powertools-lambda-dotnet Bug: Batch Processing breaks Tracing

Expected Behaviour

Tracing show show segments within x-ray when the batch processing utility is used.

I am unable to get Tracing to work (previously worked fine before converting to using the Batch Processing Powertools functionality).

Current Behaviour

Receiving this error on invocation:

{
  "errorType": "NullReferenceException",
  "errorMessage": "Object reference not set to an instance of an object.",
  "stackTrace": [

### Possible Solution

Unable to triage this issue.

### Steps to Reproduce

Write a lambda function that utilizes both batch processing and tracing via annotations. 

### Powertools for AWS Lambda (.NET) version

latest

### AWS Lambda function runtime

dotnet6

I have created this MVP sample repository to demonstrate the issue. The code is pretty simple, but is throwing the exception noted above. What am I doing wrong, or is this a bug?

Hi @CoreySchnedl as a workaround while we do a release to fix this bug, if you are not using the Metadata in X-Ray you could change the POWERTOOLS_TRACER_CAPTURE_RESPONSE environment variable to false. This will stop Tracing from trying to add the RecordHandlerResult to the Metadata field in X-Ray which is the cause for the exception you are seeing.

Another approach if you don't want to lose the Metadata from other methods that have the Tracing decorator you could manually add a Tracing subsegment.


public class CustomSqsRecordHandler : ISqsRecordHandler
{
    // [Tracing] -- remove the decorator
    public async Task<RecordHandlerResult> HandleAsync(SQSEvent.SQSMessage record, CancellationToken cancellationToken)
    {
        
        /*
         * Your business logic.
         * If an exception is thrown, the item will be marked as a partial batch item failure.
         */
        Logger.LogInformation($"Handling SQS record with message id: '{record.MessageId}'.");

        Logger.LogInformation($"Handling record with body: {record.Body}");

        var product = JsonSerializer.Deserialize<Product>(record.Body);

        Tracing.WithSubsegment("Custom Record Handler", (subsegment) =>
        {
           // if you uncomment this line you will see that it will fail
            // subsegment.AddMetadata("Data", RecordHandlerResult.FromData(product));

            SomeCoolFunction();
            SomeCoolFunction();
        });

        Logger.LogInformation($"Handling product with id: {product!.SomeCoolField}");
        
        return await Task.FromResult(RecordHandlerResult.FromData(product));
    }

    [Tracing]
    private static bool SomeCoolFunction()
    {
        return true;
    }
}
