Error with new shared asset bundler

[QuinnGT]

App version: 3.1.5
Error message: Error: Bundling did not produce any output. Check that content is written to /asset-output.

Findings:

1. I tried making a slight change to the docker build and the build works

    bundleWithAsset(assetPath: string): Asset {
        const asset = new aws_s3_assets.Asset(this, md5hash(assetPath).slice(0, 6), {
            path: assetPath,
            bundling: {
                image: DockerImage.fromBuild(path.join(__dirname, 'alpine-zip')),
                command: [
                    "sh", "-c",
                    "zip -r /asset-output/lambda.zip . && ls /asset-output"  // Added ls command for debugging
                ],
                volumes: this.sharedAssets.map(f => ({
                        containerPath: path.join(this.WORKING_PATH, path.basename(f)),
                        hostPath: f
                    })),
                workingDirectory: this.WORKING_PATH,
                outputType: BundlingOutput.ARCHIVED,
            }
        });
        return asset;
    }

However, once live on lambda I get a 400 error on the function GenAIChatBotStack-LangchainInterfaceRequestHand. Looking at the trace I see the message Unable to import module 'index': No module named 'genai_core' So pretty sure my change is getting the docker container to build but somehow missing the lib\shared\layers\python-sdk\python\genai_core

2. I noticed the lambda.zip is showing up under lib\rag-engines\aurora-pgvector\functions\pgvector-setup after running npx cdk deploy.

Can't seem to figure it out yet but I'll keep trying. Any help would be appreciated.

@massi-ang just an fyi in case you haven't seen this issue but I'm unable to do a fresh build on the 3.1.5 release or the new release. It's really this error Error: Bundling did not produce any output. Check that content is written to /asset-output. as the cdk is creating a file here aws-genai-llm-chatbot\lib\rag-engines\opensearch-vector\functions\create-workflow\create\asset-outputasset.zip.

Is the build working for you and others or is there some new config I need to do?

Just figured out it's due to the unix style path and I'm trying to deploy via powershell in vscode on windows. Deploy worked fine on my mac, so I'll work from that from now on but a cross-platform path with something like path.normalize() would be ideal.

Found the error here aws/aws-cdk#19270. Testing the fix now.
