我有这样的 SQSClient 设置：

var client = new AmazonSQSClient();
new AWSSdkTracingHandler(AWSXRayRecorder.Instance).AddEventHandler(client);
return client;

现在当我打电话给客户

var receiveResult = _amazonSqs.ReceiveMessage(_longPollRequest);

我得到以下异常

Amazon.XRay.Recorder.Core.Exceptions.EntityNotAvailableException was 
unhandled by user code
HResult=-2146233088

我尝试添加类似AWSXRayRecorder.Instance.BeginSegment();但不知何故需要traceId我似乎无法满足的东西

AWSXRayRecorder.Instance.BeginSegment("ReceiveMessage", Guid.NewGuid().ToString());
var receiveResult = _amazonSqs.ReceiveMessage(_longPollRequest);
AWSXRayRecorder.Instance.EndSegment();

例外：

System.ArgumentException was unhandled by user code

我一定做错了什么，但我没有看到。

您可以使用TraceId.NewId();. 此类在Amazon.XRay.Recorder.Core.Internal.Entities命名空间中可用。

正如 Ruslan 所说，我们（AWS X-Ray 团队）在 AWS X-Ray 官方论坛上非常活跃。不幸的是，您的链接帖子似乎已发布在 AWS .NET 语言特定论坛中。如果将来发布到X-Ray 特定论坛的帖子，我们更有可能快速回复它们。

谢谢，
