[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'aws_xray_sdk'

Hi,

I am using AWS Codestar to develop a python lambda function.

I added X-Ray support following https://docs.aws.amazon.com/codestar/latest/userguide/customize-project-xray.html and added pip install aws-xray-sdk to my buildspec.yml

# Upgrade AWS CLI to the latest version
- pip install --upgrade awscli

# Upgrade AWS X-Ray SDK
- pip install --upgrade aws-xray-sdk

Add instrumented my code as per https://docs.aws.amazon.com/lambda/latest/dg/python-tracing.html.

But CloudWatch Logs always show this error.

There is no requirements.txt by default in CodeStar projects. What is missing here?

Inizia da buildspec.yml e ispeziona l’artefatto Lambda distribuito per verificare se aws_xray_sdk è incluso insieme al codice della funzione. Confronta i passaggi di packaging con le guide collegate su AWS CodeStar e il tracing di Lambda; il lavoro è completato quando la funzione distribuita importa l’SDK senza che si verifichi Runtime.ImportModuleError.

Scritto dal modello di indicizzazione a partire dal testo della issue.
