new model CRUD issue, does not create and update.

[kirkey]

I have a problem with creating new CRUD module while the stock modules (Brand and Products) are totally fine for creating and updating. Please check these series of code why it doesn't work and keeps on displaying error "One or more validation errors occurred.",
"status": 400,"

Domain:
`public class Group : AuditableEntity, IAggregateRoot
{
public string Application { get; private set; } = default!;
public string Parent { get; private set; } = default!;
public string Code { get; private set; } = default!;
public string Name { get; private set; } = default!;
public string? Manager { get; private set; }
public string? Description { get; private set; }
public string? Notes { get; private set; }
public string? ImagePath { get; private set; }

public Group(string application, string parent, string code, string name, string? manager, string? description, string? notes, string? imagePath)
{
    Application = application;
    Parent = parent;
    Code = code;
    Name = name;
    Manager = manager;
    Description = description;
    Notes = notes;
    ImagePath = imagePath;
}

public Group Update(string application, string parent, string code, string name, string? manager, string? description, string? notes, string? imagePath)
{
    if (application is not null && Application?.Equals(application) is not true) Application = application;
    if (parent is not null && Parent?.Equals(parent) is not true) Parent = parent;
    if (code is not null && Code?.Equals(code) is not true) Code = code;
    if (name is not null && Name?.Equals(name) is not true) Name = name;
    if (manager is not null && Manager?.Equals(manager) is not true) Manager = manager;
    if (description is not null && Description?.Equals(description) is not true) Description = description;
    if (notes is not null && Notes?.Equals(notes) is not true) Notes = notes;
    if (imagePath is not null && ImagePath?.Equals(imagePath) is not true) ImagePath = imagePath;
    return this;
}

public Group ClearImagePath()
{
    ImagePath = string.Empty;
    return this;
}

}`

Application:
`public class CreateGroupRequest : IRequest
{
public string Application { get; private set; } = default!;
public string Parent { get; private set; } = default!;
public string Code { get; private set; } = default!;
public string Name { get; private set; } = default!;
public string? Manager { get; private set; }
public string? Description { get; private set; }
public string? Notes { get; private set; }
public FileUploadRequest? Image { get; set; }
}

public class CreateGroupRequestHandler : IRequestHandler<CreateGroupRequest, Guid>
{
private readonly IRepository _repository;
private readonly IFileStorageService _file;

public CreateGroupRequestHandler(IRepository<Group> repository, IFileStorageService file) =>
    (_repository, _file) = (repository, file);

public async Task<Guid> Handle(CreateGroupRequest request, CancellationToken cancellationToken)
{
    string imagePath = await _file.UploadAsync<Product>(request.Image, FileType.Image, cancellationToken);

    var group = new Group(request.Application, request.Parent, request.Code, request.Name, request.Manager, request.Description, request.Notes, imagePath);

    // Add Domain Events to be raised after the commit
    group.DomainEvents.Add(EntityCreatedEvent.WithEntity(group));

    await _repository.AddAsync(group, cancellationToken);

    return group.Id;
}

}

public class CreateGroupRequestValidator : CustomValidator
{
public CreateGroupRequestValidator(IReadRepository group, IStringLocalizer localizer)
{
RuleFor(p => p.Application)
.NotEmpty()
.MaximumLength(16);

    RuleFor(p => p.Parent)
        .NotEmpty()
        .MaximumLength(16);

    RuleFor(p => p.Code)
        .NotEmpty()
        .MaximumLength(16)
        .MustAsync(async (code, ct) => await group.GetBySpecAsync(new GroupByCodeSpec(code), ct) is null)
            .WithMessage((_, code) => string.Format(localizer["group.alreadyexists"], code));

    RuleFor(p => p.Name)
        .NotEmpty()
        .MaximumLength(1024)
        .MustAsync(async (name, ct) => await group.GetBySpecAsync(new GroupByNameSpec(name), ct) is null)
            .WithMessage((_, name) => string.Format(localizer["group.alreadyexists"], name));

    RuleFor(p => p.Image)
        .SetNonNullableValidator(new FileUploadRequestValidator());
}

}`

Controller:
[HttpPost] [MustHavePermission(FSHAction.Create, FSHResource.Groups)] [OpenApiOperation("Create a new Group.", "")] public Task<Guid> CreateAsync(CreateGroupRequest request) { return Mediator.Send(request); }

You're not showing the most important part: the actual request you did and the response you received.

If you get "one or more validation errors occurred" then those errors should also be part of the response...

(also: you can use the "Add code" button here on github to format your code... You can even annotate it (the opening 3 backticks) with "c#" to make it colorful ;-))

Hi, surprisingly the response is too soon but I have been stuck in here since monday. I am testing it first through swagger and the response is:
{ "type": "https://tools.ietf.org/html/rfc7231#section-6.5.1", "title": "One or more validation errors occurred.", "status": 400, "traceId": "00-5ad27aa631763f6fa57c6c6fc7cad61c-5872f0d1f25eb642-00", "errors": { "Code": [ "The Code field is required.", "'Code' must not be empty." ], "Name": [ "The Name field is required.", "'Name' must not be empty." ], "Parent": [ "The Parent field is required.", "'Parent' must not be empty." ], "Application": [ "The Application field is required.", "'Application' must not be empty." ] } }

And the request? Seems like you're not sending anything for code, name, parent and application...
