(@aws-cdk/pipelines): CdkPipeline assets & DynamoDB with replicationRegions

[adamskicool]

When using the construct CdkPipeline to deploy a stack that creates a global dynamo table using replicationRegions, not all assets seem to be included in the assets stage of the pipeline. When synthesizing the pipeline, four assets seem to be connected to the stack (see below, copy pasted from cdk-out/assembly-{the-stack-name}). When I look at the pipelines assets (after having deployed the CdkPipeline) and go into their details I can see that there are only three of four assets included in the assets step, that is the last asset that looks like it contains a template is excluded (c58ee6d7fc2dd16161745b02f0d7220f4da730b163cdb57e3818cf4333515500)

Reproduction Steps

Create a CdkPipeline with one stage containing one stack that creates a global DynamoDB table

Stage:

import {
  Stage,
  Construct,
  StageProps,
} from "@aws-cdk/core";
import { StorageStack } from "../storage";

export class StorageStage extends Stage {
  constructor(
    scope: Construct,
    id: string,
    props?: StageProps
  ) {
    super(scope, id, props);

    new StorageStack(
      this,
      "storage-stack"
    );
  }
}

The stack the stage creates:

import {
  Construct,
  Stack,
  StackProps,
} from "@aws-cdk/core";
import {
  AttributeType,
  Table,
} from "@aws-cdk/aws-dynamodb";

export class StorageStack extends Stack {
  constructor(
    scope: Construct,
    id: string,
    props?: StackProps
  ) {
    super(scope, id, props);

    const replicationRegions: string[] = [
      "us-west-2",
    ];

    new Table(this, "Table", {
      partitionKey: {
        name: "id",
        type: AttributeType.STRING,
      },
      replicationRegions,
    });
  }
}

What did you expect to happen?

I expected the CodePipeline asset step to include all assets that the stack it is deploying contains.

What actually happened?

Includes all but one asset.

@adamskicool This is the intended behavior. The pipeline deploys all assets, but excludes the stack template itself, which is the artifact that you noticed is missing.
