When sending a Post request using Swagger-UI, I get an empty object - spring-mvc

Question

I am sending a Post request from the page http://localhost:9003/swagger-ui.html
Here I get this request sent using Swagger-UI
#Slf4j
#RestController
#RequestMapping("/api/book")
public class BookController {
#PostMapping("/create")
#ResponseStatus(HttpStatus.CREATED)
public Book postBook(#NotNull #Valid #RequestBody final Book book) {
log.info("Book request data {}", book );
return "Create book";
}
}
As a result of executing the postBook method, I get an empty object
Book request data(id=0, title=null, author=null)
Class Book
#Getter
#Setter
#ToString
#EqualsAndHashCode
public class Book {
private long id;
#NotBlank
#Size(min = 0, max = 20)
private String title;
#NotBlank
#Size(min = 0, max = 30)
private String author;
}

I don't understand what the problem might be. Error when converting from json format.
The jackson dependency is connected to my project. What else is missing?
Here's what the browser console shows (F12 -> network -> request -> payload)
{id: 0, title: "string", author: "string"}
author: "string"
id: 0
title: "string"
