(aws-cdk-lib): (NodejsFunction & NestedStack)

[TirushV]

Describe the bug

When deploying NestedStack with NodejsFunction construct the entry of lambda function is actually taking wrong file. Its bundling the root folder of CDK and then trying to upload this on Lambda function (nodejs). This issue is open since 2 years (2022). Expecting it to be deployed with right entry point path file with nested stack.

REFER THIS OLD ISSUE - [#23181](https://github.com/aws/aws-cdk/issues/23181)

Expected Behavior

NodejsFunction should be deployed with correct entry file with NESTED STACK instead of bundling cdk root folder. (which is a very large file and fails due to this)

Current Behavior

Resource handler returned message: "Unzipped size must be smaller than 262144000 bytes (Service: Lambda, Status Code: 400, Request ID: 8a550035-ac30-4f04-8e5a-95ecf6e5b809)" (RequestToken: 4ed9ea28-2951-f1d3-232a-51a21ee23e53, HandlerErrorCode: InvalidRequest), Resource handler returned message: "Unzipped size must be smaller than 262144000 bytes

Reproduction Steps

Bin file

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as s3 from 'aws-cdk-lib/aws-s3';
import { NestStack } from '../lib/nest-stack';

const app = new cdk.App();

interface stackProps {
  i: number;
}

export class FirstStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props: stackProps) {
      super(scope, id);

      const { i } = props;
 
      for (let k = 0; k < props.i; k++) {
        new NestStack(this, `NestStack${k}`);
      }
  }
}
new FirstStack(app, 'TestStack', { i: 4 }); 

Nested stack file

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { NodejsFunction } from 'aws-cdk-lib/aws-lambda-nodejs'
import { Runtime } from 'aws-cdk-lib/aws-lambda'
import * as path from 'path'

export class NestStack extends cdk.Stack {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    const lambdaAppDir = path.resolve(__dirname, '../lambda')

    const fn = new NodejsFunction(this, `function`, {
      functionName: 'test-function',
      runtime: Runtime.NODEJS_16_X,
      timeout: cdk.Duration.seconds(10),
      memorySize: 128,
      entry: path.join(lambdaAppDir, 'index.ts'),
    })
  }
}

Hello @khushail , Appreciate the help here.

[khushail]

@TirushV , thanks for reaching out. Looks like you are deploying with an old version . Could you please try using the latest cdk version 2.147.0 and share updates if it still persists?

[TirushV]

@khushail Tried (2.147.1 (build d3695d4)) that but no luck

node:internal/errors:491
    ErrorCaptureStackTrace(err);

}

Node.js v18.13.0

It seems that cdk is bundling the whole root folder instead of lambda entry file. That the bug

[khushail]

Hey @TirushV , I tried to repro the issue as mentioned by you but did not see anything happening as such.

Could you please share more details I might be missing in reproduction of the issue ? where should I see the zipped package ?

[TirushV]

Could you share the code snippet you tried? also which aws-cdk-lib version you had used. With the above code snippet when i try running the command - cdk deploy . Getting above error. Please let me know what details are required.

Main issue is its not zipping the file. Its trying to zip the whole cdk root folder.

@TirushV Good afternoon. Somehow, I'm unable to reproduce the issue. Below is the TypeScript CDK code:
/lambda/index.ts

exports.handler = async function() {
  return {
    statusCode: 200,
    headers: { "Content-Type": "text/plain" },
    body: 'Hello, CDK!'
  };
};

/lib/NestedStack.ts

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { NodejsFunction } from 'aws-cdk-lib/aws-lambda-nodejs';
import { Runtime, Architecture } from 'aws-cdk-lib/aws-lambda';
import * as path from 'path';

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

    const lambdaAppDir = path.resolve(__dirname, '../lambda');

    const fn = new NodejsFunction(this, `function`, {
      functionName: 'test-function',
      runtime: Runtime.NODEJS_16_X,
      timeout: cdk.Duration.seconds(10),
      memorySize: 128,
      architecture: Architecture.ARM_64,   // Used ARM_64 since running CDK Deploy on Apple M1 MacBook Pro
      entry: path.join(lambdaAppDir, 'index.ts'),
    });
  }
}

/bin/issue30627.ts

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { NestStack } from '../lib/NestStack';

const app = new cdk.App();

interface stackProps {
  i: number;
}

export class FirstStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props: stackProps) {
      super(scope, id);

      const { i } = props;
 
      for (let k = 0; k < props.i; k++) {
        new NestStack(this, `NestStack${k}`);
      }
  }
}

new FirstStack(app, 'TestStack', { i: 4 });

Kindly note that in above code:

• Architecture is set as Architecture.ARM_64 for Lambda function created in nested stack since the scenario is being run on Apple M1 Macbook Pro.
• Lambda handler is pretty minimalistic. If you are using some complex logic that references some external module, then it might increase the Lambda deployment size.

Running cdk deploy --all produces the below output:

The error above is different since there is already a function named test-function in first created nested stack. So your logic needs to be modified to create 4 different distinct Lambda functions, may be based on some identifier in custom cdk.StackProps for nested stack and using that identifier while setting function name.

If the issue still persists at your end, kindly share the minimal code solution (excluding the cdk.out and node_modules directory) to troubleshoot further.

Thanks,
Ashish
