hello
how to make custom validators
for unique fields, required
I want to return the same error object which contains the code(400) with message
i use ReactivePanacheMongoRepository as repository

    @BsonId
    private ObjectId id;
    //unique
    private String keyProduct;
    private String logo;
    // not null
    private String status;
    @NotNull
    @Schema(required = true)
    private ProductType type;
}

result Object

public class ResponseError {
    private String code;
    private String message;
    private String field;
}

[
  {
    "code": "4001",
    "field": "status",
    "message": "error"
  }
]

rest ressource

 @POST
    @Path("/add-product")
    @Consumes(MediaType.APPLICATION_JSON)
    @APIResponses(value = {
            @APIResponse(responseCode = "201", content = @Content(mediaType = MediaType.APPLICATION_JSON, schema = @Schema(implementation = ProductDto.class, required = true))),
            @APIResponse(responseCode = "400", content = @Content(mediaType = MediaType.APPLICATION_JSON, schema = @Schema(implementation = ResponseError .class))),
            @APIResponse(responseCode = "401", content = @Content(mediaType = MediaType.APPLICATION_JSON, schema = @Schema(implementation = ResponseError .class))),
         
    })
    @RequestBody(required = true)
    public Uni<Response> addProduct(@Valid ProductDto productDto) {


        return  productService.findKeyIfExist(ProductDto.getProductKey(), null)
                .chain(() -> productService.save(productDto));
    }
