Error: No Contract deployed with name FundMe

[Crawlling]

Hi,In lesson 7:https://youtu.be/gyMwXuJrbJQ?t=40609. I've try everything, but still got this.

Here is code:
const { deployments, ethers, getNamedAccounts } = require("hardhat")
const { assert } = require("chai")

describe("FundMe", async function () {
let fundme
let deployer
let MockV3Aggregator

beforeEach(async () => {
deployer = (await getNamedAccounts()).deployer
await deployments.fixture(["all"])
fundme = await ethers.getContract("FundMe", deployer)
MockV3Aggregator = await ethers.getContract(
"MockV3Aggregator",
deployer
)
})

describe("constructor", async function () {
it("set the aggregator addresses correctly", async function () {
const response = await fundme.priceFeed()

    assert.equal(response, MockV3Aggregator.address)
})

})
})

Here is error:

got this,I use module.exports.default instead of module.exports then everything ok.

I am also facing the same issue. Adding module.exports.default did not solve the issue for me
