Exceptions

Hello and thank you for your reply in advance.

We are currently running your Aricie Lucene search on our website. We also have the DotNetNuke Documents module on our site. This is the free one from codeplex.
When we add this module to be indexed - we noticed in our log files that allot of exception are being thrown.

If we uncheck the option to index this module all the errors go away.
I was wondering if anyone else have these problems?
Also if anyone knows if the issue is with the document module or the search module.
We are running version 1.8.3 Lucene search and DNN version 7.2.1.
