Working with remix and Kovan, I keep getting the following error:

Gas estimation failed
Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
The execution failed due to an exception. Reverted

I have also tried:

contract Borrower {
    ILendingPoolAddressesProvider provider;
    address dai;
    uint amount;
    
    
    constructor() public {
        provider = ILendingPoolAddressesProvider(0x506B0B2CF20FAA8f38a4E2B524EE43e1f4458Cc5);
        dai = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;
        amount = 1;
    }
    

    function makeDeposit() public payable  {
        ILendingPool lendingPool = ILendingPool(provider.getLendingPool());
        // IERC20(dai).approve(provider.getLendingPoolCore(), msg.value);
        lendingPool.deposit(dai, msg.value, 0);
    }
}
