Hi, @angelbn01 pay attention when you use the annotations NotBlank and NotNull;

In Hibernate, @notblank is typically used to validate that a String field is not null and has some non-whitespace characters. It's primarily intended for String fields, and it won't directly work for integer fields.
However, for validating integer fields, you can use other validation annotations such as NotNull, Min, Max, etc., depending on your specific validation requirements.

Changed also the type Int to Long in the Id variable
