Our UI Action calls a global client function that should invoke GlideAjax sysparm_name=getAjaxResponse on APMScoresFetcher, but browser network traces show requests going to AJAXXMLHttpAggregator / MultiSourceAjax (sysparm_name=isEnabled) instead. Root cause: duplicate/old UI Script was being executed by the browser; disabling extra UI Scripts and hard‑refreshing the same tab forced the correct client script and fixed the issue.
