Where is the listener of "sp.attachments.update"?

Hello everyone,

Inside the Ticket Conversation widget's client script I see a $broadcast for "sp.attachments.update" but I can't seem to find any where that is listening on this event?

Hey @trangdan106,

The sp.attachments.update event is an OOTB broadcast that notifies the platform's internal attachment handler when attachments change—it's not meant to be caught by your custom widget's client script.

The listener is built into ServiceNow's framework-level attachment directives (like sp-attachment components) that manage file display and synchronization . These components automatically refresh when they receive this broadcast.

To trace it, use browser dev tools to search the page's Angular event listeners.

what's your actual business requirement?

The requirements is to change the OOTB behavior of the attachment widgets. I am trying to find where it is broadcasted to hopefully intercept it.
