Ruby on rails MongoId未更新模型数据，也未显示任何错误

我有两个系统使用mongo版本3.4.16在AWS平台上工作。目前，我将它们移动到了GCP，因此，我使用了更新的mongo版本4.2.8。 首先要记住的是，在我更换服务器之前，这些系统已经运行了很多年。两者都使用相同的mongo服务器，也使用相同的集合和凭据。问题是：

有问题的系统能够在MongoDB上查询和创建数据，但不能更新任何模型的任何属性。我尝试使用同样在rails控制台上运行的web界面来更新运行该应用程序的属性，但它也存在同样的问题。除了mongo版本，我没有改变任何东西

:023 > user = User.where({email: 'email@test.com'}).first
:024 > user.name
 => "user name"
:025 > user.name = "new user name"
 => "new user name"
:026 > user.save!
 [paperclip] Saving attachments.
  => true
:027 > user = User.where({email: 'email@test.com'}).first
:028 > user.name
 => "user name"

第二个系统具有相同的gem版本（当我谈论mongodbgems时），并且它仍在工作（更新模型属性），甚至将mongo版本从3.4.16版本更改为4.2.8版本（正如我前面提到的）。你知道会发生什么吗

有问题的系统包括：

用于确定/验证正在发送哪些命令以及发送到哪个数据库

通过mongo shell检查集合，在更新前后验证其内容。

感谢您的回答，但是系统目前不支持此功能，部分问题是我无法更新系统gems，因为我需要更新所有的gems以及语言功能，这是不可能的（在我问这个问题之前我已经试过了）app/models/command\uu log\u subscriber.rb:2:in`'：未初始化的常量CommandLogSubscriber:：Mongo（namererror），听起来像是某种依赖性问题。在任何情况下，驱动程序2.6都支持命令监视，所以它应该以某种方式工作。
