您用来生成VDM的EDMX文件与远程OData服务响应不兼容。请要求OData服务的维护者提供最新的元数据文件。您也可以尝试直接从下载http://[URL]/odata/v2/$metadata。
我发现您附加的JSON示例有效负载中约有一半与API Business Hub上发布的EDMX文件不兼容。
响应中包含无法与元数据匹配的未知实体属性：

"closedDateTime": null "timeToFill": null "jobReqGUId": null "overallScaleName": null "lastModifiedProxyUserId": null "positionNumber": null "age": null
不幸的是，错误没有得到适当处理，并且将关闭任何反序列化尝试。由于这是在SAP Service SDK的第三方Olingo库中发生的，因此我们无法修复或更改它，也无法提供有意义的解决方法。
您需要确保从头到尾使用正确的元数据文件。
感谢您的分析。我多次尝试使用同一系统中的元数据，但没有碰到运气。我想SFSF元数据，生成器和Cloud SDK目前不是最好的朋友。我将停放该项目，直到有使用真实SFSF系统的更新示例或教程为止。无论如何，谢谢您的回答，绝对有帮助！
