AI Summary: The patient update endpoint in the Spring Boot application throws a 500 Internal Server Error when the `email` field is omitted from the request body. The issue stems from a `@NotNull` constraint on the `email` field in the `Patient` entity. The task is to modify the application to handle the case where `email` is absent, either by making the `email` field nullable in the database and entity, or by implementing appropriate validation and error handling to return a more user-friendly error message instead of a 500 error.
