function startLottery(

        uint256 _priceTicketInCake,
        uint256 _discountDivisor,
        uint256[6] calldata _rewardsBreakdown,
        uint256 _treasuryFee
    ) external override onlyOperator {
        require(
            (currentLotteryId == 0) || (_lotteries[currentLotteryId].status == Status.Claimable),
            "Not time to start lottery"
        );

        require(
            ((_endTime - block.timestamp) > MIN_LENGTH_LOTTERY) && ((_endTime - block.timestamp) < MAX_LENGTH_LOTTERY),
            "Lottery length outside of range"
        );

        require(
            (_priceTicketInCake >= minPriceTicketInCake) && (_priceTicketInCake <= maxPriceTicketInCake),
            "Outside of limits"
        );

        require(_discountDivisor >= MIN_DISCOUNT_DIVISOR, "Discount divisor too low");
        require(_treasuryFee <= MAX_TREASURY_FEE, "Treasury fee too high");

        require(
            (_rewardsBreakdown[0] +
                _rewardsBreakdown[1] +
                _rewardsBreakdown[2] +
                _rewardsBreakdown[3] +
                _rewardsBreakdown[4] +
                _rewardsBreakdown[5]) == 10000,
            "Rewards must equal 10000"
        );

我按照 Pancakeswap Lottery 的说明（https://bscscan.com/address/0x5af6d33de2ccec94efb1bdf8f92bd58085432d2c#code）写“startLottery”。但是写这个函数是错误的。我使用元掩码。我还将 ChainLink 的随机数生成器用于我的彩票。

我正在使用 The Graph 作为我的彩票数据。但我的实体是空的。我认为原因是我不能写“startLottery”。
