Lesson 4: Getting error while withdrawing the fund

[ghost]

When trying to withdraw the funded amount, I am getting this error:

Code:

//SPDX-License-Identifier: MIT

pragma solidity 0.8.7;

import "./PriceConverter.sol";

contract FundMe{
    using PriceConverter for uint256;
    address public i_owner;

    uint256 public minimunAmountInUsd = 5 * 1e18;
    address[] public funders;
    mapping(address => uint256) public addressToAmountFunded;

    constructor(){
        i_owner = msg.sender;
    }

    function fund() public payable {
       require((msg.value).getConversionRate() >= minimunAmountInUsd, "Didn't send enough!");
       funders.push(msg.sender);
       addressToAmountFunded[msg.sender] += msg.value;
    }   

  
    function withdraw() payable onlyOwner public {
        for(uint256 funderIndex = 0; funderIndex <= funders.length; funderIndex++){
            address funder = funders[funderIndex];
            addressToAmountFunded[funder] = 0;
        }
         funders = new address[](0);
           (bool callSuccess,)=payable(msg.sender).call{value: address(this).balance}("");
           require(callSuccess,"call failed!");
    }

     modifier onlyOwner(){
        require(msg.sender == i_owner, "Sender is not owner");
        _;
    }
}

yes, same issue here. did you find a solution?

[ghost]

Yes there was a minor mistake on for loop.
solution: on for loop, instead of funderIndex < funders.length, it should be < only.

 for(uint256 funderIndex = 0; funderIndex < funders.length; funderIndex++){
          ...
        }

Figured out my mistake as well :)
