[TimeKeyRoll]

Hi, I am getting this error while testing 'getContract' function does not exist did anyone has experience this? Kindly help

fundme.test

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

describe("FundMe", async function () {
    let fundMe
    let deployer
    let mockV3Aggregator
    beforeEach(async function () {
        //const {deployer}= await.getNamedAccounts()
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture("all")
        fundMe = await ethers.getContractAt("FundMe", deployer)
        mockV3Aggregator = await ethers.getContractAt(
            "MockV3Aggregator",
            deployer
        )
    })

    describe("constructor", async function () {
        it("sets the right address for aggregator", async function () {
            const response = await fundMe.priceFeed()
            assert.equal(response, mockV3Aggregator.address)
        })
    })
})

@MasterofBlockchain Push to GitHub and leave a link here I need to test it locally.

[TimeKeyRoll]

I have still not learnt GIthub push. sorry.

but if you could help me to push? or can i copy paste things here?

[alymurtazamemon]

@MasterofBlockchain Great! it is the best time to learn it. Here is a link: LINK

[TimeKeyRoll]

Okay cool. Thank you

here is the link brother and a picture with an error which has kept me stuck.

@MasterofBlockchain Reply w/ the FundMe contract

[krakxn]

GitHub site, click on create a repo, pick a suitable name and remove any ticks on License, .gitignore etc.

Now, in your IDE (ie, the local directory where you have this lesson's files) be on the correct path. Now, do the following seperately:

Note: On GitHub, click on your repo and copy the HTTPS link of your repo, and paste it instead of the www.sample_link

 git init -b main
 git add .
 git commit -m "init commit"
 git remote add origin www.sample_link
 git push origin main

[TimeKeyRoll]

I am stuck with last step

[krakxn]

Are you certain you followed properly? As this arises from an incorrect branch creation.

[TimeKeyRoll]

Yes showed you the error..

Hey @MasterofBlockchain make these corrections:

1. await deployments.fixture("all") should be await deployments.fixture(["all"])
2. make sure to use getContract instead of getContractAt in these two lines.

        fundMe = await ethers.getContractAt("FundMe", deployer)
        mockV3Aggregator = await ethers.getContractAt(
            "MockV3Aggregator",
            deployer
        )

[TimeKeyRoll]

YES have downloaded the @nomiclabs/hardhat-waffle but got this error now.

[othaime-en]

go to https://hardhat.org/hardhat-chai-matchers/docs/migrate-from-waffle and follow the steps outlined there.

In the meantime, you need to find a way to push your code to github. Makes it easy to know the problem if we have all your code.

[TimeKeyRoll]

Well, changes have been made. I swtiched it to chai matchers. but there is now another error and contract eror is gone.lol And i am learning the way to push it to Github. :)

[othaime-en]

Notify me when you've pushed the code to github. The link I shared above is an easy an straightforward way to learn how to push.

Please check and let me know if i pushed it write? And please let me know what's the mistake? So i could change rather than someone else changing it for me.. because i don't want to get lost. thankyou again.

[Muhammad-Abdullah012]

Hey @MasterofBlockchain Reply with your package.json file

[Muhammad-Abdullah012]

@MasterofBlockchain
Try this...

        fundMe = await ethers.getContract("FundMe", deployer)
        mockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )

[TimeKeyRoll]

I have the same script right there. Nothing happened.

[Muhammad-Abdullah012]

What is exact error message with above script??

[Muhammad-Abdullah012]

@MasterofBlockchain

I have the same script right there. Nothing happened.

You are using ethers.getContractAt, use ethers.getContract

[TimeKeyRoll]

Yes I tried changing

[Muhammad-Abdullah012]

@MasterofBlockchain Made a pull request, merge and pull changes, this will fix all your issues.

[Muhammad-Abdullah012]

@MasterofBlockchain I've done it right now, It is running successfully. I've screen recorded the whole process...

[TimeKeyRoll]

just right now i tried

[Muhammad-Abdullah012]

create another folder..
Clone your repo in that...
Then follow steps

[TimeKeyRoll]

This is truly beautiful. And I tried cloning and followed and got the error lol

I guess I have found the error.. Npm install ain't working in cmd.

[TimeKeyRoll]

Yes I fixed the npm and it fixed everything. Lol

[othaime-en]

Hey @MasterofBlockchain I've looked into your code and there seems to be a problem with your dependencies. run yarn add --dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers

Also don't forget to replace getContractAt() with getContract() in your fundme.test.js file

[TimeKeyRoll]

Yes bro. It's randomly taking time. Don't know what's wrong. I will keep on trying and tag you once I'm done.

[TimeKeyRoll]

I'm totally struggling to push it to git hub. It is just moving and moving and taking forever.

I will surely let you know when it's there.

Buy I was wondering if 'hardhat-toolbox' comes with most of the dependencies which I have mentioned earlier but it does not have 'waffle' .. So I'm trying to install 'waffle' so all dependencies will be completed but it won't download.. If you could check error..

Or if you want to wait until I push it. I'm fine with that too.

[TimeKeyRoll]

[othaime-en]

You didn't have to install hardhat-waffle you already had hardhat-chai-matchers those are conflicting dependencies you can't have both. The list I gave you was okay. You didn't have to remove or add anything. All you had to do was copy paste and run one command. npm install That's it.
Having extra dependencies in your package.json that you don't use have no effect on your project so you didn't have to worry about anything that you thought you wouldn't need.

[TimeKeyRoll]

Perfect. I have updated the repo just by now.. Using others and Google knowledge and error won't go and make me wanna kill me.
Please have a look when you can.

[othaime-en]

Hey. @MasterofBlockchain as it is right now (including the latest commit), I fixed everything with the command

npm install --save-dev  @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers

same command I told you yesternight.

[TimeKeyRoll]

Yes please

[othaime-en]

Yes it works.

[TimeKeyRoll]

I think I have also figured it. My npm has an error which is not making me run any command and giving me an error

[TimeKeyRoll]

Need to fix this npm error.. Before there is this other guy who screen recored the process for me. And i figured npm problem

[othaime-en]

I'm using npm 8.
Try and fix it because everything works perfectly. I've run the test 5 times and its working

[TimeKeyRoll]

@Muhammad-Abdullah012

@othaime-en

Thank you very much for helping me and being patience with me. The problem was with npm. And it's fixed and it has fixed the code as well....
