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 by reproducing the checkout flow: select a delivery zone, place an order, then enter an address outside that zone. Locate the code handling the "Result not defined" error and the place-order screen; done means the requested message appears, the address can be corrected, and the user returns to checkout.
