Sorry this is a duplicate in another forum section, but I thought this section more appropriate

I am having a problem with the grid indexer code when deploying to Live.

Basically the indexer fails and none of the pages are available.

    System.Exception: Error indexing queue items,System.MissingMethodException: Method not found: '!!0[] System.Array.Empty()'.
   at NRP.Web.Helper.ExamineIndexer.OnExamineGatheringNodeData(Object sender, IndexingNodeDataEventArgs e)

Works fine locally.

I am using your code with amendments to point to my indexer called"NrpSearchIndexer"

Changing the event to Application "Started" or "Starting" makes no change.

I am I missing something obvious. Feels like it.

Thanks
