Getting error while accessing array value in IP17 eScript (ST Engine enabled)

Hi All,

Recently we have upgarded from 8.1.1.9(T engine enabled) to IP17.6(ST engine enabled)Getting below error while accessing the multi-dimensional array-

"TypeError:Can't convert 'Undefined' to Object

PFB the snippet of code-

var ElementName,ElementValue,sTagValue;

var child_Arr_Spec_bi = new Array;

try

{

for (var q=0; q<10; q++)

{

child_Arr_Spec_bi[q][0] = new Object();

child_Arr_Spec_bi[q][1] = new Object();

ElementName = child_Arr_Spec_bi[q][0];

ElementValue = child_Arr_Spec_bi[q][1];

sTagValue = nodTemp.GetProperty(ElementName);

}

}
