core: CLI --hotswap -> We don't support attributes of the 'AWS::Cognito::UserPool' resource.

[louislatreille]

Describe the bug

I have a stack that has a nested stack

The parent stack instantiate many resources, including a Cognito UserPool. The nested stack has only Lambda function, which use some attributes of the UserPool. When deploying and using the hotswap option, the deployment fails.

Expected Behavior

I expect the hotswap option to succeed, and successfully deploy the lambda functions in my nested stack.

Current Behavior

I get the following error:

Could not perform a hotswap deployment, because the CloudFormation template could not be resolved: We don't support attributes of the 'AWS::Cognito::UserPool' resource. This is a CDK limitation. Please report it at https://github.com/aws/aws-cdk/issues/new/choose

Reproduction Steps

bin/index.ts

#!/usr/bin/env node
import { App } from "aws-cdk-lib";
import "source-map-support/register";
import { StackOne } from "./test";

const app = new App();

const test = new StackOne(app, "my-stack", { env: { region: "<region>", account: "<account>" } });

lib/index.ts

import { NestedStack, NestedStackProps, Stack, StackProps } from "aws-cdk-lib";
import { Construct } from "constructs";
import { UserPool, StringAttribute } from "aws-cdk-lib/aws-cognito";
import { NodejsFunction } from "aws-cdk-lib/aws-lambda-nodejs";

type Props = NestedStackProps & {
  userPoolId: string;
  userPoolArn: string;
};

export class StackTwo extends NestedStack {
  constructor(scope: Construct, id: string, props: Props) {
    super(scope, id, props);

    new NodejsFunction(this, "my-lambda", {
      entry: "./test/handler.ts",
      handler: "main",
      environment: {
        POOL_ID: props.userPoolId,
        POOL_ARN: props.userPoolArn,
      },
    });
  }
}

export class StackOne extends Stack {
  constructor(scope: Construct, id: string, props: StackProps) {
    super(scope, id, {
      ...props,
    });

    const userPool = new UserPool(this, "test-userpool", {
      userPoolName: "test-userpool",
      signInCaseSensitive: false, // case insensitive is preferred in most situations
      selfSignUpEnabled: true,
      standardAttributes: {
        preferredUsername: {
          mutable: true,
          required: true,
        },
      },
      customAttributes: {
        appUsername: new StringAttribute({ minLen: 3, maxLen: 20, mutable: true }),
      },
      signInAliases: { email: true },
      autoVerify: { email: true },
    });

    new StackTwo(this, "my-stack-two", {
      userPoolArn: userPool.userPoolArn,
      userPoolId: userPool.userPoolId,
    });
  }
}
