Server Error in '/' Application.

We narrowed the issue down to this line:

ExamineManager.Instance.IndexProviderCollection[Indexer].GatheringNodeData += ExamineEvents_GatheringNodeData;

Hi Derrik

Have you tried clearing the client dependency cache?

1: Go to /app_data/TEMP/ClientDependency and delte the files in the folder 2: Go to /config/ClientDependency.config and increment the version attribute 3: Recycle the app pool

In the /app_data/TEMP folder it might also be a good idea to delete the temp files in the Examine folder as well.

Does that help?

Hi Derrik,

I had the exact same issue. Are you using the GatheringNodeData event in an ApplicationEvent by any chance? Like the following?

using Examine;
using Umbraco.Core;

namespace Application.Events
{
    public class CustomApplicationEvent : ApplicationEventHandler
    {
        public CustomApplicationEvent()
        {
            ExamineManager.Instance.IndexProviderCollection["CustomIndexer"].GatheringNodeData
                += OnGatheringNodeData;
        }

        private static void OnGatheringNodeData(object sender, IndexingNodeDataEventArgs e)
        {
        }
    }
}

If you are, like me, then you are doing it wrong. See this documentation page for more information. You'll want to go through all your application events and make sure you are implementing them in the correct way. Like the following:

using Examine;
using Umbraco.Core;

namespace Application.Events
{
    public class CustomApplicationEvent : IApplicationEventHandler
    {
        private static readonly object s_LockObj = new object();
        private static bool s_Ran; 

        public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            if (s_Ran) 
                return;

            lock (s_LockObj)
            {
                if (s_Ran) 
                    return;

                ExamineManager.Instance.IndexProviderCollection["CustomIndexer"].GatheringNodeData
                    += OnGatheringNodeData;

                s_Ran = true;
            }
        }

        private static void OnGatheringNodeData(object sender, IndexingNodeDataEventArgs e)
        {
        }

        public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
        }

        public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
        }
    }
}

Hope that helps.

Thanks, Dan.
