Question

我终于设法让我的API进入可以将其上传到AWS Lambda的状态，然后每当我尝试使用API网关进行测试时，我都会收到以下错误。

    {
      "errorType": "AggregateException",
      "errorMessage": "One or more errors occurred. (Object reference not set to an instance of an object.)",
      "stackTrace": [
        "at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions)",
        "at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)",
        "at lambda_method(Closure , Stream , Stream , ContextInfo )"
      ],
      "cause": {
        "errorType": "NullReferenceException",
        "errorMessage": "Object reference not set to an instance of an object.",
        "stackTrace": [
          "at Amazon.Lambda.AspNetCoreServer.APIGatewayProxyFunction.MarshallRequest(InvokeFeatures features, APIGatewayProxyRequest apiGatewayRequest)",
          "at Amazon.Lambda.AspNetCoreServer.APIGatewayProxyFunction.<FunctionHandlerAsync>d__12.MoveNext()"
        ]
      }
    }

代码：

    public class LambdaEntryPoint : 
    Amazon.Lambda.AspNetCoreServer.APIGatewayProxyFunction
    {
        protected override void Init(IWebHostBuilder builder)
        {
            try
            {
                builder
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseStartup<Startup>()
                    .UseApiGateway();
            }
            catch (Exception ex)
            {
                LambdaLogger.Log("Exception throw in LambdaEntryPoint: " + ex);
            }
        }
    }

我没有从我的Startup或LambdaEntryPoint中记录任何异常。我对AWS很陌生，所以我不确定还有什么要检查。

关于这个的任何想法？

这可能与AWS的某个人在AWS github repo上与其他人在AWS .NET Lambda集成中解决的问题相同： https://github.com/aws/aws-lambda-dotnet/issues/168
