Barcode not showing in Manufacture

There is a barcoded item when I am trying to manufacture it and receiving it back at the warehouse the item does not show the barcode in stock entry detail, I am trying to fetch that barcode because I want to print tags, also tried clicking in list view but no benefit
Secondly,
I am trying to fetch barcode value using frappe.db.get_value(“Item”, {“item_code”: row.item_code}, “barcodes”) but it is not working , can you please guide ?
