Debugging FundMe.sol

[COSMICnoob80]

I have been trying but I am still not able to debug the following contract:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.8;

error NotOwner();

contract FundMe {
address public owner;

address[] public funders;

uint256 public MINIMUM_USD = 50 * 10 ** 18;

mapping (address => uint256) public addressToAmountFunded;

constructor () {

owner = msg.sender;

}

function fund() public payable {

require(msg.value.getConversionRate() >= MINIMUM_USD, "YOU NEED TO SEND MORE eth!");

addressToAmountFunded[msg.sender] += msg.value;
funders.push(msg.sender);

}

modifier onlyOwner {
if(msg.sender != owner) revert NotOwner();

_;
}

function withdraw () public onlyOwner {

for (uint256 funderIndex = 0; funderIndex < funders.length; funderIndex++){
address funder = funders[funderIndex];
addressToAmountFunded[funder] = 0;

}
funders = new address;

(bool callSuccess, ) = payable(msg.sender).call{value: address(this).balance}("");
require(callSuccess, "CALL FAILED");
}

}

you are not importing PriceConverter.sol library in your FundMe contract.

[COSMICnoob80]

Still showing the same error.

@COSMICnoob80 you need to import AggregatorV3Interface in PriceConverter.sol library and then Import PriceConverter.sol in your FundMe.sol contract.

then use PriceConverter for uint256 inside FundeMe contract
like this using PriceConverter for unit256

Please watch the video carefully and try to understand each step also I would suggest you to code along so that you don't run into such issues.
