I think it should be

	sales_invoice_doc.append('items', {
		"item_code": sales_invoice_doc.item_code,
        "qty": sales_invoice_doc.qty,
        "rate": sales_invoice_doc.rate,
        "amount": sales_invoice_doc.amount,
        "uom": default_uom,		
		"conversion_factor": 1.0,
		"item_name": sales_invoice_doc.item_name,
		"description": sales_invoice_doc.item_name,
		"income_expense_account_field": sales_invoice_doc.temporary_opening_account,
		"cost_center": sales_invoice_doc.cost_center
    })

This one use take fields in sales invoice:-
sales_invoice_doc = frappe.new_doc(“Sales Invoice”)
sales_invoice_doc.customer= customer
sales_invoice_doc.due_date = due_date

This one take fields in Items table which is a child table in sales invoice
sales_invoice_doc = frappe.db.get_value(‘items’.append({
“item_code”: sales_invoice_doc.item_code,
“qty”: sales_invoice_doc.qty,
“rate”: sales_invoice_doc.rate,
“amount”: sales_invoice_doc.amount,
“uom”: default_uom,

		"conversion_factor": 1.0,
		"item_name": sales_invoice_doc.item_name,
		"description": sales_invoice_doc.item_name,
		"income_expense_account_field": sales_invoice_doc.temporary_opening_account,
		"cost_center": sales_invoice_doc.cost_center

		}))
