Error while creating custom resource trigger for lambda

I created a lambda via ts file with the following specifications:

        description: 'Lambda request handler to automate the DDL commands',
        name: LAMBDA_NAME,
        timeout: Duration.minutes(10),
        memorySize: 512,
        componentName: 'DdlLambda',
        runtime: Runtime.JAVA_11,
        handler: 'handler.ddllambda',
        packageName: 'DDLManagementLambda-1.0',
        deadLetterQueueEnabled: false,
        tracing: Tracing.ACTIVE,
        profiling: false,
        logRetention: RetentionDays.FOUR_MONTHS

Created a custom resource with

import {CustomResource} from "monocdk";

const customResource = new CustomResource(this, 'CustomResource', {
  serviceToken: ddllambda.functionArn,
  properties: {
      version: "version_0"
  }

But I am getting the error

CloudFormation did not receive a response from your Custom Resource. 
Please check your logs for requestId [c634da01-9c4d-4f8e-a2fc-a28724aa8206]. 
If you are using the Python cfn-response module, you may need to update your 
Lambda function code so that CloudFormation can attach the updated version.

I am not able to find the logs for the given requestId. What am I missing here?

Solution

  • I was not sending the response back from lambda, hence was getting the error. Referring this code helped https://github.com/stelligent/cloudformation-custom-resources/blob/master/lambda/java/src/main/java/com/stelligent/customresource/CustomResourceHandler.java.
