workbench_scheduler.js?rrsfvr:64 - Uncaught TypeError: Cannot read properties of undefined (reading 'label')

Problem/Motivation

Found error in the browser console:
workbench_scheduler.js?rrsfvr:64 - Uncaught TypeError: Cannot read properties of undefined (reading 'label')

This causes some conflict to other module with js, It stops other js to load. On the workbench_scheduler.js line 64, if there is no workbench schedule set for the content, variable "type" will be empty and that will throw an error mentioned here.

Anyone have experience this one?
