 For example:
 
 - Operational errors can happen when validation error is thrown by validating user input, it means that input body is incorrect and a `400 Bad Request` exception should be returned to the user with details of what fields are incorrect ([notification pattern](https://martinfowler.com/eaaDev/Notification.html)). In this case user can fix the input body and retry the request.
-- On the other hand, programmer error means something unexpected occurs in the program. For example, when exception happens on a new domain object creation, sometimes it can mean that an object is not used as intended and some rule is violated, for example a programmer did a mistake by assigning an incorrect value to a constructor, or value got mutated at some point and is no longer valid. In this case user cannot do anything to fix this, only a programmer can. In this case it may be more appropriate to throw a different type of exception that should be logged and then returned to the user as `500 Internal Server Error`, in this case without adding much additional details to the response since it may cause a leak of some sensitive data.
