error Error: No Contract deployed with name FundMe

[abdullahAttiq]

@alymurtazamemon i am having same error, can you help me out too

const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { network, getNamedAccounts, deployments } = require("hardhat")
const { verify } = require("../utils/verify")
module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    let ethUsdPriceFeedAddress
    if (chainId == 31337) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    const args = [ethUsdPriceFeedAddress]

    const FundMe = await deploy("FundMe", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmation || 1,
    })

    log(`FundMe deployed at ${FundMe.address}`)

    if (!developmentChains.includes(network.name) && process.env.API_KEY) {
        await verify(FundMe.address, args)
    }
    {
        await verify(FundMe.address, [ethUsdPriceFeedAddress])
    }
}

module.exports.tags = ("all", "FundMe")

the above is 01-deploy-fund-me.js
and below is fundMe.test.js

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

describe("fundMe", async function () {
    let hello
    let deployer
    let MockV3Aggregator
    beforeEach(async function () {
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        hello = await ethers.getContract("FundMe", deployer)
        MockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })
    describe("constructor", async function () {
        it("sets the aggregator addresses correctly", async function () {
            const response = await hello.getPriceFeed()
            assert.equal(response, MockV3Aggregator.address)
        })
    })
})

the error is below:

Contract name looks fine to me.
Try deleting the artifacts and cache folder and compiling again.
Run yarn hardhat clean then yarn hardhat compile and see if it fixes your issue.

Push the code to github and leave a link here then

[alymurtazamemon]

@abdullahAttiq Push it to GitHub and leave link here.

[abdullahAttiq]

sorry for the delay guys....learning things along the way so it takes time sometime.....here's the link:

@abdullahAttiq

Problem lies in the deploy script for fundme, it should be this instead: module.exports.tags = ["all", "fundme"] with the [] and also, in snakecase.

[RoboCrypter]

@abdullahAttiq : ^ Exactly what @krakxn said: Your module.exports.tags in your deploy script is causing the error,
Convert it to : module.exports.tags = ["all", "fundme"]
From this: module.exports.tags = ("all", "FundMe")

Because your await deployments.fixture(["all"]) in your fundMe.test.js is not picking up any deployments... So, it is saying no Contract deployed with the name FundMe.

Hopefully, It will fix the issue!

[abdullahAttiq]

got it that's it....thanks very much guys you all are amazing.. @krakxn @abossofmyself @othaime-en @alymurtazamemon
