Issue/Introduction

Unable to export or download most of the policies in the Enforce console.
A few of the policies can be successfully exported or downloaded.

When the export fails, they receive a red banner saying:
Either:
"Download failed because one or more policies were deleted."
Or:
"An unexpected error has occurred. This could be due to one of the following: 1) Your session timed out and you selected a link that was no longer valid, 2) You used the browser back and forward button placing the system into an inconsistent state, or 3) The system experienced a temporary problem."

The policies do exist and work, they do generate incidents.

The localhost log has these types of entries:

Level: SEVERE
