[@aws-cdk/aws-lambda-event-sources] Add Lambda as event source in SQS producing Error

[niciqy]

I am trying out with the example found in CDK site. Essentially, it trying to add a lambda as event source to SQS

import * as sqs from '@aws-cdk/aws-sqs';
import { SqsEventSource } from '@aws-cdk/aws-lambda-event-sources';
import { Duration } from '@aws-cdk/core';

const queue = new sqs.Queue(this, 'MyQueue', {
  visibilityTimeout: Duration.seconds(30)      // default,
  receiveMessageWaitTime: Duration.seconds(20) // default
});

lambda.addEventSource(new SqsEventSource(queue, {
  batchSize: 10 // default
});

I am getting this error:
Argument of type 'SqsEventSource' is not assignable to parameter of type 'IEventSource'. Types of property 'bind' are incompatible.

Environment

• CLI Version 1.57.0:
• Framework Version:
• Node.js Version: v10.16.3
• OS : OSX 10.14.3
• Language (Version): TypeScript (3.8.3)

How are we tracking with this issue? Is this a me issue are other people having the same problem?

This is likely because the version of aws-lambda-event-sources is not the same as aws-lambda. Can you check the version of these packages (either in yarn.lock or package-lock.json`) and ensure they are exactly same?
