Cannot use the extras lambda layer

[FredrikMeyer]

I'm trying to use the extras layer, but I get a error message:

[ERROR] Runtime.ImportModuleError: Unable to import module 'main': No module named 'pydantic'

Expected Behavior

Be able to import the parser module without also installing pydantic.

Current Behavior

Pydantic is not included in the layer.

Steps to Reproduce (for bugs)

My SAM template:

  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: ./my_function
      Handler: main.handler
      Runtime: python3.8
      Layers:
        - !GetAtt AwsLambdaPowertoolsPythonLayer.Outputs.LayerVersionArn

  AwsLambdaPowertoolsPythonLayer:
    Type: AWS::Serverless::Application
    Properties:
      Location:
        ApplicationId: arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer-extras
        SemanticVersion: 1.10.3

Environment

Deployed via

sam build --use-container && sam deploy  --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND 

I've downloaded the layer to my machine and I double-checked that pydantic is not included.

Thanks for the report @FredrikMeyer. I can confirm the published layer doesn't contain the correct dependencies. I've fixed an issue in our pipeline that I think was causing this, so future releases of powertools should get all the correct dependencies packaged with the layer. Looking into how/if we can fix this for already deployed layer versions.

[to-mc]

I've made a new release (1.10.4) to trigger the fixed pipeline to publish a new layer version. The published versions are immutable so we can't replace those. Should work fine after updating SemanticVersion to 1.10.4.

Thank you for the quick answer and solution! I've just confirmed that the new release works.
