Update input comes empty #2458

Hi, guys I hope you are well on this Friday :)

I am facing a strange error with a simple update from application service that is called from js.

Let me share some screens and code so that you can review it and maybe you can help me get past through it

this is the js from modal

var _candidateService = abp.services.app.candidate;

        var _modalManager;
     
        var _$candidateLanguageForm = null;

            _$candidateContactInformationForm = _modalManager.getModal().find('form[name=CandidateContactInformation]');


            var candidateLanguage = _$candidateLanguageForm.serializeFormToObject();
 console.log(candidateLanguage);
                    _modalManager.setBusy(true);

                    _candidateService.updateCandidateLanguage({
                        candidateLanguage
                      
                    }).done(function () {
                       
                       abp.notify.info(app.localize('SavedSuccessfully'));
                       //_modalManager.close();
                       //abp.event.trigger('app.createOrEditCandidatesModalSaved');
                   }).always(function () {
                       _modalManager.setBusy(false);
                   });

This is the app service method input

[AbpAuthorize(AppPermissions.Pages_Administration_Candidates_Edit)]
        public async Task UpdateCandidateLanguage(UpdateCandidateLanguageInput input)
        {
            //Debug.Assert(input.CandidateId == null, "input.Candidate.Id should be set.");

            var candidate = await _candidateRepository.GetAsync(input.Id);
            if (candidate == null)
            {
                throw new UserFriendlyException("Candidate does not exist!");
            }

            candidate.CorrespondanceLanguage = input.CorrespondanceLanguage;
            candidate.NativeLanguage = input.NativeLanguage;

            await _candidateRepository.UpdateAsync(candidate);
        }

dto

public class UpdateCandidateLanguageInput
    {
        public long Id { get; set; }
        public string NativeLanguage { get; set; }
        public CandiadteCorrespondanceLanguage? CorrespondanceLanguage { get; set; }
    }

viewmodel

public class CandidateLanguageViewModel : UpdateCandidateLanguageInput
    {

        public IReadOnlyList<ComboboxItemDto> SpokenLanguages { get; set; }

        public CandidateLanguageViewModel(long candidateId, CandiadteCorrespondanceLanguage? language, string nativelanguage, IReadOnlyList<ComboboxItemDto> spokenLanguages)
        {
            Id = candidateId;
            CorrespondanceLanguage = language;
            NativeLanguage = nativelanguage;
            // output.MapTo(this);
            SpokenLanguages = spokenLanguages;
        }
    }

filling of the viewmodel on controller

[AbpMvcAuthorize(AppPermissions.Pages_Administration_Candidates_Create, AppPermissions.Pages_Administration_Candidates_Edit)]
        public async Task<PartialViewResult> CreateOrEditModal(int? id)
        {
            var output = await _candidateAppService.GetCandidateForEdit(new NullableIdDto<long> { Id = id });

            var viewModel = new CreateOrEditCandidateModalViewModel(output);


            //get two list item types with one db call
            var nationalitiesAndSpokenLanguages = _listAppService.GetListItemsByType
                (new GetListItemInput()
                {
                    ListType = new[] { RecruitingConsts.ListTypes.Country, RecruitingConsts.ListTypes.SpokenLanguage }
                });

            
            viewModel.ManagersAndTeamLeaders =
                await
                    _candidateAppService.FindUsersInRole(new FindUsersInput()
                    { Roles = new[] { StaticRoleNames.Tenants.Manager, StaticRoleNames.Tenants.TeamLeader } });

            //split two list items in memory
            viewModel.Nationalities = nationalitiesAndSpokenLanguages.Items.Where(dto => dto.ListType == RecruitingConsts.ListTypes.Country)
                .Take(10).OrderBy(o=> o.Text)
                .Select(e => new ComboboxItemDto(e.Id.ToString(), e.Text)).ToList();

            var spokenLanguages = nationalitiesAndSpokenLanguages.Items.Where(dto => dto.ListType == RecruitingConsts.ListTypes.SpokenLanguage)
                .Take(10).OrderBy(o => o.Text)
                .Select(e => new ComboboxItemDto(e.Id.ToString(), e.Text)).ToList();


            if (id.HasValue)
            {
                var candidateLanguage = new UpdateCandidateLanguageInput();
                candidateLanguage.Id = viewModel.Candidate.Id.Value;
                candidateLanguage.NativeLanguage = viewModel.Candidate.NativeLanguage;
                candidateLanguage.CorrespondanceLanguage = viewModel.Candidate.CorrespondanceLanguage;

                // viewModel.Candidate.MapTo<UpdateCandidateLanguageInput>();
                
                viewModel.AddressViewModel = new CandidatesAddressViewModel(viewModel.CandidateAddress, viewModel.Nationalities);
                viewModel.ContactInformationViewModel = new CandidateContactInformationViewModel(viewModel.CandidateContactInformation);
                viewModel.LanguagesViewModel = new CandidateLanguageViewModel(viewModel.Candidate.Id.Value, viewModel.Candidate.CorrespondanceLanguage, 
                    viewModel.Candidate.NativeLanguage, spokenLanguages);

            }



            return PartialView("_CreateOrEditModal", viewModel);
        }
