LESSON 13, Error: invalid signer (argument="signer", value={"deployer":"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266"}, code=INVALID_ARGUMENT,

[Benrockiee]

When i try to run my aaveborrow script using yarn hardhat run scripts/aaveborrow.js

i get this error

    code=INVALID_ARGUMENT, version=contracts/5.7.0)
   at Logger.makeError (/home/solid-rugged/hardhat-defi-protocols/node_modules/@ethersproject/logger/src.ts/index.ts:269:28)
   at Logger.throwError (/home/solid-rugged/hardhat-defi-protocols/node_modules/@ethersproject/logger/src.ts/index.ts:281:20)

This is my aaveborrow script

const { getWeth, AMOUNT } = require("../scripts/getWeth.js")
const { networkConfig } = require("../helper-hardhat-config")

async function main() {
    await getWeth()
}

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

And this is my getWeth script

const { networkConfig } = require("../helper-hardhat-config")

const AMOUNT = ethers.utils.parseEther("0.02")

async function getWeth() {
    const deployer = await getNamedAccounts()
    const iWeth = await ethers.getContractAt(
        "IWeth",
        networkConfig[network.config.chainId].wethToken,
        deployer
    )

    //We deposit some amount
    const tx = await iWeth.deposit({ value: AMOUNT })
    //We wait...
    await tx.wait(1)
    //We get the balance
    const wethBalance = await iWeth.balanceOf(deployer)
    console.log(`Got ${wethBalance.toString()}WETH`)
}

module.exports = { getWeth, AMOUNT }

This is my helper hardhat config file from Repo..

@Benrockiee add --network localhost at the end of the command and make sure the hardhat node is running. Let me know if you still face issues.

[Benrockiee]

@alymurtazamemon I just added it bro

[alymurtazamemon]

@Benrockiee

-const deployer = await getNamedAccounts()
+const {deployer} = await getNamedAccounts()

[alymurtazamemon]

@Benrockiee add this as well const { getNamedAccounts, network, ethers } = require("hardhat");

[Benrockiee]

@alymurtazamemon Thanks bro, the deployer curly brackets thing worked..

Bro that site deployment issue i made earlier about not being able to deploy to fleek, i havent found an answer to it..

[alymurtazamemon]

@Benrockiee Let's discuss this in a separate discussion.

[othaime-en]

Hey @Benrockiee add this const { getNamedAccounts, ethers } = require("hardhat") in your getWeth script and replace const deployer = await getNamedAccounts() with const {deployer} = await getNamedAccounts()

[Benrockiee]

Thanks bro

I am also facing same problem but after trying the above solution i still can't solve the problem please can someone help me . I used the same code available above but getting this error
error invalid signer (argument="signer", value="0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266", code=INVALID_ARGUMENT, version=contracts/5.7.0)

It is expecting a signer object.

1.First connect to the local hardhat blockchain. Keep your hardhat node running .

const provider = new ethers.providers.JsonRpcProvider(
    "http://127.0.0.1:8545/"
  );

2. Get the signer object by requesting from the provider.
   const signer = await provider.getSigner();

3. Now use this signer object instead of deployer. Like this

const iWeth = await ethers.getContractAt(
    "IWeth",
    networkConfig[network.config.chainId].wethToken,
    signer
  );
