go.mod file 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. |

v1.105.0 It was released last month, could you try bump it in your sample project and retest? and again i'm not entirely sure if it the issue, so would be good to confirm |

@ashishdhingra we downgraded to 1.0.4 and still getting the same error. panic: JsiiError: @jsii/kernel.Fault Module '@aws-cdk/aws-lambda-python-alpha' not found |

@ashishdhingra Apologise again for another message - but i come with good news - a reproducible minimal example. https://github.com/kaykhan/aws-lambda-python-alpha-kernal-fault-jsii The issue occurs when introducing the Why is the above is causing a kernal fault and preventing the awscdklambdapythonalpha.NewPythonFunction is the main issue as the hooks themselves work correctly. Please do test and confirm the bug and get back to us. |
@kaykhan Good morning. Thanks for opening the issue. This issue was initially reported when using Using your sample minimal reproducible code from https://github.com/kaykhan/aws-lambda-python-alpha-kernal-fault-jsii Notice your

@ashishdhingra Please use the command in my instructions so that it targets the exact application and does not target the default one - The issue is a conflict when using both @aws-cdk/aws-lambda-go-alpha @aws-cdk/aws-lambda-python-alpha in the same application where @aws-cdk/aws-lambda-go-alpha is using a CommandHook during bundling. |
