### Bug Type (问题类型) rest-api (结果不合预期) ### Before submit - [X] I had searched in the [issues](https://github.com/apache/hugegraph-toolchain/issues) and found no similar issues. ### Environment (环境信息) - Server Version: v1.5.0 - Toolchain Version: v1.5.0 ### Expected & Actual behavior (期望与实际表现) 调用‘kneighbor‘接口时，返回结果时，‘withPath‘为‘true‘与为‘false‘’的场景不兼容
