Java.lang.IllegalArgumentException: невозможно создать адаптер вызова для модернизации интерфейса.Call ⇐ JAVA

[Гость]

Код в моем VSApiEndpointInterface

Код: Выделить всё

@POST(REGISTER_USER)
Call registerUser(@Body User user);

Класс пользователя выглядит следующим образом.

Код: Выделить всё

public class User {
String email;
String password;

public User(String email, String password) {
this.email = email;
this.password = password;
}
}

В основном действии я создаю объект пользователя

Код: Выделить всё

User user = new User("hello_new_user@gmail.com", "123456");

Call call = apiService.registerUser(user);
call.enqueue(new Callback() {
@Override
public void onResponse(Response response, Retrofit retrofit) {
int statusCode = response.code();
System.out.print("Veer " +response.body());
}

@Override
public void onFailure(Throwable t) {
// Log error here since request failed
}
});

Я тоже пробовал,

Код: Выделить всё

Call registerUser(@Body User user);

Но та же ошибка.

ПОЛНЫЙ СЛЕД

Код: Выделить всё
