Telerik Kendo Grid for ASP.Net Core MVC dataSource.read Action Error

Question

I have a simple grid that I am trying to load in my Razor page, but I am getting an error when the page loads. I cannot find a resource that can help with this error.

I did notice that the second line of the error (see full error below) Kendo.Mvc.UI.Fluent.CrudOperationBuilderBase<TCrudOperationBuilder>.Action(string actionName, string controllerName, object routeValues) is indicating that the Action method is expecting an Object to be passed after the controllerName, but all the documentation indicates that only the Action and Controller names are needed. Any insight or help would be greatly appreciated.

Here is my Error

System.NullReferenceException: Object reference not set to an instance of an object.

Here is my Kendo Grid

@(Html.Kendo().Grid<DBManagementUI.Models.ExcludeCCN>()
    .Name("grid")
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("ExcludeCCNs", "ExcludeCCNs"))
    )
    .Columns(columns =>
    {
        columns.Bound(product => product.CCN);
    })
)

Here is my Controller

using Kendo.Mvc.Extensions;
using Kendo.Mvc.UI.Fluent;
using Kendo.Mvc.UI;

namespace Project.Controllers
{
    public class ExcludeCCNsController : Controller
    {
        private readonly CWPAdminContext _context;
        public ExcludeCCNsController(CWPAdminContext context)
        {
            _context = context;
        }

        private IEnumerable<ExcludeCCN> GetExcludeCCNs()
        {
            return _context.ExcludeCCN.Take(100).ToList();
        }

        public IActionResult ExcludeCCNs([DataSourceRequest] 
        DataSourceRequest request)
        {
            return Json(GetExcludeCCNs().ToDataSourceResult(request));
        }

Here is my Startup.cs file

public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddEntityFrameworkSqlServer().AddDbContext<ARCHContext>();
        services.AddEntityFrameworkSqlServer().AddDbContext<CWPAdminContext>();
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
                         .AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
}


    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();
        app.UseKendo(env);
