“光标”选项是必需的，来自每个聚合的错误

我从特定 NodeJS 应用程序的每个 mongoose 聚合中收到 The 'cursor' option is required 错误。但在同一系统中，具有猫鼬聚合的其他应用程序运行良好。 解决办法是什么？ 顺便说一句，相同的应用程序在其他系统中运行良好

Code

function getTestParams(testconductedid, mark) {
return new Promise(function (resolve, reject) {
    Mark.aggregate([
        {
            $match: {
                testconductedid: testconductedid,
            }
        },
        {
            $group: {
                _id: '$testconductedid',
                max: { $max: '$total' },
                avg: { $avg: '$total' },
                rank: { $sum: { '$cond': [{ '$lt': [mark, "$total"] }, 1, 0] } },
            }
        }
    ], function (err, results) {
        console.log(JSON.stringify(results));
        resolve(results);
    })
});

}

Error
