I saw this error while working on an On-Premise installation of Dynamics CRM 2013 when trying to run or edit a custom report. I tried isolating the issue to my report, but it was still showing on system (out-of-the-box) reports. While there are other reporting errors that show, this could be the root cause of the problem. Fixing this can either eliminate future errors or hint at a deeper issue on a server. Let’s take a look at the full error and troubleshoot from there.
