Unexpected cyclic reference error with lambda.addEventSource

I tried to split into two stacks. One creates S3 Bucket, and the other creates a lambda and add event source to that from s3 of other stack. When execute cdk deploy, error messages put on console.

Reproduction Steps

source Code

import cdk = require( '@aws-cdk/core' )
import * as S3 from '@aws-cdk/aws-s3';
import * as Lambda from '@aws-cdk/aws-lambda';
import { S3EventSource } from '@aws-cdk/aws-lambda-event-sources';

const app = new cdk.App();

export class Stack1 extends cdk.Stack {
  readonly bucket: S3.Bucket;
  constructor( scope: cdk.Construct, name: string, props?: cdk.StackProps ) {
    super( scope, name, props );

    this.bucket = new S3.Bucket( this, 'tests3' );
  }
}

interface Stack2Props extends cdk.StackProps {
  bucket: S3.Bucket
}
export class Stack2 extends cdk.Stack {

  constructor( scope: cdk.Construct, name: string, props: Stack2Props ) {
    super( scope, name, props );
    const lambda = new Lambda.Function(
      this,
      'testLambda',
      {
        functionName: 'test',
        code: Lambda.Code.fromAsset( { ***source path***} ),
        handler: 'index.handler',
        runtime: Lambda.Runtime.NODEJS_8_10,
      }
    );
    lambda.addEventSource(
      new S3EventSource( props.bucket, {
        events: [S3.EventType.OBJECT_CREATED],
      } )
    );
  }
}

const stack1 = new Stack1( app, 'stack1' );
const stack2 = new Stack2( app, 'stack2', {
  bucket: stack1.bucket
} );

app.synth();

Error Log

$ ENV=dev cdk deploy
'stack2' depends on 'stack1' (stack2 -> stack1/tests3/Resource.Arn). Adding this dependency (stack1 -> stack2/testLambda/Resource.Arn) would create a cyclic reference.

Environment

• CLI Version : 1.14.0
• Framework Version:1.14.0
• OS :Mac

This is 🐛 Bug Report

I want to keep this issue open. Currently I keep both s3 and lambda resources in a single stack to avoid the cyclic reference.

I’d like to separate global from regional resources. Also I’d like to keep my resources in a single app.

So even if I am importing the bucket (not the name or ARN) into the stack, the below seems to do the trick.

Stack 1 - Creates mybucket. Stack 2 - Imports it as a shared resources props.mybucket

In Stack 2 instead of using props.mybucket directly in the addEventSource, I do this-

const myBucket = s3.Bucket.fromBucketName(this, 'temp-my-bkt', props.mybucket.bucketName)
        
lambdaFn.addEventSource(new S3EventSource(inputIDPBucket, {
            events: [s3.EventType.OBJECT_CREATED],
            filters: [{ prefix: 'myprefix/'}]
}));
