Hi May,

Can you show us the code of the controller ?

Dave

I just had this same issue myself, I narrowed it down to some kind of weird routing issue and if I set the forms action to a valid view url it then posted to the surface controller quite happily

So for example I did this

@using (Html.BeginUmbracoForm<MembershipSurfaceController>("SubmitSigninForm", null, new { id = "submitsigninform", action = "/login"}, FormMethod.Post))
{
    .....
}

Where "/login" is the actual view that hosts the viewcomponent

Hello everyone, I am having this same problem. What can I do please? This is the LoginController code:

using Microsoft.AspNetCore.Mvc; using Microsoft.Extensions.DependencyInjection; using Umbraco.Cms.Core.Cache; using Umbraco.Cms.Core.DependencyInjection; using Umbraco.Cms.Core.Logging; using Umbraco.Cms.Core.Routing; using Umbraco.Cms.Core.Security; using Umbraco.Cms.Core.Services; using Umbraco.Cms.Core.Web; using Umbraco.Cms.Infrastructure.Persistence; using Umbraco.Cms.Web.Common.ActionsResults; using Umbraco.Cms.Web.Common.Filters; using Umbraco.Cms.Web.Common.Models; using Umbraco.Cms.Web.Common.Security; using Umbraco.Cms.Web.Website.Controllers; using Umbraco.Extensions; using SignInResult = Microsoft.AspNetCore.Identity.SignInResult;

namespace AmanaCard.Controllers { public class LoginController : SurfaceController {

    private readonly IMemberManager _memberManager;
    private readonly IMemberSignInManager _signInManager;
    private readonly ITwoFactorLoginService _twoFactorLoginService;

    [ActivatorUtilitiesConstructor]
    public LoginController(
        IUmbracoContextAccessor umbracoContextAccessor,
        IUmbracoDatabaseFactory databaseFactory,
        ServiceContext services,
        AppCaches appCaches,
        IProfilingLogger profilingLogger,
        IPublishedUrlProvider publishedUrlProvider,
        IMemberSignInManager signInManager,
        IMemberManager memberManager,
        ITwoFactorLoginService twoFactorLoginService)
        : base(umbracoContextAccessor, databaseFactory, services, appCaches, profilingLogger, publishedUrlProvider)
    {
        _signInManager = signInManager;
        _memberManager = memberManager;
        _twoFactorLoginService = twoFactorLoginService;
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    [ValidateUmbracoFormRouteString]
    public async Task<IActionResult> HandleLogin([Bind(Prefix = "loginModel")] LoginModel model)
    {
        if (ModelState.IsValid == false)
        {
            return CurrentUmbracoPage();
        }

        MergeRouteValuesToModel(model);

        // Sign the user in with username/password, this also gives a chance for developers to
        // custom verify the credentials and auto-link user accounts with a custom IBackOfficePasswordChecker
        SignInResult result = await _signInManager.PasswordSignInAsync(
            model.Username, model.Password, model.RememberMe, true);

        if (result.Succeeded)
        {
            TempData["LoginSuccess"] = true;

            // If there is a specified path to redirect to then use it.
            if (model.RedirectUrl.IsNullOrWhiteSpace() == false)
            {
                // Validate the redirect URL.
                // If it's not a local URL we'll redirect to the root of the current site.
                return Redirect(Url.IsLocalUrl(model.RedirectUrl)
                    ? model.RedirectUrl
                    : CurrentPage!.AncestorOrSelf(1)!.Url(PublishedUrlProvider));
            }

            // Redirect to current URL by default.
            // This is different from the current 'page' because when using Public Access the current page
            // will be the login page, but the URL will be on the requested page so that's where we need
            // to redirect too.
            return RedirectToCurrentUmbracoUrl();
        }

        return CurrentUmbracoPage();

    }

    private void MergeRouteValuesToModel(LoginModel model)
    {
        if (RouteData.Values.TryGetValue(nameof(LoginModel.RedirectUrl), out var redirectUrl) && redirectUrl != null)
        {
            model.RedirectUrl = redirectUrl.ToString();
        }
    }
}

}

I always got the same error if creating the project from VS umbraco 10 project.

Please try re-creating your project using the command below, and then add your controllers, etc. back.

dotnet new sln --name "MySolution" dotnet new umbraco --force -n "MyProject" --friendly-name "Administrator" --email "admin@example.com" --password "1234567890" --development-database-type SQLite

dotnet sln add "MyProject"

is working on a reply...
