Error in ContentEventIndexer


After upgrading to EPiServer v 10.+ and Epi Find to, the following error is found in the log, multiple times per minute:

2017-03-06 16:30:27,779 [129] ERROR EPiServer.Find.Cms.ContentEventIndexer: An exception occurred while indexing (IContent). Error getting value from 'AttributesString' on 'Castle.Proxies.TextareaElementBlockProxy'..

The website and Epi Find search although is working as expecting. What could be the cause of this error?

we've just got the same error on Episerver logs. It seems that these items are not indexed properly and are stuck in the indexing queue...

We solved it by telling EPiServer Find to exclude the Forms elements, something like:

ContentIndexer.Instance.Conventions.ForInstancesOf<IContent>().IndexingInContentAreas(x =>
   if (x is IElementBlock)
      return false;
   return true;

ContentIndexer.Instance.Conventions.ForInstancesOf<IContent>().ShouldIndex(x => !(x is IElementBlock));

As it was trying to index the form elements from the Media Content folder as well for items in shared,
