How to update MongoDB document with DbRef using spring mongoTemplate

@Document
class Entity1 {
  @Id
  String id
  @DbRef(lazy=true)
  Entity2 entity2;
  String test;
}

mongoTemplate.upsert(
  new Query(Criteria.where("entity2.$id").is(entity2Id),
  new Update().set("test", "newValue"),
  Entity1.class);

I got Found $id field without a $ref before it, which is invalid

My question is how to do this with DbRef.

Pass the object to where the request is, not the id. Create and save Entity2 in DB, then use entity2 instance and change your code to: where ("entity2"). Is (entity2)
