Lesson 6: Typescript problem

[TucanCrypto]

I complete alomst all lesson 6 (so I would like no change my package.json because if I change ethers v6 by ethers v5 this file executes but the rest no) except the last minute because I can't even execute my test-deploy.ts; because the following problem appears:

Conversion of type 'ContractFactory<[overrides?: (NonPayableOverrides & { from?: string | undefined; }) | undefined], Contract>' to type 'SimpleStorage__factory' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
  The types returned by 'deploy(...)' are incompatible between these types.
    Type 'Promise<BaseContract & { deploymentTransaction(): ContractTransactionResponse; } & Omit<Contract, keyof BaseContract>>' is not comparable to type 'Promise<SimpleStorage & { deploymentTransaction(): ContractTransactionResponse; }>'.
      Type 'BaseContract & { deploymentTransaction(): ContractTransactionResponse; } & Omit<Contract, keyof BaseContract>' is not comparable to type 'SimpleStorage & { deploymentTransaction(): ContractTransactionResponse; }'.
        Type 'BaseContract & { deploymentTransaction(): ContractTransactionResponse; } & Omit<Contract, keyof BaseContract>' is missing the following properties from type 'SimpleStorage': addPerson, nameToFavoriteNumber, people, retrieve, store

My test-deploy.ts look like:

import { ethers } from "hardhat"
import { expect, assert } from "chai"
import { SimpleStorage, SimpleStorage__factory } from "../typechain-types"

describe("SimpleStorage", function () {
    let simpleStorageFactory: SimpleStorage__factory
    let simpleStorage: SimpleStorage
    beforeEach(async function () {
        simpleStorageFactory = (await ethers.getContractFactory(
            "SimpleStorage"
        )) as SimpleStorage__factory
        simpleStorage = await simpleStorageFactory.deploy()
    })

    it("Should start with a favorite number of 0", async function () {
        const currentValue = await simpleStorage.retrieve()
        const expectedValue = "0"
        assert.equal(currentValue.toString(), expectedValue)
    })
    it("Should update when we call store", async function () {
        const expectedValue = "7"
        const transactionResponse = await simpleStorage.store("7")
        await transactionResponse.wait(1)

        const currentValue = await simpleStorage.retrieve()
        assert.equal(currentValue.toString(), expectedValue)
    })
})

My hardhat.config.ts is:

import "@nomicfoundation/hardhat-toolbox"
import "dotenv/config"
import "./tasks/block-number"
import "hardhat-gas-reporter"
import "solidity-coverage"
import "@nomiclabs/hardhat-ethers"
import "@typechain/hardhat"

/** @type import('hardhat/config').HardhatUserConfig */

const MUMBAI_RPC_URL = process.env.MUMBAI_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const MUMBAISCAN_API_KEY = process.env.MUMBAISCAN_API_KEY
const COINMARKETCAP_API_KEY = process.env.COINMARKETCAP_API_KEY

module.exports = {
    defaultNetwork: "hardhat",
    networks: {
        mumbai: {
            url: MUMBAI_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 80001,
        },
        localhost: {
            url: "http://127.0.0.1:8545/",
            chainId: 31337,
        },
    },
    solidity: "0.8.7",
    etherscan: {
        apiKey: MUMBAISCAN_API_KEY,
    },
    gasReporter: {
        enabled: false,
        outputFile: "gas-report.txt",
        noColors: true,
        currency: "USD",
        coinmarketcap: COINMARKETCAP_API_KEY,
        token: "MATIC",
    },
}

And my pacakage.json:

I changed my test-deploy.ts and now works:

import { ethers } from "hardhat"
import { expect, assert } from "chai"
import { SimpleStorage, SimpleStorage__factory } from "../typechain-types"

describe("SimpleStorage", function () {
    //let simpleStorageFactory: SimpleStorage__factory
    //let simpleStorage: SimpleStorage
    let simpleStorage: any

    beforeEach(async function () {
        const simpleStorageFactory = await ethers.getContractFactory(
            "SimpleStorage"
        )
        simpleStorage = await simpleStorageFactory.deploy()
        await simpleStorage.waitForDeployment()
    })

    it("Should start with a favorite number of 0", async function () {
        const currentValue = await simpleStorage.retrieve()
        const expectedValue = "0"
        assert.equal(currentValue.toString(), expectedValue)
    })
    it("Should update when we call store", async function () {
        const expectedValue = "7"
        const transactionResponse = await simpleStorage.store("7")
        await transactionResponse.wait(1)

        const currentValue = await simpleStorage.retrieve()
        assert.equal(currentValue.toString(), expectedValue)
    })
})
