Describe the bug

At the unit testing section on course Lesson7 around 11：23 (https://youtu.be/gyMwXuJrbJQ?t=41004) around 11:20 failed the test "updated the amount funded data structure". Seems like sendValue failed but I declared the sendValue for 1 Ether and pass the args of sendvalue.

Error Information

FundMe
fund
updated the amount funded data structure:

at FundMe.fund (contracts/FundMe.sol:40)

test script - fundme.test.js

const sendValue = ethers.utils.parseEther("1")

describe("fund", async function () {
    it("Fails if you don't send enough ETH", async function () {
        await expect(fundMe.fund()).to.be.revertedWith(
            "You need to spend more ETH!"
        )
    })

    it("updated the amount funded data structure", async function () {
        // 执行fund，获取funder的地址=>金额映射，和fund的金额做对比
        await fundMe.fund({ value: sendValue })
        const response = await fundMe.addressToAmountFunded(deployer)
        assert.equal(response.toString(), sendValue.toString())
    })
