Fiware Orion：Geoqueries 不适用于 geojson 多边形，只有点似乎有效

Question

我的地理查询有问题，它似乎只在存储的实体位置 geojson 类型是“点”类型时有效，但不适用于多边形。

我是运行 Orion 2.5.2 docker

我都在附近测试过

https://{{orion}}/v2/entities/?type=Building&georel=near;maxDistance:2000&geometry=point&coords=51.706774495,8.776277548

还有intersects/coveredBy:

https://{{orion}}/v2/entities/?type=Building&georel=intersects&coords=51.70683451303916,8.77602696418762;51.706462195326104,8.776386380195618;51.70663838176868,8.776847720146177;51.706965820787424,8.776482939720154;51.70683451303916,8.77602696418762&geometry=polygon

但 orion 总是 returns 示例条目的空结果：我在规范和 orion 手册中都找不到任何提示这只适用于点。对我来说似乎是个错误

        ]
      ]
    }
  }
}

我可以解决。结果我输入的是“geojson”而不是“geo:json”。更改为后者现在有效。
