Summary

I have a problem with an aggregation that works in Compass and VScode Extension but not in JAVA via spring-boot-starter-data-mongodb.
I have debugged all the way to the driver, and everything seemed normal.

Please provide the version of the driver. If applicable, please provide the MongoDB server version and topology (standalone, replica set, or sharded cluster).

Driver version: 4.6 and 4.7
Mongo Server: MongoDB Atlas version 6.0.0 

How to Reproduce

I have 3 collections:

1. device

{
  _id: ObjecId,
  name: string,
  ...
}

1. hardwareInventory

{
  _id: ObjectId,
  dictionaries: {
    Bios Information: [Object],
    Operating System: [
      {
        Name: String,
        OS StartUp: {
          value: Date,
          unit: String,
          ...
        },
        Service StartUp: {
          value: Date,
          unit: String,
          ...
        }
      }
    ]
    ...
  }
  ...
}
