Lesson 14 02-deploy error

[bbl4de]

I'm currently trying to deploy randomipfsnft with a command:

yarn hardhat deploy --tags randomipfs,mocks

When I run it I get this error:

yarn run v1.22.19
warning package.json: No license field
$ /root/hardhat-nft-hh/node_modules/.bin/hardhat deploy --tags randomipfs,mocks
Nothing to compile

I was unable to solve it by myself. I know that it's something with the VRFCoordinatorV2Mock, but I think it's deploying correctly, so I don't know why 02-deploy doesn't work.

Here is my 02-deploy-random-ipfs-nft.js:

const { ethers, network, deployments } = require('hardhat')
const { networkConfig, developmentChains } = require('../helper-hardhat-config')
const { verify } = require('../utils/verify')
const {
  storeImages,
  storeTokenUriMetadata,
} = require('../utils/uploadToPinata')

const imagesLocation = './images/randomNft'

module.exports = async function ({ getNamedAccounts, deployments }) {
  const { deploy, log } = deployments
  const { deployer } = await getNamedAccounts()
  const chainId = network.config.chainId

  // get ipfs hashes of our images
  // with our own IPFS node
  // or use Pinata
  // or use nft storage (that uses filecoin)
  if (process.env.UPLOAD_TO_PINATA == 'true') {
    tokenUris = await handleTokenUris()
  }

  let vrfCoordinatorV2Address, subscriptionId, vrfCoordinatorV2Mock

  if (developmentChains.includes(network.name)) {
    const vrfCoordinatorV2Mock = await ethers.getContract(
      'VRFCoordinatorV2Mock',
    )
    vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
    const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
    const transactionReceipt = await transactionResponse.wait()
    subscriptionId = transactionReceipt.events[0].args.subId
    subscriptionId = txReceipt.events[0].args.subId
  } else {
    vrfCoordinatorV2Address = networkConfig[chainId].vrfCoordinatorV2
    subscriptionId = networkConfig[chainId].subscriptionId
  }

  log('--------------------')
  await storeImages(imagesLocation)
  //   const args = [
  //     vrfCoordinatorV2Address,
  //     subscriptionId,
  //     networkConfig[chainId].gasLane,
  //     networkConfig[chainId].callbackGasLimit,
  //     networkConfig[chainId].mintFee,
  //   ]
}

async function handleTokenUris() {
  tokenUris = []
  // store the Image in IPFS
  // store the metadata in IPFS

  return tokenUris
}

module.exports.tags = ['all', 'randomipfs', 'main']

Please let me know if repo is necessary.

You are using ethers v6, and in v6 the address member is replaced by target, and the below line is giving error.

vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address

I recommend you to remove the ethers folder from node modules and do

yarn add --dev ethers@5.7.2

With ethers v5.7.2, everything shown in the video will remain as it is, but there are certain changes done in v6.

try this command npm i --force
I think some packages didn't install well.
sometimes when using yarn some packages didn't install well for compatible reasons.

[shikhar229169]

Actually your ethers is still v6.
In v6 the address member is changed to target.
So I recommend you to go to ethers v5.7.2.
Ensure that you delete the ethers from node modules and then run,

yarn add --dev ethers@5.7.2

Thank you for responses, though it didn't work and I decided to past this section and continue the course. I tried many solutions from the internet as well and even created this project again by copying contracts, deployments scripts etc., but installing packages from scratch and still had same issue .

[bbl4de]

I managed to solve the issue. I had to change few things for anyone with the same issue. Firstly, to prevent all the compatibility issues I just downloaded the latest versions with:

yarn add --dev hardhat @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers

Then after searching for any informations about vrfCoordinatorV2Mock.address in the new ethers, I found out that the name has changed to

- vrfCoordinatorV2Mock.address
+ vrfCoordinatorV2Mock.target

But then, I got another error with subscriptionId being undefined, resulting in "no emitted events" issue. I found a discussion from lesson 9 error and solved it by writing;

- subscriptionId = transactionReceipt.events[0].args.subId
+ subscriptionId = 1

It was really annoying, tough I learned a lot about different ethers versions.

[shikhar229169]

Yeah it's really frustrating about the versions and the compatibility issues.
I was using a package.json file in every project and it was working perfectly fine. But from yesterday idk what happened, the packages started having compatibility issues with each other.

Then I went to discussions and found a similar issue with that and finally I get the packages which are now working fine.

You can go to my GitHub profile and check the repo with name hardhat package ethers, there I have uploaded the package.json file and the hardhat.config.js file and they are working perfectly fine for now.

Thanks I will check it out, because now I have similar issues with 04-mint.js deployment file...
