hiii

I am new to aras innovator . i written following code but method in inn.applyMethod() is js and it gives error that it is not currently supported

Innovator inn = this.getInnovator();
{
string sFormulaId = this.getProperty("id");
Item iDisp = inn.newItem("Symbi_Dispensing BMR","get");
iDisp.setProperty("id",sFormulaId);
Item result = iDisp.apply();
//return inn.newError(result.ToString());

/////////////////////////////GET DISPENSING TAB ITEM//////////////
Item iDispItem = this.newItem("Symbi_Dispensing_Item","get");
iDispItem.setProperty("source_id",iDisp.getProperty("id"));
iDispItem.getAttribute("select","related_id");
Item resDispItem = iDispItem.apply();
int countDispItem = resDispItem.getItemCount();
for(int i=0; i<countDispItem; i++)
{
    Item DispItemRel = resDispItem.getItemByIndex(i);
    Item rItem = DispItemRel.getRelatedItem();
//return inn.newError(DispItemRel.getProperty("symbi_net_uom"));

    /////////////////////////////GET THE ADDED ITEM ////////////////////
Item rFMItem = this.newItem(rItem.getType());
rFMItem.setID(rItem.getID());
Item resFMItem = rFMItem.apply("get");
    //return inn.newError(resFMItem.getProperty("symbi_qtybal_uom"));
string FMItemUOM = resFMItem.getProperty("symbi_qtybal_uom");
string FMItemid = resFMItem.getProperty("id");
string dispQtyUOM = DispItemRel.getProperty("symbi_net_uom");
//return inn.newError(DispItemRel.getProperty("symbi_net_uom"));
    if(dispQtyUOM==FMItemUOM)
        {
   
string sQtyBal = resFMItem.getProperty("symbi_qty_balance");
string sNetwt =  DispItemRel.getProperty("symbi_net_wt");
if(int.Parse(sNetwt) ==0)
{
    return inn.newError("Quantity is Zero");
}


    if(int.Parse(sNetwt) <= int.Parse(sQtyBal))
    {
   
////////////////////ADD BIN CARD BASED ON NUMBER OF ITEM PRESENT IN  DISPENSING ITEM TAB////////////////
Item iBinCard = this.newItem("Symbi_Bin Card");
iBinCard.setProperty("symbi_ar_no",DispItemRel.getProperty("symbi_ar_no"));
