(aws-logs): log retention failing cdk deployment with OperationAbortedException

What is the problem?

The LogRetention custom resource is causing CDK deployments to fail due to a race condition happening due to the log group the log retention is trying to create and the log group being created (and the retention period being set) for the log retention Lambda.

There was previously an issue made for this and a fix was completed and released, but many people are still reporting that the issue persists. The previous issue is here: https://github.com/aws/aws-cdk/issues/15709

Reproduction Steps

This is difficult to reproduce consistently, but the more a CDK app makes use of the LogRetention custom resource, the more likely it is to happen.

The RFDK integration tests (RFDK is a CDK construct library) deploy multiple stacks in parallel and have seen the failure on 7 of the last 10 runs.

What did you expect to happen?

We were expecting the CDK app to deploy successfully.

What actually happened?

The CDK app failed with the following error:

Other information

I modified the LogRetention Lambda to include a few more log statements and was able to reproduce the error. This is my modified createLogGroupSafe function:

var _a;

let retryCount = (options === null || options === void 0 ? void 0 : options.maxRetries) == undefined ? 10 : options.maxRetries;
console.log(`retryCount: ${retryCount}`); // DEBUGGING
const delay = ((_a = options === null || options === void 0 ? void 0 : options.retryOptions) === null || _a === void 0 ? void 0 : _a.base) == undefined ? 10 : options.retryOptions.base;
do {
    try {
        const cloudwatchlogs = new AWS.CloudWatchLogs({ apiVersion: '2014-03-28', region, ...options });
        await cloudwatchlogs.createLogGroup({ logGroupName }).promise();
        console.log(`LogGroup ${logGroupName} created successfully. Returning.`); // DEBUGGING
        return;
    }
    catch (error) {
        console.log('Caught error'); // DEBUGGING
        console.log(error); // DEBUGGING
        console.log(error.code); // DEBUGGING
        if (error.code === 'ResourceAlreadyExistsException') {
            // The log group is already created by the lambda execution
            console.log('ResourceAlreadyExistsException'); // DEBUGGING
            return;
        }
        if (error.code === 'OperationAbortedException') {
            console.log(`Caught OperationAbortedException. Retry: ${retryCount}`); // DEBUGGING
            if (retryCount > 0) {
                retryCount--;
                console.log(`Retrying with new retry count: ${retryCount}`); // DEBUGGING
                await new Promise(resolve => setTimeout(resolve, delay));
                continue;
            }
            else {
                console.log('Out of retry attempts'); // DEBUGGING
                // The log group is still being created by another execution but we are out of retries
                throw new Error('Out of attempts to create a logGroup');
            }
        }
        // Any other error
        console.error(error);
        throw error;
    }
} while (true); // exit happens on retry count check

This produced the following log:

From this we can see that:

1. It created the initial log it was trying to create successfully.
2. It hit a ResourceAlreadyExistsException, likely when trying to create the LogGroup for the Lambda itself, which is expected if the Lambda has previously ran.
3. After that, it goes right to an OperationAbortedException without hitting the Caught error logging line I added or flowing through any of the retry logic.

I believe this logging would indicate that the OperationAbortedException might not be coming from createLogGroupSafe and might instead be coming from setRetentionPolicy that happens after.

Could the speed of the machine CDK is running on manifest this ? We have works on my machine when running CDK from developer’s mac books, but failure when running CDK through Github actions

Still occurs as of v1.136.0
