how to populate assigned to field in catalog task who approves that RITM

[Deepika43]

In my requirement, flow designer were created for the catalog item. Now,  the Assigned to field is populated with the name of the person that provided the approval. 
I tried with the script for assigned to field. But, not working as expected.

var app = new GlideRecord('sysapproval_approver');

app.addQuery('sysapproval',current.sys_id);

app.addQuery('state',"approved");

app.query();

if (app.next()){

task.assigned_to = app.approver;

}

tried this too

this is catalog task creation so here I added assigned to field with script expanded.

do this

var sysId = fd_data.trigger.current.sys_id;

// pick the latest approver
var gr = new GlideRecord("sysapproval_approver");
gr.orderByDesc("sys_updated_on");
gr.addQuery("state","approved");
gr.addQuery("sysapproval", sysId);
gr.setLimit(1);
gr.query();
return gr.approver;
