Neo4j Procedure throwing error - neo4j

Question

I'm just starting to learn how to write procedures. My simple proof of concept still isn't passing muster when Neo4j starts up. Here is the code:
import java.util.ArrayList;
import java.util.stream.Stream;
import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.logging.Log;
import org.neo4j.procedure.Context;
import org.neo4j.procedure.Mode;
import org.neo4j.procedure.Procedure;
public class Procedures {
#Context
public GraphDatabaseService db;
#Context
public Log log;
#Procedure( name = "create_user", mode = Mode.WRITE )
public Stream<Create_user_response> create_user() {
ArrayList<Create_user_response> myList = new ArrayList<>();
Create_user_response res1 = new Create_user_response();
res1.out = 1;
myList.add(res1);
Stream<Create_user_response> myStream = myList.stream();
return myStream;
}
}
Here's my Create_user_response class:
public class Create_user_response {
public int out;
}
When Neo4j starts up it complains that my procedure needs to return a stream of records. I'm new to streams so I must be doing something wrong but just can't figure it out.
I appreciate any help. Thanks.

Turns out I had a bad dependency,
<dependency>
<groupId>org.neo4j.test</groupId>
<artifactId>neo4j-harness</artifactId>
<version>3.2.3</version>
<scope>test</scope>
</dependency>
wasn't working. I found it in a tutorial and its in Maven, but for some reason I must not have been doing something correctly with it.
