Not able to query SharePoint from Nintex form custom JavaScript

Question

I'm trying to query the SharePoint list using JSOM from Nintex custom javascript. My intention is to show the data in Nintex multiLine textbox. I can query data from SharePoint and display it in the Nintex edit form and not able to query from the Nintex view/display form.

Any thoughts? Thanks!.

Please refer the below code

 var clientContext;
    var oListItem;
    var workFlowListName = "sharepoint Tasks";
    var requestId = 1;
    var pollSP;

   function checkSPLoad() {
   if (clientContext) {
   window.clearInterval(pollSP);
   if (requestId)
   GetPFItems();
   }

  }

  function GetPFItems() {
   var oList = clientContext.get_web().get_lists().getByTitle(workFlowListName);
   var camlQuery = new SP.CamlQuery();
   camlQuery.set_viewXml("<View><Query><Where><Eq><FieldRef Name='ID' /><Value Type='Text'>" + requestId 
   + "</Value></Eq></Where></Query></View>");
   this.collListItem = oList.getItems(camlQuery);
   clientContext.load(collListItem);
   clientContext.executeQueryAsync(Function.createDelegate(this, this.PFQuerySucceeded), 
   Function.createDelegate(this, this.onQueryFailed));
   }

   function PFQuerySucceeded(sender, args) {
   var listItemEnumerator = collListItem.getEnumerator();
   while (listItemEnumerator.moveNext()) {
   var oListItem = listItemEnumerator.get_current();
   pfTaskName = oListItem.get_item('TaskName');

   NWF$('#'+'sampleTextBox').val(pfTaskName);
   }
   }

   function onQueryFailed(sender, args) { }

Why your CAML Query has data type as Text for ID field? Also, You need to configure multiline textbox's setting and make display mode as Edit. This should start getting populated.
