Xml 使用 C# 的 AWS Lambda 上的序列化程序导致方法未找到异常

Question

我正在尝试在 AWS Lambda 运行ning c# 中使用 xml 序列化程序。在 AWS Lambda 上运行时，我不断收到以下错误：

{
    "Message": "There is an error in XML document (0, 0).",
    "Data": {},
    "InnerException": {
        "Message": "Method not found: 'System.Xml.XmlReader System.Xml.Serialization.XmlSerializationReader.get_Reader()'.",
        "Data": {},
        "InnerException": null,
        "StackTrace": "   at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderDataSetHandleParam.InitIDs()\n   at System.Xml.Serialization.TempAssembly.InvokeReader(XmlMapping mapping, XmlReader xmlReader, Object events, String encodingStyle)\n   at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, Object events)",
        "HelpLink": null,
        "Source": "Microsoft.GeneratedCode",
        "HResult": -2146233069
    },
    "StackTrace": "   at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, Object events)\n   at System.Xml.Serialization.XmlSerializer.Deserialize(TextReader textReader)\n   at erp.client.agility.Models.Soap.Inventory.GetItemsResponse.Load(XmlNode node)\n   at erp.client.agility.AgilityErpCommunicator.Send[TK,T](String url, HttpMethod method, TK content)\n   at erp.client.agility.AgilityErpCommunicator.GetInventoryForProduct(String sessionContextId, String itemCode)\n   at erp.Repository.impl.Agility.AgilityRepository.GetInventoryForProduct(List`1 itemCodes)\n   at erp.Handler.InventoryForProduct(Request request, ILambdaContext context)",
    "HelpLink": null,
    "Source": "System.Xml.XmlSerializer",
    "HResult": -2146233079
}

调用代码如下：

        XmlSerializer serializer = new XmlSerializer(typeof(DataSetHandleParam));
        this.ItemDatasetHandle = serializer.Deserialize(reader) as DataSetHandleParam;

当我在本地运行时 (Windows 10)，我没有收到错误。

来自package.json：

"System.Xml.XmlSerializer": "4.3.0"

知道为什么会这样吗？

编辑：我打开了 AWS 的支持票。这是一个错误——他们正在调查它。
