Expected & Actual behavior (期望与实际表现)

点击：['tag:收益目标']目标节点，无法扩展，显示，没有更多节点。
我使用 gremlin语句直接查询server ：可以查到关联的边和节点。

Vertex/Edge example (问题点 / 边数据举例)

No response

Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)

The issue you're experiencing with node expansion in the Hubble tool, where clicking on a node labeled "收益目标" does not expand to show more nodes, could be due to several factors. Here are some potential reasons and solutions:

1. Query Optimization: Hubble might be applying optimizations that limit the number of results returned during node expansion. This includes parameters like max_degree, capacity, and limit, which can restrict the number of nodes or edges returned. You might want to check these settings and adjust them if necessary ^[1].

2. Error Handling and Result Parsing: Hubble's error handling and result parsing mechanisms might be affecting the results. It handles exceptions and parses results differently than direct Gremlin queries, which could lead to discrepancies ^[2][3].

3. Graph View Construction: The way Hubble constructs the graph view from the query results might involve additional filtering or processing, which could be causing the issue ^[2].

4. Schema Constraints: Although not explicitly documented, schema constraints or configurations related to VertexLabel, EdgeLabel, or IndexLabel might impact node expansion. Ensure that the schema is correctly defined and that there are no constraints that could prevent node expansion.

5. Debugging and Logging: While specific debugging or logging capabilities weren't found, checking any available logs for errors during the node expansion process might provide insights.

If these suggestions don't resolve the issue, you might need to further investigate the specific configurations and settings in your Hubble environment.
