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

As I've mentioned in the original post that I've overriden the OOTB UI Action.I can see my UI action have successfully overriden the OOTB version as I can see custom validation message is getting displayed on the screen. Both UI action and UI page are under application scope of Major incident management. In OOTB UI action I am just giving reference to my custom UI Page like this 

function openMIMWorkbench() {

    alert('Success');

    var url = "/$custom_workbench.do?sysparm_stack=no&sysparm_sys_id=" + g_form.getUniqueValue();

    var isPolarisEnabled = isPolaris();

    if (isPolarisEnabled) {

        var polarisPrefixUrl = "/now/nav/ui/classic/params/target/";

        var query = "/$custom_workbench.do?sysparm_stack=no&sysparm_full_theme_support=true&sysparm_use_polaris=true&sysparm_sys_id=" + g_form.getUniqueValue();

        query = encodeURIComponent(query);

        url = polarisPrefixUrl + query;

    }

    var gsftFrame = parent.document.getElementById('gsft_main');

    //https://buildtools1.service-now.com/kb_view_customer.do?sysparm_article=KB0536462

    if(!gsftFrame)

            gsftFrame = parent.document.getElementById('testFrame');

    if (gsftFrame) {

        var gsftWindow = gsftFrame.contentWindow || gsftFrame.contentDocument;

        gsftWindow.location = url;

    }

    else {

        parent.location = url;

    }

}
