asp.net boilerplate: value cannot be null. Paramater name: key

Question

I'm trying to create a record in db but I take this error at below.

This is the error

 ArgumentNullException: Value cannot be null.
 Parameter name: key
System.Collections.Generic.Dictionary<TKey, TValue>.FindEntry(TKey key)
Microsoft.AspNetCore.Http.Internal.RequestCookieCollection.ContainsKey(string key)
Abp.AspNetCore.Mvc.Antiforgery.AbpAutoValidateAntiforgeryTokenAuthorizationFilter.ShouldValidate(AuthorizationFilterContext context) in AbpAutoValidateAntiforgeryTokenAuthorizationFilter.cs
Microsoft.AspNetCore.Mvc.ViewFeatures.Internal.ValidateAntiforgeryTokenAuthorizationFilter.OnAuthorizationAsync(AuthorizationFilterContext context)
Microsoft.AspNetCore.Mvc.Internal.ResourceInvoker.InvokeFilterPipelineAsync()

Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore.DatabaseErrorPageMiddleware.Invoke(HttpContext httpContext)
Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore.DatabaseErrorPageMiddleware.Invoke(HttpContext httpContext)
Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context)

This is my controller:

  public IActionResult Index()
    {
        return View();
    }
    [HttpPost]
    public  IActionResult Index(CreateUserInput input)
    {
        if (HttpContext.Request.Cookies.ContainsKey(".AspNetCore.Antiforgery."))
        {
            _userAppService.Create(input);
        }

        return RedirectToAction("Index","Home");
    }

this is my html page:

  @model DutyV2.Users.DTO.CreateUserInput
@{
    ViewData["Title"] = "Index";
}

<h2>Index</h2>
<form asp-action="Index" method="post">
    <div class="input-group">
        <label class="control-label" asp-for="Name"></label>
        <input asp-for="Name" class="form-control" type="text" />
    </div>
    <div class="input-group">
        <label class="control-label" asp-for="Email"></label>
        <input asp-for="Email" class="form-control" type="email" />
    </div>
    <input type="submit" value="Create"/>
</form>

Update your ABP version to v4.0.1 or above.

It is due to ContainsKey getting called with null if cookie authentication is not used.

The bug occurred in AbpAutoValidateAntiforgeryTokenAuthorizationFilter and AbpValidateAntiforgeryTokenAuthorizationFilter.
