When i am trying to run the scripts , i am getting this error . I have deployed all the contracts but still getting the same error .

const {getWeth,AMOUNT} = require("./getWeth.js");
const {getNamedAccounts} = require("hardhat")

async function main(){
    await getWeth();
    const {deployer}= await getNamedAccounts();

    const lendingPool = await lendingpool(deployer);
    console.log(`Lending pool address: ${lendingPool.address}`);

    //deposit 
    const wethTokenAddress = "0xC02aaA3...";
    ///aprove
    await approveERC20(wethTokenAddress,lendingPool.address,AMOUNT , deployer);
    console.log('Depositing....');
    await lendingPool.deposit(wethTokenAddress,AMOUNT,deployer,0);
    console.log('Deposited!!!');
}

async function lendingpool(accounts){
    const lendingPoolAddressesProvider = await ethers.getContractAt("ILendingPoolAddressesProvider","0x88757f2f9...",accounts);
    const lendingPoolAddress = await lendingPoolAddressesProvider.getLendingPool();
    const lendingPool = await ethers.getContractAt("ILendingPool",lendingPoolAddress,accounts);
    return lendingPool;
}

async function approveERC20(erc20Address , spenderAddress , amountToSpend , account){
    const erc20Token = await ethers.getContractAt("IERC20",erc20Address,account);
    const tx = await erc20Token.approve(spenderAddress,amountToSpend);
    tx.wait(1);
    console.log('Token approved......!!');
}
main()
    .then(()=> process.exit(0))
    .catch((err)=>{
        console.log(err);
        process.exit(1);
    })

Hi @ImAnshuJoshi I see that you're using Hardhat and not Truffle, so at this point we're not able to help you.
