I'm tring to get price of product based on price list selected , but the error occur , it said not exist :

'price_list':sale.pricelist_id.get_product_price(line.product_id)
AttributeError: 'product.pricelist' object has no attribute 'get_product_price'

This is the code:

sales = self.env['sale.order'].search(domain)

# Convert sales variable to a list of dictionaries
sales_list = []
for sale in sales:
    sale_dict = {
        'id': sale.id,
        'name': sale.name,
        'list': sale.pricelist_id,
        'order_line': []
    }
    for line in sale["order_line"]:
        line_dict = {
            'id': line.id,
            'product_id': line.product_id.id,
            'product_name': line.product_id.name,
            'original_number': line.product_id.original_number,
            'price_list': sale.pricelist_id.get_product_price(line.product_id)

        }
