Chainlink keeper 未运行 performUpkeep，但 checkUpkeep 返回 true

Question

正如标题所说，似乎所有守门员运行 performUpkeep 的条件都已满足，但它没有被调用。

这里是维护链接：https://keepers.chain.link/kovan/upkeeps/413

这是合同：https://kovan.etherscan.io/address/0x969F42c92A6aeBD925982CCc1C943185B6D0E357#code

以下是相关代码：

function checkUpkeep(bytes calldata checkData) external view override returns (bool upkeepNeeded, bytes memory performData) {
        upkeepNeeded = shouldHarvest();

        // We don't use the checkData
        // checkData was defined when the Upkeep was registered
        performData = checkData;
    }

    function performUpkeep(bytes calldata performData) external override {
        harvest();

        // We don't use the performData
        // performData is generated by the Keeper's call to your `checkUpkeep` function
        performData;
    }

    function shouldHarvest() internal view returns (bool) {
        bool hasPendingOutput = IMasterChef(chef).pendingBall(poolId, address(this)) > harvestThreshold;
        bool harvestCondition = hasPendingOutput && !paused();
        return harvestCondition;
    }

我尝试过的事情：

• 通过进行新的维护来提高气体限制：https://keepers.chain.link/kovan/upkeeps/416
• 在 checkUpkeep 上使用没有“view”修饰符的合约（如@chainlink/contract npm 包中的接口：https://keepers.chain.link/kovan/upkeeps/414

我使用 Remix 查询 https://kovan.etherscan.io/address/0x969F42c92A6aeBD925982CCc1C943185B6D0E357#code 上的 checkUpkeep 以查看它是否返回 true。

看来问题出在收获功能上：

function harvest() public whenNotPaused onlyEOA

onlyEOA 修饰符可能会阻止函数被调用，因为 Keepers 可能会从智能合约中调用它。
