(stepfunctions): CDK generated stepfunction roles breaking inflight stepfunction executions with versioned lambdas #17515

Description

What is the problem?

Using stepfunction auto generate of stepfunction roles and also use versioned lambdas in the step functions. On deployment, the stepfunction role is updated with the new lambda version. This causes invoke:lambda role failures in in-flight stepfunction executions as they will have the previous lambda version in their stepfunction execution definition but will now have the newer lambda version in the stepfunction role.

Is there way to have stepfunction auto generated roles to not include the lambda version in the role?

Reproduction Steps

Create a stepfunction that invokes a lambda version. The stepfunction role will contain a lambda version

What did you expect to happen?

Stepfunctions to not fail on inflight executions during a deployment

What actually happened?

Stepfunction lambda:invoke errors on mismatched lambda versions:
Error
