethBalance.toString()} WETH`)
}

module.exports = { getWeth, AMOUNT }

I have written the same code as shown in the tutorial please help

@highHumann Make sure the deployer address is not empty/undefined

[highHumann]

it is not undefined/empty

[alymurtazamemon]

@highHumann Please leave your repository link if you still do not find the answer.

@highHumann
address is incorrect I think

const iWeth = await ethers.getContractAt(
        "IWeth",
        "address", <----- remove this and put the actual address and then try
        deployer
    )

this is the address for weth on mainnet -> 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2

[aaankeet]

it should look like this

const iWeth = await ethers.getContractAt(
        "IWeth", // abi
        "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // contract address
        deployer // connected address
    )

[highHumann]

thanks for replying I have used the same format you have shown and fill the contract address with the real address

[aaankeet]

@highHumann so did it work?

[highHumann]

no it isn't working
