I got the "Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?" in remix while using the drawWinner function

    function withdrawal(uint256 amount) public {
        require(amount <= 100000000000000000, "error");
        payable(msg.sender).transfer(amount);
    }

    fallback() external payable {}

    receive() external payable {}
}

Answer 1

Usually it’s an error with the syntax. I’m unsure why you’ve denoted the withdrawal functionality as payable, as it isn’t intending to receive ether or modify any state variables. This would likely result in a gas estimation error. Try removing the payable declaration.
