getting error on testing

Error: could not decode result data (value="0x", info={ "method": "getPriceFeed", "signature": "getPriceFeed()" }, code=BAD_DATA, version=6.6.7)

HERE IS MY TEST.JS

`
const { deployments, ethers, getNamedAccounts } = require("hardhat")
const { assert } = require("chai")
//const { deployer } = getNamedAccounts()
describe("FundMe", async function () {
//anonymous function
let fundMe
let deployer
let mockV3Aggregator

beforeEach(async function () {
    //this is created to first deploy our contract
    //using hardhat funme deploy
    deployer = (await getNamedAccounts()).deployer
    await deployments.fixture(["all"]) // it helps to deploy all contract and scripts in one go on local host
    fundMe = await ethers.getContractAt("FundMe", deployer) //get most recent deployed contract wrapped with hardhar ethers
    mockV3Aggregator = await ethers.getContractAt(
        "MockV3Aggregator",
        deployer
    )
})

describe("constructor", async function () {
    it("sets the aggregator addresses correctly", async () => {
        const response = await fundMe.priceFeed()
        assert.equal(response, mockV3Aggregator.target)
    })
}) 

})

Try downgrading your ethers version to "ethers": "^5.5.3".

Glad I could help. Please mark my message as answer, so people with similar issue can find it easier :)

[vishnu-geek]

definitely i could but downgrading ethers doesnot make sense

[Nlferu]

Then pass your solution and mark it as answer or just close discussion :)

[vishnu-geek]

thanks for the help buddy i first deployed on test net and suprisingly after that all test passed

@vishnu-geek

Just for your information downgrading ethers make total sense here as calling different functions/getters etc. drastically changes between ether 5 and ethers 6. In course we are using ethers 5 and you are using ethers 6 :)
