Hi @shivanshu,

We are not aware, but please consider using the latest release of LocalStack which provides new version of Step Functions.

You can find details how to enable it in this article: LocalStack Release v2.3.0 - Announcement - LocalStack Discuss

We have introduced an all-new LocalStack-native StepFunctions provider, available behind a feature flag. You can activate it by setting PROVIDER_OVERRIDE_STEPFUNCTIONS=v2 in your LocalStack configuration.
