(assertions): incorrect validation error during GetLogEvents API call

[msambol]

Describe the bug

I don't believe this is a CDK issue, but I'm hoping this can be routed to the correct team.

I wrote an integration test and used the following code:

const message = putMessageOnQueue.next(test.assertions.awsApiCall('CloudWatchLogs', 'GetLogEvents', {
  LogGroupName: targetLogGroup.logGroupName,
  LogStreamName: logStreamName,
}));

I received the following error:

I tried both LogGroupName and LogGroupArn.

Expected Behavior

Log events to be returned

Current Behavior

ValidationException

Reproduction Steps

I wrote an integration test with the following code:

const targetLogGroup = new cdk.aws_logs.LogGroup(stack, 'TargetLogGroup');

const message = putMessageOnQueue.next(test.assertions.awsApiCall('CloudWatchLogs', 'GetLogEvents', {
  LogGroupName: targetLogGroup.logGroupName,
  LogStreamName: 'mylogstream',
}));

@msambol Good morning. Could you please share the self contained CDK code and packages used to reproduce the issue?

Thanks,
Ashish

@ashishdhingra – It happened while running this integration test: https://github.com/aws/aws-cdk/pull/30665/files#diff-2763bd6ad8e804e782f19c082f9eac5be850ff7e79b98407aaa86f999985ec3b.

@msambol Good afternoon. Thanks for sharing the input. Upon testing, looks like the parameter names for an API operation are case sensitive. If you refer GetLogEvents, the parameters logGroupName and logStreamName start with a lowercase letter.

One more problem in your code is that you are not creating Log Stream.

I was able to successfully deploy the below stack after making necessary changes:

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import { IntegTest } from '@aws-cdk/integ-tests-alpha';

const app = new cdk.App();
const stack = new cdk.Stack(app, 'aws-cdk-pipes-targets');

const test = new IntegTest(app, 'integtest-pipe-target-sqs', {
  testCases: [stack],
});

const sourceQueue = new cdk.aws_sqs.Queue(stack, 'SourceQueue');
const body = 'Cozumel';
const targetLogGroup = new cdk.aws_logs.LogGroup(stack, 'TargetLogGroup');
const logStreamName = 'Mexico';
const targetLogStream = new cdk.aws_logs.LogStream(stack, 'TargetLogStream', {
  logGroup: targetLogGroup,
  logStreamName: logStreamName
});

const putMessageOnQueue = test.assertions.awsApiCall('SQS', 'sendMessage', {
  QueueUrl: sourceQueue.queueUrl,
  MessageBody: body,
});

new cdk.CfnOutput(stack, 'logGroupName', { value: targetLogGroup.logGroupName});
const message = putMessageOnQueue.next(test.assertions.awsApiCall('CloudWatchLogs', 'getLogEvents', {
  logGroupName: targetLogGroup.logGroupName,
  logStreamName: logStreamName,
}));

cdk deploy --all output:
