Error: No deployment found for: FundMe

I think there is a problem with hardhat-deploy functions.

This error that keeps on showing when I use yarn hardhat test

FundMe
    constructor
      1) "before each" hook for "sets the aggregator addresses corrrectly"

Below is my FundMe.test.js

const { deployments, getNamedAccounts } = require("hardhat")
const { assert } = require("chai")

describe("FundMe", () => {
    let fundMe
    let MockV3Aggregator
    let deployer
    beforeEach(async () => {
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        fundMe = await deployments.get("FundMe", deployer)
        MockV3Aggregator = await deployments.get("MockV3Aggregator", deployer)
    })
    describe("constructor", () => {
        it("sets the aggregator addresses corrrectly", async () => {
            const response = await fundMe.priceFeed()
            assert.equal(response, MockV3Aggregator.target)
        })
    })
})

Below is my deploymocks.js

const { network } = require("hardhat")
const {
    developmentConfig,
    DECIMALS,
    INITIAL_PRICE,
} = require("../helper-hardhat-config")

module.exports.tags = ["all", "fundme"]
module.exports.default = deployFunc

My deployments folder has 2 subfolders: localhost and sepolia. I changed the name from localhost to hardhat because it was giving me errors for verifying otherwise.

Hi @eik-1

Instead of below:

fundMe = await deployments.get("FundMe", deployer)
MockV3Aggregator = await deployments.get("MockV3Aggregator", deployer)

try using this:

fundMe = await ethers.getContract("FundMe", deployer)
mockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer)
