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

can you share the code of OOTB UI action?

also did you try calling the complete endpoint and not just name for the UI page?

If my response helped please mark it correct and close the thread so that it benefits future readers.

@Ankur Bawiskar  Here's screenshot of OOTB UI Action and UI Action script content

UI Action Script -

function openMIMWorkbench() {

    var url = "/$major_incident_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 = "/$major_incident_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;

    }

@linda_richards 

the issue is your UI action is not able to invoke that UI page.

did you try calling the complete name?

I am trying to call the UI page using the complete endpoint URL and the UI page name, but nothing is working.

When examining the OOTB UI action, I see it's calling the UI page as:

var url = "/$major_incident_workbench.do?sysparm_stack=no&sysparm_sys_id=" + g_form.getUniqueValue();
What's confusing is that the OOTB UI page doesn't have any attribute with the value "/$major_incident_workbench". Both the UI page name and endpoint attribute are completely different from what's being referenced. It's unclear where the system is getting the reference to "$major_incident_workbench".

Could you please do me a favor and try to copy the OOTB UI page in your PDI by renaming it, and see if you can call it through View Workbench?
