Issue with OpenTelemetry.Contrib.Instrumentation.AWSLambda

List of all OpenTelemetry NuGet packages and version that you are using (e.g. OpenTelemetry 1.0.2):

    <PackageReference Include="OpenTelemetry.Contrib.Instrumentation.AWS" Version="1.0.1" />
    <PackageReference Include="OpenTelemetry.Exporter.OpenTelemetryProtocol" Version="1.1.0-beta1" />
    <PackageReference Include="OpenTelemetry.Contrib.Instrumentation.AWSLambda" Version="1.1.0-beta1" />
    <PackageReference Include="OpenTelemetry.Instrumentation.Http" Version="1.0.0-rc8" />

Runtime version (e.g. net462, net48, netcoreapp3.1, net6.0 etc. You can find this information from the *.csproj file):

netcoreapp3.1

Is this a feature request or a bug?

What is the expected behavior?

Incoming http W3C trace headers are extracted and added to the active span created. Currently only headers from X-Ray are extracted according to the comments in this method.

What is the actual behavior? I am sending traceparent and tracestate headers from a client SPA to an AWS dotnetcore3.1 Lambda using this wrapper. Currently the trace context sent via HTTP headers are not automatically extracted via this wrapper, thus I have reverted to not use this wrapper and am manually creating my own Spans/extraction of context.

I'm also experiencing the same issue with a project I'm working with. Hope this can be solved soon.

Hi @khpeet and @jmpf2019 Thanks for opening this feature request. Adding support for W3C in the AWS Lambda instrumentation is on our backlog, however I cannot provide and ETA for it at the moment. I will provide an update as soon as possible.

Hi @srprash, same as previous comment ^, checking if there's any progress on this.

This should now be implemented by #408, check the release notes of 1.1.0-beta.2 here: https://github.com/open-telemetry/opentelemetry-dotnet-contrib/blob/main/src/OpenTelemetry.Instrumentation.AWSLambda/CHANGELOG.md
