Error creating Chart with aws-cdk Construct scope

[Hazzard17h]

I'm creating a cdk8s Chart in an aws-cdk project, using the following dependencies versions:

"aws-cdk-lib": "^2.0.0",
"cdk8s": "^2.0.0",
"constructs": "^10.0.0",

Using an aws-cdk Construct as the parent scope for the Chart, I'm getting: 'Error: cannot find a parent chart (directly or indirectly)'

import { Construct } from 'constructs';
import { App as AwsApp, Stack } from 'aws-cdk-lib';
import { Cluster, KubernetesVersion } from 'aws-cdk-lib/aws-eks';
import { App as K8sApp, Chart } from 'cdk8s';

class MyStack extends Stack {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    const cluster = new Cluster(this, 'Cluster', { version: KubernetesVersion.V1_21 });

    cluster.addCdk8sChart('Test1', new Chart(this, 'Test1')); // <--- NOT WORKS
    cluster.addCdk8sChart('Test2', new Chart(new K8sApp(), 'Test2')); // <--- WORKS
  }
}

new MyStack(new AwsApp(), 'MyStack');

Which is the intent of Ecosystem Interoperability if the parent scope of a cdk8s Construct can't be an aws-cdk Construct?

@Hazzard17h Yeah, currently passing in an AWS CDK construct as the scope will not work.

I agree this is a bit confusing with regards to interop. There are many levels to that interop support.

• The first was to even make it possible to use the two CDK's in the same App.
• The second was to allow passing tokens between the two.
• The third is to allow common scopes.

We unfortunately still haven't reached level 3.
