- Toolchain Version: v1.0.0
- Data Size: 9000 vertices, 20000 edges

执行"算法分析"的任意算法，均返回"网络异常，请稍后重试"
试过 hubble 原生版本 以及 最新docker版本，均报错。

看了下网络：

请求 URL: http://xxxx/api/v1.2/graph-connections/2/algorithms/sameneighbors
请求方法: POST
状态代码: 405

响应：{"timestamp":"2023-04-21 15:39:21","status":405,"error":"Method Not Allowed","message":"Request method 'POST' not supported","path":"/api/v1.2/graph-connections/2/algorithms/sameneighbors"}

### Expected & Actual behavior (期望与实际表现)

不应返回该类报错

### Vertex/Edge example (问题点 / 边数据举例)

_No response_

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

_No response_

Reproduce the request to /api/v1.2/graph-connections/2/algorithms/sameneighbors described in the report, using the stated v1.0.0 environment or Docker setup. Trace the API handling for algorithm analysis and compare the requested POST method with the endpoint’s supported method; done means algorithm requests no longer return HTTP 405 or the generic network-error message.
