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.

Reproduce the checkout flow by selecting a zone, adding an address outside the delivery area, and reaching the place-order screen. Trace the code handling the resulting "Result not defined" popup and address submission; done means the requested delivery-area message appears and the user returns to checkout after correcting the address.
