smartcar.Vehicle(vehicle_id, access_token) returns undefined after update

[RobinJayaswal]

The following code worked to return vehicle objects before the update:

return Promise.map(vehicle_ids.vehicles, function(vehicle_id) {
     var vehicle = client.getVehicle(access.access_token, vehicle_id);
     return vehicle.info();
});

I see from the README this is no longer the way to do it, and changed the code to:

console.log(vehicle_ids);
console.log(access.access_token);
return Promise.map(vehicle_ids.vehicles, function(vehicle_id) {
   var vehicle = smartcar.Vehicle(vehicle_id, access.access_token);
   console.log(vehicle)
   return vehicle.info();
});

However, vehicle is now undefined, even right after I go through the OAuth process and have a completely new access token in hand.

{ vehicles:

     'aa4cb9ab-e388-441d-937a-8f24a0bb6851' ],
  paging: { count: 3, offset: 0 } }

missing the 'new' keyword. Try:

var vehicle = new smartcar.Vehicle(vehicle_id, access.access_token);

[gurpreetatwal]

constructors should throw error if not called with new

function Vehicle(...) {
  if (!(this instanceof Vehicle)  throw Error()
}
