Forge build error

[Tezei]

Hiya guys, When I tried forge build command I am getting error as follows:

[⠒] Compiling... [⠃] Compiling 2 files with Solc 0.8.19 [⠊] Solc 0.8.19 finished in 731.33ms Error: Compiler run failed: Error (9553): Invalid type for argument in function call. Invalid implicit conversion from literal_string "" to bytes calldata requested. --> src/Raffle.sol:161:45:	161	(bool upkeepNeeded, ) = checkUpkeep("");

Please, advise.

10x in advance

Comment out the required calldata in your checkUpkeep function like this:

function checkUpkeep(
        bytes memory /* checkData */
    ) public view returns (bool upkeepNeeded, bytes memory /*performData*/) {
        bool timeHasPassed = ((block.timestamp - s_lastTimeStamp) >=
            i_interval);
        bool isOpen = (s_lotteryState == LotteryState.OPEN);
        bool hasBalance = address(this).balance > 0;
        bool hasPlayers = s_entrants.length > 0;
        //this will return upkeepNeeded due to the explicit declaration in the return statement above
        upkeepNeeded = timeHasPassed && isOpen && hasBalance && hasPlayers;
        return (upkeepNeeded, "");
    }
