命令游标未返回结构正确的响应

Question

我把我的mongo从2.6更新到了4。我遇到了聚合查询的问题。我得到的信息是：the command cursor did not return a correctly structured response。

正如在this anwser中所述，我将以下配置放在

ini_set('mongo.native_long', false);
ini_set('mongo.long_as_object', true);

但是现在我得到了错误Notice: Object of class MongoInt64 could not be converted to int。

有没有人知道怎么解决这个问题？

php --ri mongodb的结果

php --ri mongodb

抛出异常的代码

$queryBuilder = $this->createQueryBuilder();

        return $this->createAggregationBuilder()->match()
                ->field('delivery')->references($delivery)
                ->field('dateDeleted')->equals(null)$aggregation
                ->group()
                    ->field('id')
                    ->expression(null)
                    ->field('count')
                    ->sum(1)->execute()->getSingleResult();

Answer 1

通过添加ini_options，解决了the command cursor did not return a correctly structured response的错误。但由于一些数据已经存在于数据库中，这是由旧的Mongo驱动程序创建的，它无法获取数据。

因此，我需要删除所有文档才能重新启动一个干净的数据库。
