Describe the bug

I want to deploy a python function using https://docs.aws.amazon.com/cdk/api/v2/docs/aws-lambda-python-alpha-readme.html

However i get the error panic: JsiiError: @jsii/kernel.Fault Module '@aws-cdk/aws-lambda-python-alpha' not found
when i run any cdk command.

I installed using.

go get -u github.com/aws/aws-cdk-go/awscdklambdapythonalpha/v2

I am using github.com/aws/aws-cdk-go/awscdklambdapythonalpha/v2 v2.173.1-alpha.0

I wonder if it has something to do with the github.com/aws/jsii-runtime-go version update with aws-cdk?

unforutantly im not able to donwgrade to version github.com/aws/jsii-runtime-go v1.104.0 like you have in yours as it looks like there is a dependent project relying on the newest v1.105.0

@kaykhan Assuming if this is the case, please wait for sometime before trying again. As packages for different languages are released, it might take some time for package managers to get updated.
