cloud-assembly-schema: MetadataEntryData type missing boolean | number

[matusfaro]

Describe the bug

Bumping to latest dependencies and going from cloud schema 36.0.0 to 38.0.1, I get the following error:

[ERROR] Failed to execute goal io.dataspray:aws-cdk-maven-plugin:2.3.1-SNAPSHOT:synth (run-cdk-synth) on project dataspray-package:

Notice that the data type is expected to be string | aws-cdk-lib.cloud_assembly_schema.FileAssetMetadataEntry | aws-cdk-lib.cloud_assembly_schema.ContainerImageAssetMetadataEntry | array<aws-cdk-lib.cloud_assembly_schema.Tag> | undefined.

This is because as part of the change introduced here:

expr.directCode(`this.addMetadata('${CUSTOM_RESOURCE_SINGLETON}', true)`),
expr.directCode(`this.addMetadata('${CUSTOM_RESOURCE_RUNTIME_FAMILY}', this.runtime.family)`),

The value of the data field may now be a number and boolean. But the type defined in cloud schema MetadataEntryType is not updated with these types here

export type MetadataEntryData =
  | AssetMetadataEntry // FileAssetMetadataEntry | ContainerImageAssetMetadataEntry
  | LogMessageMetadataEntry // string
  | LogicalIdMetadataEntry // string
  | StackTagsMetadataEntry; // Tag[]

Notice these are the types from the error message.

Below is a snippet of the generated manifest.json with this issue:

...
        "/dataspray-site-landing-test/Custom::CDKBucketDeployment8693BB64968944B69AAFB0CC9EB8756C": [
          {
            "type": "aws:cdk:is-custom-resource-handler-singleton",
            "data": true
          },
          {
            "type": "aws:cdk:is-custom-resource-handler-runtime-family",
            "data": 2
          },
          {
            "type": "aws:cdk:is-custom-resource-handler-singleton",
            "data": true
          },
          {
            "type": "aws:cdk:is-custom-resource-handler-runtime-family",
            "data": 2
          }
        ],
...

Note that aws:cdk:is-custom-resource-handler-singleton matches the CUSTOM_RESOURCE_SINGLETON above and aws:cdk:is-custom-resource-handler-runtime-family matches the CUSTOM_RESOURCE_RUNTIME_FAMILY above.

Regression Issue

• Select this option if this issue appears to be a regression.

Last Known Working CDK Version

CDK 2.134.0 Cloud Assembly 36.0.6

Expected Behavior

Shouldn't fail. Expected the generated manifest.json to be read properly.

Current Behavior

Fails with error.

Reproduction Steps

It's difficult to create a self-contained snippet for reproduction. It's unclear to me what conditions are met for the metadata entries to be generated.

Possible Solution

Add missing types to MetadataEntryData

@matusfaro Good morning. Thanks for opening the issue. You mentioned that the issue was likely introduced as part of the change introduced here. This change was made 5 months ago, but we haven't got any reports of regression until now. By definition of potential regression, the issue should likely be introduced in recently released version of CDK, which was working in last (or may be few versions, let's day 4-5 versions, in the past). Please share the CDK (CLI and Lib) version used.

In order to reproduce the issue, please share the minimal self contained CDK code that reproduces the issue and demonstrates upgrading cloud schema from 36.0.0 to 38.0.1. I will try to investigate the issue further as much as possible.

Thanks,
Ashish

Hi @ashishdhingra

Here's a simple self-contained repro in Groovy.

Honestly I am not sure why I am the first one to hit this, it could be for a combination of reasons:

• Manifest.loadAssemblyManifest is not typical usage, I'm using it as part of tooling around CDK for a Maven plugin
• The specific conditions that create the unsupported value could be rare.
• It may be specific to Java/JVM languages only

@matusfaro Good afternoon. Thanks for sharing the code. Ignoring details about language used (Groovy in your case), this appears to be JSII issue.

• Tried testing using TypeScript and it appears to work fine.

TypeScript example

lib/cdktest-stack-new.ts

import * as cdk from 'aws-cdk-lib';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3deployment from 'aws-cdk-lib/aws-s3-deployment';

export class CdktestStackNew extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const destinationBucket = new s3.Bucket(this, 'MyBucket', {
      removalPolicy: cdk.RemovalPolicy.DESTROY
    });

    new s3deployment.BucketDeployment(this, 'MyBucketDeployment', {
      sources: [],
      destinationBucket: destinationBucket
    });
  }
}

bin/cdktest.ts

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import { CdktestStackNew } from '../lib/cdktest-stack-new';
import * as fs from 'fs';
import * as cloudAssemblySchema from '@aws-cdk/cloud-assembly-schema';

const app = new cdk.App();

new CdktestStackNew(app, 'CdktestStackNew', {
  env: { account: process.env.CDK_DEFAULT_ACCOUNT, region: process.env.CDK_DEFAULT_REGION },
});

const assembly = app.synth();

const manifestPath = `${assembly.directory}/manifest.json`;
console.log(`manifestPath: ${manifestPath}`);

const manifestFile = fs.readFile(manifestPath, { encoding: 'utf-8'}, (err, data) => {
  if (err) throw err;
  console.log(data);
});

const assemblyLoaded = cloudAssemblySchema.Manifest.loadAssemblyManifest(manifestPath);
console.log(`assemblyLoaded.version: ${assemblyLoaded.version}`);

• Tried testing using Java and it fails.
  • First used built in AssemblyManifest and Manifest classes from software.amazon.awscdk.cloud_assembly_schema namespace in aws-cdk-lib (customer's scenario).
  • Then used from software.amazon.awscdk.cloudassembly.schema in cdk-cloud-assembly-schema version 39.1.38.

cdklabs/cloud-assembly-schema was migrated from main CDK repo as separate repo, starting from version 39.0.1 (refer commit history) in June 2024.

If we use software.amazon.awscdk.aws-cdk-lib package version 2.134.0, not using software.amazon.awscdk.cdk-cloud-assembly-schema (modify pom.xml accordingly and refresh packages), the above synthesis work fine.

Transferring to JSII repo.

Thanks,
