lambda traces and application traces (mongo, s3) not grouped

[jeusdi]

Describe the bug I've configured opentelemetry on my aws lambdas using opentelemetry provided layers.

I mean, I'm using javaagent + collector layer attached to my lambdas, following this agent layer documentation and this collector layer documentation](https://opentelemetry.io/docs/faas/lambda-collector/).

That means that I'm using openTelemetry agent + collector and I'm autoinstrumention my code using agent.

After that, my traces are generated, but not aligned on X-Ray console.

I mean, opentelemetry agent is instrumenting my mongo and S3 access. Lambda traces are also generated.

So, I'm getting traces for:

• lambda context executation traces
• S3 access traces
• mongodb access traces

However, traces appear not related between them:

I don't quite figure out how to create relation between them in order to putt all it together.

I've took a look on logs. Following traces are generated:

Any ideas?

What did you expect to see? Traces with hierarchy

What version of collector/language SDK version did you use? layer verions:

• arn:aws:lambda:eu-west-1:901920570463:layer:aws-otel-collector-amd64-ver-0-90-1:1
• arn:aws:lambda:eu-west-1:184161586896:layer:opentelemetry-javaagent-0_5_0:1

What language layer did you use? Java
