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 out-of-zone address flow from checkout and locate where the "Result not defined" message is produced. Trace the place-order screen's error handling and address navigation; done means the specified delivery-area popup appears and the user can return to checkout after correcting the address.
