I am facing the following error:
ERROR Cannot create tracker. Exception: System.IndexOutOfRangeException Message: Index was outside the bounds of the array. Source: mscorlib at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at Sitecore.Analytics.Model.Framework.ModelFactory.GetConcreteType(Type elementType) at Sitecore.Analytics.Model.Framework.ModelFactory.CreateElement(Type elementType) at Sitecore.Analytics.Model.Framework.ModelFactory.CreateFacet(Type facetType) at Sitecore.Analytics.Model.Framework.Faceted.AddFacet(String name, Type type) at Sitecore.Analytics.Model.Framework.ModelFactory.CreateContact(ID id, IReadOnlyDictionary`2 facets) at Sitecore.Analytics.Data.ContactFactory.Create(ID id) at Sitecore.Analytics.Data.ContactRepository.CreateContact(ID id) at Sitecore.Analytics.Pipelines.EnsureSessionContext.LoadContact.Process(InitializeTrackerArgs args) at (Object , Object[] ) at Sitecore.Pipelines.CorePipeline.Run(PipelineArgs args) at Sitecore.Analytics.Pipelines.EnsureSessionContext.EnsureSessionContextPipeline.Run(InitializeTrackerArgs args) at Sitecore.Analytics.DefaultTracker.EnsureSessionContext() at Sitecore.Analytics.Pipelines.CreateTracker.GetTracker.Process(CreateTrackerArgs args) at (Object , Object[] ) at Sitecore.Pipelines.CorePipeline.Run(PipelineArgs args) at Sitecore.Analytics.Tracker.Initialize()
Per this post I verified that we have those config values present in our solution.
Still, randomly I get this error on one of the CD servers and not on all. Any idea why?
