Status: RESOLVED

Overview:

The latest CDK release (https://github.com/aws/aws-cdk/releases/tag/v2.161.0) appears to have reintroduced #27526.

Intermittently when deploying the following error is printed.

Complete Error Message:

The last time this issue was present was because the describeStackEvents was called with { stackName: '' }. #27526 (comment). This recent PR #31407 touched the area of code that caused the previous issue.

Workaround:

Pin CDK version to 2.160.0

Last Known Working CDK Version

v2.160.0

Expected Behavior

The monitoring behavior should not attempt to describe a stack without providing the stack name.

Current Behavior

See error message above. The issue is intermittent.

Reproduction Steps

I am reliable reproducing the error when using Amplify Gen 2 (which under the hood uses the Amplify GraphQL API construct).

mkdir cdkmonitoringbug
cd cdkmonitoringbug
npm create amplify@latest
npx ampx sandbox 

The error message should show after this. If does not, try npx ampx sandbox delete and then npx ampx sandbox.

I haven't tested this yet, but the following guide would probably lead to the error as well. https://aws.amazon.com/blogs/mobile/announcing-aws-amplifys-graphql-api-cdk-construct-deploy-real-time-graphql-api-and-data-stack-on-aws/
