Summary

Changes

Please provide a summary of what's being changed

This PR fixes two problems with our Idempotency E2E tests:

• due to a breaking change in CDK, a Role was added to the stack that was not being deleted
• due to a bug handling integer keys, our Idempotency code was not working correctly

User experience

Please share what the user experience looks like before and after this change

After this change we should see the E2E tests passing more often.
