I have looked into similar issues for references before creating this post, but it didn't solved the issue.

If anyone can help me with this, it would be greatly appreciated. Thank you!

Hello @Jatinkkalra

In your deploy script just change below:

From:

module.exports.tags = ["all, fundMe"];

Into:

module.exports.tags = ["all", "fundMe"];

##Update:

I have modified the code a bit so that I can try to find which line is causing the issue:

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

describe("FundMeWithLibrary", function () {
  let fundMe;
  let deployer;
  let mockV3Aggregator;
  beforeEach(async function () {
    // Deploy our fundMeWithLibrary contract using hardhat-deploy

    // const { deployer } = await getNamedAccounts();
    // Another way to get deployer while assigning to a variable:
    deployer = (await getNamedAccounts()).deployer;
    await console.log("1!!");
    await deployments.fixture(["all"]); // .fixture() for reuse of duplicate code in deployment
    await console.log("2!!");
    fundMe = await ethers.getContract("FundMeWithLibrary", deployer);
    await console.log("3!!");
    mockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer);
    await console.log("4!!");
  });
  describe("constructor", async function () {
    it("Sets the aggregator addresses correctly", async function () {
      const response = await fundMe.priceFeed;
      assert.equal(response, mockV3Aggregator.address);
    });
  });
});

Error response:

Based on the error response, looks like error is on this line:

    fundMe = await ethers.getContract("FundMeWithLibrary", deployer);

I am not sure what it could be though.

Hello @Jatinkkalra

I have managed to fix your problem. First of all you have to move below line in your 01-deploy-fund-me out of module.exports = async ... {}:

module.exports.tags = ["all", "fundMe"] // It has to be outside code at the end

Wrong:

Correct:

Then in your FundMeWithLibrary.sol you have to add getter for priceFeed like below:

    function getPriceFeed() public view returns (AggregatorV3Interface) {
        return priceFeed;
    }

And at last in your FundMe.test.js you have to modify below line like this:

// Wrong !!!
const response = await fundMe.priceFeed

// Correct
const response = await fundMe.getPriceFeed()

Or you can just call below without adding getPriceFeed():

const response = await fundMe.priceFeed()

This worked! Thank You @Neftyr !

May I also please confirm if you used a specific tool or something to debug this code? 🙏

Hi @Jatinkkalra

Nah I have just cloned your repository and used basic logic to fix code. If it was throwing error that no contract with name.. was deployed i knew there is something wrong with either fixture or deploy script ;) Rest was even easier to spot. I'm glad I could help :)

[Jatinkkalra]

Good to know and thank you. I got stuck for too long on this.
A silly mistake but I am still learning.

Once again, appreciate the help! 🙌
