Unable to create Notification

[samadam]

I am trying to create a notification and getting this error:

onSubmit script error: TypeError: Cannot read properties of undefined (reading 'options'):

function() {
      var hinput = $(ref);
      var cfilter = getFilter(ref);
      hinput.value = unescape(cfilter);
      CustomEvent.fire("sys_mapping:on_cond_submit::" + ref, { value: hinput.value, ref: ref });
     }

It suddenly started any ideas on how to resolve?

I tried chrome in incognito mode, cleared cache and tried edge as well. Nothing helped.

If you can identify where ref is coming from and ensure it's properly initialized, this should resolve the issue.
