We have just upgraded our ServiceDesk to the latest build (15120) and now have an issue when selecting the Status, Assigned to, Category from the dropdown list (nothing happens) on the Requests tab or the selection in the top right of the ticket itself.

 

Investigating further, I noticed the below error in the Dev Console relating to the sdp-request.js - Uncaught TypeError: Cannot read properties of undefined (reading 'value')
