Getting null pointer exception on java.lang.String moe.banana.jsonapi2.JsonApi.type() #37

I have Contact class with type="contacts" @JsonApi(type = "contacts") public class Contact extends Resource implements Serializable { }

But now I am creating an object of class which is sub-class of Contact. But, I am getting following error,

12-01 13:54:55.641 27318-27318/vocera.uc E/CoreApplication: Uncaught Exception java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.String moe.banana.jsonapi2.JsonApi.type()' on a null object reference at moe.banana.jsonapi2.Resource.typeNameOf(Resource.java:426) at moe.banana.jsonapi2.Resource.(Resource.java:155) At Vocera. Ac. core. entity_model. Contact.(Contact.java:14)

I am doing something wrong here? Do I need to add same @JsonApi(type = "contacts") to sub-class also?

A @JsonApi annotation is not inheritable. When you have multiple instance of the same type, the annotation should be declared on each of the class. But be cautious this may not be the best practice of JSON API specification.
