I am using mongo java drivers as below:
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.10.1</version>
</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver-reactivestreams</artifactId>
<version>1.11.0</version>
</dependency>
When I define a simple pipeline as:
List<Bson> pipeline = Arrays.asList(
Aggregates.project(Projections.fields(
Projections.computed("id", "$fullDocument._id")
))
);
After my doing some CRUD operations, I always get these 'null' output:
ChangeStreamDocument{resumeToken={"_data": "825C8B65510000000129295A1004E2034BD33C7D40DE92CB94E139C92CB146645F696400645C8B65511B2DF1941FD846250004"}, namespace=null, fullDocument=null, documentKey=null, clusterTime=null, operationType=null, updateDescription=null}

Did not it should be like :
{
"id": xxxxxxxxxx
}
Please correct me.
