Issue/Introduction

A couple of users are getting an API-1019 error on MUX timesheets when editing time entries, however they can update the same timesheets through the Classic UI interface.

The app-ca.log file shows the following error:

Developer tools throws a 500 error response on the following PUT:

GROUP BY prresourceid
