otel python auto instrumentation

What happened?

Description

Steps to Reproduce

Expected Result

Actual Result

I'm setting up distributed tracing and end-to-end transaction monitoring for my services, which are hosted in an AKS (Azure Kubernetes Service) cluster and built using the Python framework. Since we use a microservices architecture, I'm implementing OpenTelemetry (OTel) with auto-instrumentation. This involves deploying the OTel Operator in AKS along with an OTel Collector and using Jaeger for tracing and ELK as backend storage

As part of the setup, I added the necessary Python-related annotations to enable tracing for four of my services. However, while I can see trace data for two of the services, the other two are not sending any data. Instead, I see an error message:

Could not find the ORIG_HANDLER or _HANDLER in the environment variables. This instrumentation requires the OpenTelemetry Lambda extension installed.

Since our environment is in Azure and not AWS, I don't understand why this error is appearing. What could be causing this issue, and how can I resolve it?

@swiatekm @TylerHelmuth @opentelemetrybot can any of you guys help me on this?

[tejaaa45]

@pmcollins can you help me on this?

[swiatekm]

Operator version

0.76.0

Do you actually mean the operator version here, or the Helm Chart version?

[tejaaa45]

@swiatekm its the helm chart version this is how i have done my setup--

helm install opentelemetry-operator open-telemetry/opentelemetry-operator --namespace opentelemetry-operator --create-namespace --set "manager.collectorImage.repository=otel/opentelemetry-collector-k8s"
--set admissionWebhooks.certManager.enabled=false
--set admissionWebhooks.autoGenerateCert.enabled=true

and i have added these annotations
instrumentation.opentelemetry.io/inject-python:true
instrumentation.opentelemetry.io/otel-python-platform:musl
instrumentation.opentelemetry.io/container-names

before adding this envi variables

• name: OTEL_PYTHON_DISABLED_INSTRUMENTATIONS
  value: aws-lambda

   i'm getting this 
   Could not find the ORIG_HANDLER or _HANDLER in the environment variables. This instrumentation requires the OpenTelemetry Lambda extension installed.
   
   and after adding that envi variables that error is gone but traces are not exporting and there is no logs related to otel aftyer adding that envi variable
