Lesson 9 (15:19:57): cannot find artifact

[dgbweb3]

My repo: https://github.com/dgbweb3/hardhat-smartcontract-lottery

At the timestamp(15:19:57) I run:
yarn hardhat deploy

Then I return this error:

Error: ERROR processing /home/dgbweb3/hh-fcc/hardhat-smartcontract-lottery/deploy/00-deploy-mocks.js:
Error: cannot find artifact "VRFCoordinatorV2Mock"
at getArtifact (/home/dgbweb3/hh-fcc/hardhat-smartcontract-lottery/node_modules/hardhat-deploy/src/DeploymentsManager.ts:207:17)

00-deploy.mocks.js

const { developmentChains } = require("../helper-hardhat-config")

const BASE_FEE = ethers.utils.parseEther("0.25") //0.25 is the LINK premium per request
const GAS_PRICE_LINK = 1e9 //calculated value

module.exports = async function ({ getNamedAccounts, deployments }) {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const args = [BASE_FEE, GAS_PRICE_LINK]

    if (developmentChains.includes(network.name)) {
        log("Local Network Detected! Deploying mocks...")
        await deploy("VRFCoordinatorV2Mock", {
            from: deployer,
            log: true,
            args: args,
        })
        log("Mocks Deployed!")
        log("------------------------------")
    }
}

module.exports.tags = ["all", "mocks"]

I also noticed I am compiling a "cache" folder but not an "artifacts" folder...

Try to clean first npx/yarn hardhat clean and then compile npx/yarn hardhat compile

[TradMod]

I'm not sure its npx hardhat clean or npx hardhat clear, I think it's clean but pls make sure to double-check it

[dgbweb3]

Thanks for the response. I tried yarn hardhat clean and re-compiled then re-deployed. Same error :(

The compiled artifacts will be saved in the artifacts/ directory by default, or whatever your configured artifacts path is. Look at the paths configuration section to learn how to change it. This directory will be created if it doesn't exist. Let me know if this helps.

[krakxn]

Please merge that one - I have one more PR to be made after the changes.

[krakxn]

Implemented some fixes - do not know if they will fix the artifacts part but they get the logic of the code right, fixed the verify contract path, the order precedence of the arguments was incorrect in comparison to the constructor, as well as incorporating arguments in the Raffle contract to be deployed.

[dgbweb3]

I merged and updated both fixes and I am still getting the same error.

[krakxn]

I see, that is sad :(. They should fix the logical errors though. It seems you have tried various ways to clean the artifacts and cache too.

[dgbweb3]

I don't get artifacts when I compile. Which makes no sense. Worked fine on every project before. Maybe I should start a new hardhat project.

[alymurtazamemon]

@dgbweb3 Remove artifacts and cache folders if exist and recompile your contracts.

[alymurtazamemon]

@dgbweb3 But still after compiling it, while I deploy it to localhost it has other errors, you should doing all things again yourself and verify all things.

[dgbweb3]

I wiped out everything and pulled in the project fresh. Same error.

[dgbweb3]

Started a new project. Recompiled. Same error

[dgbweb3]

I started a third new project with @PatrickAlphaC repo and it worked. Just going to continue from there. Thank you so much @ali-thegilfoyle for taking so much time to help.

@dgbweb3 Best of Luck!
