ISSUE IN CHAP-7 UNIT TESTING CODE

[soumalya340]

Hey the code is
describe("fund", async function () { it("updated the amount funded data structure", async function () { await fundMe.fund({ value: SendValue }) console.log(SendValue) const response = await fundMe.s_addressToAmountFunded(deployer) assert.equal(response.toString(), SendValue.toString()) }) })

when I'm doing yarn hardhat test --grep "amount funded" as shown in video I'm getting error
invalid address or ENS name (argument="name", value=undefined, code=INVALID_ARGUMENT, version=contracts/5.7.0)
Someone pls guide me asap bcz struck for hours here

Please share your entire code. Push it to github and leave a link here

https://github.com/soumalya340/ERROR/blob/main/FundMe.test.js , this is the code,
And I investigated the console.log and the fault is in the deployer; it displays undefined after deployment.Guide me what to do now

@soumalya340 push your entire code not just the FundMe.test.js file. I want to run all of it locally to see where the problem is.

@soumalya340 Make sure you have named accounts in the hardhat file

namedAccounts: {
  deployer: {
    default: 0,
  },
  player: {
    default: 1,
  },
},

Also, the deployer is gotten like this:

deployer = (await getNamedAccounts()).deployer;

And getNamedAccounts is coming from hardhat:

const { network, getNamedAccounts, deployments, ethers } = require("hardhat");

[alymurtazamemon]

@soumalya340 I saw your code, remove this const in front of it const deployer = (await getNamedAccounts()).deployer

[alymurtazamemon]

@soumalya340 we have available it to whole file.

The problem is,

 let fundMe
    let deployer
    let mockV3Aggregator
    var Address
    const SendValue = ethers.utils.parseEther("1") //helps to convert to ethers
    beforeEach(async function () {
        //deploy our fundme contract
        //using Hardhat - deploy

        // const accounts = await ethers.getSigners()
        const deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await ethers.getContract("FundMe", deployer)
        mockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })

here you declare the deployer 2 times on with this line let deployer and later here const deployer = (await getNamedAccounts()).deployer and this is the reason the test is failing.
Just remove the const keyword from this line, and that should work.
