Model class is not reflecting example and description in Swagger UI

Question

I have spring boot application where we are using swagger for documentation using spring-fox. Issue is , in the swagger UI , model class is not showing the example and description , not sure what is missing .

after googling, it seems issue with some version mismatch or the media type which is being produced. Not sure though

I followed the solution mentioned here as well , but not getting what is missing ...

The model class

public class Product implements Serializable {

    @Schema(name = "Product ID", example = "1", required = true)
    private Long id;
    @Schema(name = "Product name", example = "Product 1", required = false)
    private String name;
    @Schema(name = "Product price", example = "$100.00", required = true)
    private String price;

    // constructor and getter/setters

    public Product(long id, String name, String price) {
        this.id = id;
        this.name = name;
        this.price = price;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }

    public String getPrice() {
        return price;
    }

    public void setPrice(String price) {
        this.price = price;
    }
}

Controller class

@RestController
@Tag(name = "Cloud Controller API")
public class CloudController {

  @Operation(summary = "Get a product by id", description = "Returns a product as per the id")
        @ApiResponses(value = {
                @ApiResponse(code = 200, message = "Successfully retrieved"), @ApiResponse(code = 404, message = "Not found - The product was not found")
        })
        @GetMapping(value = "/products/{id}", produces = MediaType.APPLICATION_JSON_VALUE)
      public ResponseEntity<Product> getProduct(@PathVariable("id") @Schema(name = "id", description = "Product id", example = "1") Long id) {
            //retrieval logic
            return ResponseEntity.ok(new Product(1, "Product 1", "$21.99"));
        }
