GeoServer - 使用 Rest API 创建 featureType 失败并出现错误“java.lang.NullPointerException”

Question

我已经使用 Rest API 成功创建了一个数据存储。使用 GeoServer Web 面板创建图层时没有任何问题。但是我无法使用 Rest API 创建相同的图层。

工作空间和存储名称分别为“test”和“gis_osm_adminareas_a_07_1”。

Store 的类型为“Shapefile”并指向“.shp”文件。还有“.dbf”、“.prj”和“.shx”文件在与所述“.shp”文件相同的位置共享相同的基本名称。

ogrinfo -al -so gis_osm_adminareas_a_07_1.shp

命令正确分析并给出shapefile相关信息。

这是我使用的 URL 和帖子正文：

                    "length": 10
                },
                {
                    "name": "name",
                    "minOccurs": 0,
                    "maxOccurs": 1,

                    "binding": "java.lang.String",
                    "length": 100
                }
            ]
        }
    }
}

操作失败，出现 500 内部服务器错误，响应正文中没有发送回错误信息。但是堆栈跟踪出现在日志中。这是错误日志的相关部分：

我尝试了很多不同的帖子主体组合，但都没有成功。我还尝试复制使用 Web 面板创建图层时创建的“resource.json”，并将其发送到 featureType 端点，这也不起作用。

任何帮助表示赞赏。谢谢！
