Question

I have the query below in a Spring boot application using Spring data neo4j. When I run the query as a standalone cypher query, it returns all the data that I am looking for, however, when I run the same query in the spring boot application, it does not return all the data I need. It just goes about a level or 2 deep.

 MATCH path = (stepNode:StepNode {stepNodeId: "<id_goes_here>"})-[:PARENT*0..]-(descendant)
   WITH collect(path) AS paths, stepNode, collect(distinct descendant) AS descendants
   UNWIND descendants AS d
   OPTIONAL MATCH (d)-[r]->(related)
   RETURN stepNode, paths, collect(distinct r) AS relationships, collect(distinct related) AS relatedNodes;

Is there anything I am missing?

This is the query in the spring boot repository

 @Query("""
        MATCH path = (stepNode:StepNode {stepNodeId: "421d419a-05a5-4cd6-81f5-3fe5336eead0"})-[:PARENT*0..]-(descendant)
        WITH collect(path) AS paths, stepNode, collect(distinct descendant) AS descendants
        UNWIND descendants AS d
        OPTIONAL MATCH (d)-[r]->(related)
        RETURN stepNode, paths, collect(distinct r) AS relationships, collect(distinct related) AS relatedNodes;
     """)
    Optional<StepNode> findTreeByRootNodeId(UUID rootNodeId);

I have also noticed that in my logs, right before my query is executed, spring data neo4j displays some data that matches the element_ids of the data that I am able to retrieve from a related entity. Below is the data that is pulled before my query runs with the query

The data that I get when I run the query directly in cypher (I used the table because it might be easier to compare than the graph)

I am using spring boot 3.2.5 and the spring-boot-starter-data-neo4j compatible with it

Any help would be appreciated
