Deployment:

$ awslocal cloudformation deploy --stack-name lm-test --template-file modules-test-templates/test-module-cloudformation-alb-v1.0.0.yaml

Waiting for changeset to be created..
Waiting for stack create/update to complete

Failed to create/update the stack. Run the following command
to fetch the list of events leading up to the failure
aws cloudformation describe-stack-events --stack-name lm-test

Deployed stakcs:

$ awslocal cloudformation list-stacks --query "StackSummaries[].StackId" | grep lm
    "arn:aws:cloudformation:eu-west-1:000000000000:stack/lm-test/c6f89e25",
    "arn:aws:cloudformation:eu-west-1:000000000000:stack/lm-test-LoadBalancer-ef50c545/86ddbbe4"

We delete the failed parent stack:

$ awslocal cloudformation delete-stack --stack-name lm-test

$ awslocal cloudformation describe-stacks --stack-name arn:aws:cloudformation:eu-west-1:000000000000:stack/lm-test/c6f89e25

Nested stack still in ROLLBACK_COMPLETE state:

$ awslocal cloudformation describe-stacks --stack-name arn:aws:cloudformation:eu-west-1:000000000000:st

            }
        }
    ]
}

Expected Behavior

Nested stack to be deleted along the parent stack.

How are you starting LocalStack?

With the localstack script

Steps To Reproduce

How are you starting localstack (e.g., bin/localstack command, arguments, or docker-compose.yml)

docker run \
--rm \
--name localstack-main \
-p 4566:4566 \
-p 4510-4559:4510-4559 \
-e LOCALSTACK_AUTH_TOKEN="$LOCALSTACK_AUTH_TOKEN" \
-e LS_LOG=DEBUG  \
-e POD_LOAD_CLI_TIMEOUT=3000 \
-v /var/run/docker.sock:/var/run/docker.sock \
localstack/localstack-pro:3.4.0

Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

awslocal cloudformation delete-stack --stack-name lm-test

Environment

- OS: 5.15.146.1-microsoft-standard-WSL2
- LocalStack: 3.4.1.dev20240425063645:c7494f2
