Uncaught TypeError: Cannot read property 'style' of null

I'm looking at an RITM.

On this RITM, I have a Macro variable (pointing to a SP Widget) that seems to be causing this issue.  If I make this macro variable active = false, this RITM loads fine.

Since the error is on ServiceNow's code side, I suppose there's no fix for this... however, it leaves one to beg the question, why do the individuals that code ServiceNow itself never do any try/catch or "if element exists" code???

Bad coding practice (ServiceNow default):

ge.getElementParentNode().style.display = "none"

Good coding practice:

if (ge.getElementParentNode())
     ge.getElementParentNode().style.display = "none"

The problem is, because of this error, the entire page breaks and any UI Policy, Client Script, ... anything that uses JavaScript fails.

I faced the same issue, this happens when ever you are trying to show/hide the variable which is Macro.
something like g_form.setDisplay('macro_name',false);

as Alternative I am using the DOM manipulation by adding the DIV ID on the macro and using below

var x = document.getElementById('DIV ID');
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}

Wish that were true.

I'm getting this now on a checkbox variable.  If I make this "Active = false", I no longer have the issue.

Found the same issue with Kingston and was given this workaround and it worked for us

The workaround can also be found using the following URL:
KB0691852 - Request Item and Service catalog task forms are broken after upgrading Kingston Patch 6

Yep, that workaround solved it for us as well.  Thanks!
