I got this error in all grid features, mainly the one appears first in list. If I comment that out then it shows on next one. Can you please create an sample at your side to see an error, using datasource from my previous post and below is my java script file. Error appears on row expanding.

function getMaterialPricesList() {
    try{
    $.ig.loader(function () {
