here is mycode, in resources,
/// CustomerResource.java ///
`package org.acme.config;

import org.acme.dto.CustomerDto;
import org.acme.service.CustomerService;

import javax.inject.Inject;
import javax.validation.Valid;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
import java.util.List;

@Path("/api/v1/customer")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class CustomerResource {

@Inject
CustomerService customerService;

@OPTIONS
public Response opt() {
    return Response.ok().build();
}

@GET
public List<CustomerDto> list() {
   return customerService.list();

}

@POST
public Response save(@Valid CustomerDto item) {
    //mandatory field (firstName, lastName, phoneNumber)
    if("".equals(item.getFirstName()) && "".equals(item.getLastName()) && "".equals(item.getPhoneNumber())){
        throw new WebApplicationException("There are some data cannot be null", 422);
    }
    customerService.save(item);
    return Response.status(Status.CREATED).entity(item).build();
}

@PATCH
public Response update(@Valid CustomerDto newItem) {
    if (!customerService.exist(newItem.getId())){
        throw new WebApplicationException("Record not foung", 404);
    }
    customerService.update(newItem);
    return Response.ok().entity(newItem).build();
}

@DELETE
@Path("/{id}")
public Response delete(@PathParam("id") String id) {
    if (!customerService.exist(id)){
        throw new WebApplicationException("Record not foung", 404);
    }
    customerService.delete(id);
    return Response.noContent().build();
}

}`

i had try to add ErrorMapper.java class with implements ExceptionMapper
and solved the problem before.
thanks @geoand, hehe

the code like this:
`package org.acme.exception;

import javax.json.Json;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

@Provider
public class ErrorMapper implements ExceptionMapper {

@Override
public Response toResponse(Exception exception) {
    int code = 500;
    if (exception instanceof WebApplicationException) {
        code = ((WebApplicationException) exception).getResponse().getStatus();
    }
    return Response.status(code)
            .entity(Json.createObjectBuilder().add("error", exception.getMessage()).add("code", code).build())
            .build();
}

}
`

@vadly I'm trying to understand, you had a custom error mapper that was not doing the right thing? Or did you have to set an error mapper to do the right thing and fix your problem?

I think this one can be closed. Please reopen if I was wrong.
