OBJ.length returning null for Multi row variable set

[Community Alums]

Hi folks,

I want to retreive manager sys ID from MRV set,

MRV set is returning list of records as OBJ, when i try ulist.length it's throwing null.

Is there any other way to retreive values from MRV set ?

var gr= new GlideRecord('sc_req_item');
gr.addQuery('sys_id','a21b171297a5021051673e2e6253af8f');
gr.query();
var i;
if(gr.next()){
	gs.info('hello');
	var val= gr.variables.select_the_group;

	var ulist= gr.variables.select_users;//retreiving values from MRV.


gs.info(val);
	
gs.info(ulist);
gs.info(ulist.length);
}

Output:

Hi @Community Alums,

You can either use a Flow to iterate through the values of an MRVS or use the following script:

var mrvs = current.variables.your_mrvs_name;
var rowCount = mrvs.getRowCount();
//loop through the MRVS contents
for (var i = 0; i < rowCount; i++) {
    var row = mrvs.getRow(i);
    gs.info(row.variable_name_mrvs);
}
