(GlideRecord) [Q:NOCB] Query must be called with a callback function

[Mr world wide]

I have a catalog client script to make attachment mandatory based on conditions:

function onSubmit() {
	
	//Get the field
	var field= g_form.getValue("hr_process");
	
	//Make attachment mandatory only based on conditions.
	if(field == 'it_infra'){
		
		var cat_id = g_form.getValue('sysparm_item_guid');
		var gr = new GlideRecord("sys_attachment");
		gr.addQuery("table_name", "sn_hr_core_case"); //Update your table
		gr.addQuery("table_sys_id", cat_id);
		gr.query();
		if (!gr.next()) {
			g_form.addErrorMessage('You must add an attachment before submitting this request.');
			return false;
		}
	}
	
	
}

When I click on submit it always throwing the below warning message:
 (GlideRecord) [Q:NOCB] Query must be called with a callback function.
The form is not submitting on the valid case also. How to fix this issue.

Did you accidentally mark other response as correct?

Would you mind marking my response as correct and helpful If I was able to help you?

Greetings Abdul,

 The error relates to your gr.query() line - in that all gliderecord calls from the client side require a responseFunction per - https://developer.servicenow.com/dev.do#!/reference/api/orlando/client/c_GlideRecordClientSideAPI#r_...

But, before you go and adjust that - you should instead, create a script include and use the GlideAjax API, or use the REST APIs

Hi team, I can able to resolve my issue with the following logic:

function onSubmit() {
	
	//Get the field
	var field= g_form.getValue("hr_process");
	
	//Make attachment mandatory only based on conditions.
	if(field == 'it_infra'){
		
		var cat_id = top.window.$("#sc_cat_item").scope().$parent.attachments;
		var length = cat_id.length;
		if(length <= 0) {
			g_form.addErrorMessage('You must add an attachment before submitting this request.');
			return false;
		}
	}
	
	
}
