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 place-order/checkout screen and trace the address and delivery-zone validation flow for the "Result not defined" error. Reproduce an order with an address outside the selected zone, then verify that the user sees the requested delivery-area message and returns to checkout after correcting the address.
