Lending Pool Address Undefined

[Noveleader]

Hey everyone, I started by using aave V3 protocol, and then I moved the whole system to V2 but still I am getting the same error.

I have installed both aave V2 protocol and V3 but it doesn't seem to have any effect. I anyone could help!

aaveBorrow.js

const { getNamedAccounts, ethers } = require("hardhat")
const { getWeth } = require("../scripts/getWeth")
async function main() {
  //The protocol treats everything as an ERC20 token - the WETH
  await getWeth()
  const { deployer } = await getNamedAccounts()
  //To interact with aave protocol, what do we need?
  //ABI, contract address
  //POOL ADDRESS PROVIDER V3 : 0x2f39d218133AFaB8F2B819B1066c7E434Ad94E9e
  //POOL ADDRESS PROVIDER V2 : 0xB53C1a33016B2DC2fF3653530bfF1848a515c8c5
  const pool = getPool(deployer)
  console.log(`Pool Address ${pool.address}`)
}
async function getPool(account) {
  const poolAddressProvider = await ethers.getContractAt(
    "ILendingPoolAddressesProvider",
    "0xB53C1a33016B2DC2fF3653530bfF1848a515c8c5",
    account
  )
  const poolAddress = await poolAddressProvider.getLendingPool()
  const pool = await ethers.getContractAt("ILendingPool", poolAddress, account)
  return pool
}

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

    ],
  },
  mocha: {

}

The contracts are imported correctly, there's no issue with that.

Hello @Noveleader

You are just missing await in below line:

const pool = await getPool(deployer)

Ohhh, only this was the issue. Thanks mate, just deployed. It deploys correctly.
