     if ($scope.object2.property88 == "a bad value")
        throw "Oh no! Something failed!";
     return $http.get('/a_third_thing/654321');
  })
  .then(function(response) {
     $scope.object3 = response.data;
  })
  .catch(function(error) {
     // this catches errors from the $http calls as well as from the explicit throw
     console.log("An error occured: " + error);
  })
  .finally(function() {
     $scope.spinner.stop();
  });
