MongoTemplate findAndModify for document insertion

Given a document with the below structure:

{
  "_id": "XXXX01",
  "otherAttributes", "....",
  "child": [{
    "_id": "YYYY01",
    "otherAttributes", "....",
    "grandChild": [{
      "_id": "ZZZZ01",
      "otherAttributes", "...."
    }]
  }]
}

Using raw mongo dialect, the below are achievable:

Insert root

db.collection.findAndModify({
  query: { "_id": "XXXX01" },
  update: {
    "_id": "XXXX01",
    "otherAttributes", "....",
    "child": [{
      "_id": "YYYY01",
      "otherAttributes", "....",
      "grandChild": [{
        "_id": "ZZZZ01",
        "otherAttributes", "...."
      }]
    }]
  },
  upsert: true
})

But a similar findAndReplace with mongoTemplate eg.

var document = new Document();
mongoTemplate.getConverter().write(javaObjectRepresentingTheDocument, document);
update = Update.fromDocument(document) // Primary because I dont want to set each field individually
query.addCriteria(
  Criteria.where("id").is("XXXX01")
);
mongoTemplate.findAndModify(query, update,
  FindAndModifyOptions.options().upsert(true).returnNew(true),
  javaObjectRepresentingTheDocument.getClass(),
  collection
)

results in the below error:

Caused by: java.lang.IllegalArgumentException: Invalid BSON field name _id
  at org.bson.AbstractBsonWriter.writeName(AbstractBsonWriter.java:534) ~[bson-4.4.3.jar:na]
  ...

The reason I would want to use findAndReplace over upsert is:

1. I need the current object
2. Generalize code ie. the same method(findAndReplace) is useful for both insertion and updation at all levels viz. the root document, a nested document eg. child, a deeply nested document eg. grandChild

I have been successful is getting the same work for child and grandChild nested documents by using

update.addToSet("$[parentSelector]", javaObjectRepresentingTheNestedDocument)
.filterArray(Criteria.where("parentSelector._id").is(<parentSelectorValue>))

but not being able to the get the same working for the root document. Can someone provide some guidance?
