RoboMongo不能使用阵列滤波器？

Question

来自＆＃34; How to update collection and increment hours for ISO date＆＃34;。

似乎RoboMongo无法使用数组过滤器执行查询：

同样的查询，如果在通过Mongo shell执行时查找：

> db.collection.update({
...     "results.score": {
...         "$exists": true
...     }
... }, {
...     "$mul": {
...         "results.$[result].score": 10
...     }
... }, {
...     "arrayFilters": [{
...         "result.score": {
...             "$exists": true
...         }
...     }],
...     "multi": true
... })
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })

查看Mongo服务器中的日志记录，看起来查询是否正确传递，但仍然失败：

D COMMAND  [conn4] run command test.$cmd { update: "collection", updates: [ { q: { results.score: { $exists: true } }, u: { $mul: { results.$[result].score: 10.0 } }, multi: true, upsert: false } ], ordered: true, $db: "test" }

来自shell的日志不同：

我无法看到任何暗示某些事情出错的事情（当然，除了断言失败）。

• 在Mongo shell成功的地方导致RoboMongo失败的原因是什么？
• 这些日志中有什么东西可以告诉我错误吗？
