pip install cdk-secret-manager-wrapper-layer

Common errors

error ModuleNotFoundError: No module named 'cdk_secret_manager_wrapper_layer' ↓

cause Package not installed in the current environment.

fix

Run 'pip install cdk-secret-manager-wrapper-layer' in your environment.

error AttributeError: module 'cdk_secret_manager_wrapper_layer' has no attribute 'SecretManagerWrapperLayer' ↓

cause Using an outdated import path or wrong class name.

fix

Use correct import: 'from cdk_secret_manager_wrapper_layer import SecretManagerWrapperLayer'

error jsii.errors.JSIIError: ... does not exist in ... ↓

cause Mismatch between CDK version and layer version (CDK v1 vs v2).

fix

Ensure you are using aws-cdk-lib (CDK v2) with version 2.x of the construct.

Warnings

breaking Version 2.x switched to AWS CDK v2. If upgrading from 1.x, you must migrate your CDK app to CDK v2. ↓

fix Use aws-cdk-lib instead of @aws-cdk/ packages. Update your CDK app to v2.

deprecated The construct name 'SecretManagerWrapper' (without 'Layer') was used in early versions and is now deprecated. Use 'SecretManagerWrapperLayer' instead. ↓

fix Replace deprecated construct with SecretManagerWrapperLayer.

gotcha The layer is intended for Python 3.9 Lambda runtimes. Using other runtimes may cause incompatibility. ↓

fix Ensure your Lambda function uses Python 3.9 runtime.

Imports

SecretManagerWrapperLayer

wrong

from cdk_secret_manager_wrapper_layer.secret_manager_wrapper_layer import SecretManagerWrapperLayer

correct

from cdk_secret_manager_wrapper_layer import SecretManagerWrapperLayer

Older docs or examples may show deeper nesting; the top-level import is correct.

Quickstart

Minimal CDK app to deploy the Lambda layer.

from aws_cdk import App, Stack
from cdk_secret_manager_wrapper_layer import SecretManagerWrapperLayer

app = App()
stack = Stack(app, 'TestStack', env={'region': 'us-east-1'})
SecretManagerWrapperLayer(stack, 'MyLayer')
app.synth()
