TypeError: __init__() missing 1 required argument: 'id_name' - python-3.x

Question

I am making my first python project which is a grocery store e-commerce page, and Im trying to add a cart section that allows the customer to buy the product, however, whenever I run my code and go to the cart section, I get the error "TypeError: init() missing 1 required argument: 'id_name' at Cart, line 26 called from Base, line 110"
Here is my code:
class Cart(CartTemplate):
def __init__(self, items, **properties):
# Set Form properties and Data Bindings.
self.init_components(**properties)
self.order = []
self.items_1 = items
self.items_2 = items
self.items_3 = items
if not self.items_1:
self.empty_cart_panel.visible = True
self.column_panel_1.visible = False
self.repeating_panel_1.items = self.items_1
self.repeating_panel_2.items = self.items_2
self.repeating_panel_3.items = self.items_3
self.subtotal_1 = sum(dairy['price'] * item['quantity'] for item in self.items_1)
self.subtotal_2 = sum(fruit['price'] * item['quantity'] for item in self.items_2)
self.subtotal_3 = sum(vegetable['price'] * item['quantity'] for item in self.items_3)
self.subtotal = self.subtotal_1 + self.subtotal_2 + self.subtotal_3
self.subtotal_label.text = f"AED {self.subtotal:.02f}"
if self.subtotal >= 40: #free shipping for orders over AED 40
self.shipping_label.text = 'FREE'
else: #add $5 shipping
self.shipping_label.text = "$5.00"
self.subtotal = self.subtotal + 5
self.total_label.text = f"${self.subtotal:.02f}"
