Error while calling custom UI Page in Major Incident Management

[linda_richards]

Hello Community,

My requirement is to customize the Major Incident Management UI page that appears after clicking the 'View Workbench' UI action within a major incident record. I am attempting to call my custom UI page by overriding the Out-of-the-Box 'View Workbench' UI action, but I am encountering the following error. 

Your help is much appreciated.

Thanks,

Linda

Removing $ sign from below syntax has fixed the issue. $ symbol is reserved for OOTB system UI pages, hence it should not be used for custom UI pages. var url = "/$<ui_page_endpoint>.do?sysparm_stack=no&sysparm_sys_id=" + g_form.getUniqueValue();

Thanks,

Linda
