   ### Bug Type (问题类型)
   
   other exception / error (其他异常报错)
   
   ### Before submit
   
   - [x] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 
[FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have 
confirmed and searched that there are no similar problems in the historical 
issue and documents)
   
   ### Environment (环境信息)
   
   - Server Version: 1.5.0 (master)
   
   
   
   
   ### Expected & Actual behavior (期望与实际表现)
   
   There is a reflection call error in the getState method of the PD  
RaftEngine.java file. This method attempts to retrieve the state field value of 
a Replicator object through reflection, but incorrectly uses this.raftNode as 
the parameter instead of the passed Replicator r parameter.
   
   ```
   private Replicator.State getState(Replicator r) {
       var clz = r.getClass();
       try {
           var f = clz.getDeclaredField("state");
           f.setAccessible(true);
           var state = (Replicator.State) f.get(this.raftNode); // Error: 
should use r instead of this.raftNode
           f.setAccessible(false);
           return state;
       } catch (NoSuchFieldException | IllegalAccessException e) {
           log.info("getReplicatorGroup: error {}", e.getMessage());
           return null;
       }
   }
   
   ```
   
   ### Vertex/Edge example (问题点 / 边数据举例)

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