chainlink - Chainlink keeper 未运行 performUpkeep，但 checkUpkeep 返回 true

Question

就像标题所说的那样，似乎已经满足了 keeper 运行 performUpkeep 的所有条件，但它并没有被调用。

这是维护链接：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增加 gas 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 在https://kovan.etherscan.io/address/0x969F42c92A6aeBD925982CCc1C943185B6D0E357#code上查询 checkUpkeep以查看它是否返回 true。

Answer 1

似乎问题出在收获功能中：

function harvest() public whenNotPaused onlyEOA

该onlyEOA修饰符可能会阻止调用该函数，因为 Keepers 可能会从智能合约中调用它。
