[Bug]: Python Lambda Layer versions > 61 throw an Opentelemetry import error

[janritter]

Problem Description

When upgrading a Lambda Function that previously ran fine with Instana layer version 61 to 62 or above the execution fails with the error Unable to import module 'instana': No module named 'opentelemetry'

Minimal, Complete, Verifiable, Example

Create an AWS Lambda Function with Python 3.12 / arm64 and the following code:

def handler(event, context):
    return context.function_name

Set the handler to instana.lambda_handler and add the layer with the ARN arn:aws:lambda:eu-central-1:410797082306:layer:instana-python:62

Configure the following environment variables:
INSTANA_AGENT_KEY=test-agent-key
INSTANA_ENDPOINT_URL=https://serverless-blue-saas.instana.io
LAMBDA_HANDLER=app.handler
LAMBDA_TIMEOUT=30

Try to execute the Lambda and it will fail with Unable to import module 'instana': No module named 'opentelemetry'

Hello, @janritter. Thanks for reporting this issue.

We have migrated from the OpenTracing dependency to the OpenTelemetry dependency, which is contained in the newer versions of the AWS Lambda Layer.

We will definitely fix it and let you know when a new version is available. Meanwhile, can you downgrade to version 61?

Hello, @janritter. We published a new version of the AWS Lambda Layer, numbered v66.

Could you please confirm this new version works on your environment.
