Error: Transaction reverted: function call to a non-contract account

[ProKing13]

I have problem with the last unit test for fund:
Below is all My code snippet:

This is fund function from solidity file:

  function fund() public payable {
        require(
            PriceConverter.getConverstionRate(msg.value, priceFeed) >=
                minimumUsd,
            "Didn't send Enough"
        ); 
        funders.push(msg.sender);
        AdddressToAmountFunded[msg.sender] += msg.value;
    }

const { assert, expect } = require("chai")
const { ethers, getNamedAccounts, deployments } = require("hardhat")
require("hardhat-deploy-ethers") // adding this so nessesary for getContract function

describe("FundMe", () => {
  let fundMe
  let deployer
  let mockV3Aggregator
  // const sendValue=1000000000000000
//const sendValue=ethers.utils.parseEther("1")// this gives error because this is changed in version6 of ethers as below line
const sendValue = ethers.parseEther("1")//now this line correct

  beforeEach(async () => {
    // await contract.deploymentTransaction().wait(1)

    deployer = (await getNamedAccounts()).deployer
    await deployments.fixture(["all"])
    fundMe = await ethers.getContract("FundMe", deployer)
    //   await fundMe.deploymentTransaction().wait(1)
    mockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer)
    // console.log("this is mockV3Aggregator: ")
    // console.log(mockV3Aggregator)
  })
  describe("constructor", () => {
    it("sets the aggregator address correctly", async () => {
      const response = await fundMe.priceFeed()
      //   console.log("this is response address : "+response)
      assert.equal(response, await mockV3Aggregator.getAddress()) // mockV3aggregator.address is not used
    })
  })
  describe("fund", () => {
    it("Fail if you do  not send enough ETH", async () => {
      await expect(fundMe.fund()).to.be.reverted
    })
    it("updated the amount funded data structure", async () => {
      console.log("Hello")
  
console.log("Afghanistan")
        await fundMe.fund({ value: sendValue })
      console.log("hi")
      const response = await fundMe.AdddressToAmountFunded(deployer)
      console.log(response)
      assert.equal(response.toString(), sendValue.toString())
    })
  })
})

Problem is in below part:

it("updated the amount funded data structure", async () => {
      console.log("Hello")
  const sendValue = ethers.parseEther("1")
console.log("Afghanistan")
        await fundMe.fund({ value: sendValue })
      console.log("hi")
      const response = await fundMe.AdddressToAmountFunded(deployer)
      console.log(response)
      assert.equal(response.toString(), sendValue.toString())
    })

Plz help to solve this

FundMe
    constructor
      ✔ sets the aggregator address correctly
    fund
      ✔ Fail if you do  not send enough ETH
Hello
Afghanistan

      1) updated the amount funded data structure


  2 passing (5s)
  1 failing

  1) FundMe
       fund
         updated the amount funded data structure:

Hi @MohammadArif13

This error means you are trying to call contract that doesnt exist. So it is probably issue with PriceConverter contract

[ProKing13]

Bro PriceConverter is a library:

// SPDX-License-Identifier: MIT
pragma solidity 0.8.7;
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

library PriceConverter {
    function getPrice(AggregatorV3Interface priceFeed) internal view returns (uint256) {
      
        (, int256 price, , , ) = priceFeed.latestRoundData();
        return uint256(price * 1e10);
    }
  
    function getConverstionRate(
        uint256 ethAmount,AggregatorV3Interface priceFeed
    ) internal view returns (uint256) {
        uint256 ethPrice = getPrice(priceFeed);
        uint256 ethAmountInUsd = (ethPrice * ethAmount) / 1e18;
        return ethAmountInUsd;
    }
}

Hi @MohammadArif13

Indeed it is, but you did not post your github repo for this issue, so I'm only guessing. The problem might be you did not include that PriceConverter or you are just passing incorrect adresses in your tests
