When the user is out of zone and on checkout screen the popup is being shown saying "Result not defined".

Is your feature request related to a problem? Please describe.
When the user selects the zone and orders the food and then adds the address and that address is out of the delivering zone then this error is being produce.

Describe the solution you'd like
When this scenario happens then at the place order screen there should be a popup saying "We don't deliver in this area. Please add your address correctly." And after adding the address again the user should be redirected to the place order/checkout screen.

Start at the checkout or place-order screen and trace the flow used when an entered address is outside the selected delivery zone. Confirm the out-of-zone case shows "We don't deliver in this area. Please add your address correctly." and returns the user to checkout after the address is corrected.
