Issue
Warning : Undefined array key “playlistId” in /var/www/cms/lib/Factory/LayoutFactory.php on line 640
specifically when trying to edit a schedule event for a layout, the warning is displayed and the menu is scrambled. First experienced on CMS Version 4.1.0. I set up a test environment of CMS Version 4.2.0 (docker on debian 12 VM) and didnt experience the issue. After updating our production to V4.2.0 following this guide, the issue persists. Thats why i am unsure if it is a bug. Duplicate of this Thread: https://community.xibo.org.uk/t/incorrect-display-of-the-schedule/30788
Any help is greatly appreciated!
