Error: Member "send" not found or not visible after argument-dependent lookup

Question

I am trying to compile the following smart contract:

pragma solidity ^0.5.1; 
contract Governmental{
   uint constant TWELVE_HOURS = 12;
   
   function lendGovernmentMoney ( address buddy ) public  returns ( bool ) {
      address owner;
      uint[] memory creditorAddresses;
      uint lastTimeOfNewCredit =0;
      uint amount = msg. value ;
      uint creditorAmounts = 0;
      uint profitFromCrash = 0;
      uint round = 0;
      uint lastCreditorPayedOut = 0;
       
      // check the condition to end the game
      if ( lastTimeOfNewCredit + TWELVE_HOURS > block . timestamp ) {
         msg.sender.send ( amount );
         // Sends jacpot to the last creditor
         creditorAddresses[creditorAddresses.length - 1].send ( profitFromCrash );
         owner.send (this.balance);
         // Reset contract state
         lastCreditorPayedOut = 0;
         lastTimeOfNewCredit = block . timestamp ;
         profitFromCrash = 0;
         creditorAddresses = new address [](0);
         creditorAmounts = new uint [](0);
         round += 1;
         return false ;
      }
   }
}

I am getting the error:

prg17.sol:20:10: Error: Member "send" not found or not visible after argument-dependent lookup in uint256. creditorAddresses[creditorAddresses.length - 1].send ( profitFromCrash ); ^--------------------------------------------------^

Somebody please guide me.

Answer 1

creditorAddresses is declared as a uint array.

uint[] memory creditorAddresses;

Prabably you meant to declare it as an address array

address payable[] memory creditorAddresses;

Also this code creditorAddresses[creditorAddresses.length - 1] won't work when the array is empty. Which is the case if the memory array isn't initialized like the snippet.
