cannot find artifact "Greeter"; No Contract deployed with name FundMe

[harshuo2]

I have deleted the Greeter.sol contract and done everything as per what Patrick asked us to do. But when I run yarn hardhat test, I've been getting this error. When I tried to see where am I getting the "No Artifact found" error from, I saw that I have a deploy.js in my scripts folder. Do I need to tend to it as Patrick hasn't asked us to make any changes to it.
And as for the second No Contract FundMe found, I have no clue why I'm getting that error. Can someone please guide me?

(P.S. sorry for the bad formatting. Don't know how to end the ``` command. Guide me for that too please?)

Hey regarding your first error "I getting the "No Artifact found" error" :
It seems that there is sample-test.js in you test folder please delete sample-test.js because yarn hardhat test runs all the tests in the all the files.

For the Second question please check your deploy script from Patricks GitHub repo it seems FundMe this contract is not deploying correctly
For the third question regarding formatting you need to put ``` this both should be on two separate lines don't merge them in your code lines :

```javascript const a;```` this wont work since all are in the same line.

you need to break this in 3 line. first line(backticks and language name continous) and last line will be of only backticks and between first and last line there will be your code

[harshuo2]

but when I say yarn hardhat deploy, it deploys my code without any problems...

[technophile-04]

Have you deleted the sample-test.js? And could you share the error and you folder structure image please

[harshuo2]

I did it, brother. I found an error. I had trouble deploying it to a testnet. I will then try to run my tests. But nevertheless, shouldn't it work fine with hardhat or localhost? And should throw an error code in the staging tests?

[harshuo2]

I have realised that the error is coming because my FundMe contract is not being able to deploy. So I have attached my 01-deploy-fund-me.js file here. What do you think went wrong?

const { deployContract } = require("ethereum-waffle")
const {
  networkConfig,
  DEVELOPMENT_CHAINS,
} = require("../helper-hardhat-config")
require("dotenv").config()
const { verify } = require("../utils/verify")

module.exports = async ({ getNamedAccounts, deployments }) => {
  const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY
  console.log("Are we starting?")
  const { deploy, log } = deployments
  const { deployer } = await getNamedAccounts() 
  const chainId = network.config.chainId
  log(chainId)
  let EthUsdPriceFeedAddress
  if (DEVELOPMENT_CHAINS.includes(network.name)) {
    const EthUsdPriceFeedAggregator = await deployments.get("MockV3Aggregator")
    log(EthUsdPriceFeedAggregator)
    EthUsdPriceFeedAddress = EthUsdPriceFeedAggregator.address 
    log("reading local network")
  } else {
    log("Are we in here")
    EthUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
  }
  const args = [EthUsdPriceFeedAddress]
  log(args)
  log(network.name)
  log(deployer)
  const fundMe = await deploy("FundMe", {
    from: deployer,
    args: args, 
    log: true, 
    waitConfirmations: network.config.blockConfirmations || 1,
  })
  if (!DEVELOPMENT_CHAINS.includes(network.name) && ETHERSCAN_API_KEY) {
    await verify(fundMe.address, args)
  }
  log("----------------------------------------------------------")
}

module.exports.tag = ["all", "fundme"]

I have something similar. I added contract: 'FundMe', and it seemed to work. The reason I added it was because Patrick had it in the 00-deploy-mocks.js file.

Sorry for all of the edits. I just kept working on it and now it seems to also work on rinkeby (which it wasn't before). Here's my final code. Hope it helps..

const { network, deployments, getNamedAccounts } = require('hardhat')
const { networkConfig } = require('../helper-hardhat-config')
const { verify } = require('../utils/verify')

module.exports = async ({ getNamedAccounts, deployments }) => {
	const { deploy, log } = deployments
	const { deployer } = await getNamedAccounts()
	const chainId = network.config.chainId
	console.log(`chainId: ${chainId}`)

	let ethUsdPriceFeedAddress
	if (chainId == 31337) {
		const ethUsdAggregator = await deployments.get('MockV3Aggregator')
		ethUsdPriceFeedAddress = ethUsdAggregator.address //provides address from local chain
		console.log(`IF: ethUsdPriceFeedAddress: ${ethUsdPriceFeedAddress}`)
	} else {
		ethUsdPriceFeedAddress = networkConfig[chainId]['ethUsdPriceFeed'] //gets from actual chains
		console.log(`ELSE: ethUsdPriceFeedAddress: ${ethUsdPriceFeedAddress}`)
	}
	log('---------------------------------------------')
	log('Deploying FundMe. Waiting for confirmations...')
	const fundMe = await deploy('FundMe', {
		contract: 'FundeMe',
		from: deployer,
		args: [ethUsdPriceFeedAddress], //input for the solidity file
		log: true,
		waitConfirmations: network.config.blockConfirmations || 1,
	})
	log(`FundMe deployed at ${fundMe.address}`)
	if (chainId != 31337 && process.env.ETHERSCAN_API) {
		log('Verifying...')
		await verify(fundMe.address, ethUsdPriceFeedAddress)
		log('Verified')
		log('---------------------------------------')
	}
}
module.exports.tags = ['all', 'fundMe']

I also made sure to update my hardhat.config.js file since in rinkeby I had set the named accounts 4: 1 for the deployer. Changed to 4: 0. That might have helped on that side of things.

@harshuo2

you are missing a require statement in your 01-deploy-fund-me.js file that is needed to access getNamedAccounts, deployments, and network.

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

Make a repo, I will look into it.
