Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'

Hello,

I'm trying to write a plugin. I started by testing whether I could display something on the Index page. Here's my code:

        //My main plugin class
        public IList<string> GetWidgetZones()
        {
            return new List<string>{ "home_page_before_news" };
        }

        //My action
        [ChildActionOnly]
        public ActionResult DisplayLink(string widgetZone, object additionalData = null)
        {
            _cacheService.Clear();
            return View("~/Plugins/Widgets.PartnershipManager/Views/DisplayLink.cshtml");
        }

     //My view
     @{ 
        Layout = "";
      }
      
      <a href="#">My first link</a>

I'm getting the following error: Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

With no further information. Yet, I tried to match the code for NivoSlider as much as I can. Am I missing something?

Thanks for helping

Hi,

where are you getting this error: when you are browsing public site or when you are trying to configure your plugin?
what about the GetDisplayWidgetRoute, GetConfigurationRoute methods in your plugin class?

This is where the exception is being thrwon

public static MvcHtmlString Widget(this HtmlHelper helper, string widgetZone, object additionalData = null, string area = null)
        {
            return helper.Action("WidgetsByZone", "Widget", new { widgetZone = widgetZone, additionalData = additionalData, area = area });
        }

And this is the my GetDisplayWidgetRoute method

    public void GetDisplayWidgetRoute(string widgetZone, out string actionName, out string controllerName, out RouteValueDictionary routeValues)
        {
            actionName = "DisplayLink";
            controllerName = "PartnershipManager";
            routeValues = new RouteValueDictionary()
            {
                { "Namespaces", "Nop.Plugin.Widget.PartnershipManager.Controllers" },
                { "area", null },
                { "widgetZone", widgetZone}
            };
        }

Here are both methods

public void GetConfigurationRoute(out string actionName, out string controllerName, out RouteValueDictionary routeValues)
        {
            actionName = "Configure";
            controllerName = "PartnershipManager";
            routeValues = new RouteValueDictionary()
            {
                { "Namespaces", "Nop.Plugin.Widget.PartnershipManager.Controllers" },
                { "area", null }
            };
        }

        public void GetDisplayWidgetRoute(string widgetZone, out string actionName, out string controllerName, out RouteValueDictionary routeValues)
        {
            actionName = "DisplayLink";
            controllerName = "PartnershipManager";
            routeValues = new RouteValueDictionary()
            {
                { "Namespaces", "Nop.Plugin.Widget.PartnershipManager.Controllers" },
                { "area", null },
                { "widgetZone", widgetZone}
            };
        }

hello please help!
