UnhandledPromiseRejectionWarning Error

Hi @bvkimball

It seems like Taurus doesn't work with promises correctly:

Issue 1: If I try to query for none existing candidate I would expect to handle the error in my subscription, however, the Taurus is throwing the error and it doesn't pass the error to subscription.

let record: Entity<Candidate> = new Entity(EntityTypes.Candidate).fields('id', 'name');
// use none existing canditate id
record.get(100);
record.subscribe((response) => {
    console.log(record.data);
}, (error) => console.error('should print the error', error));

Error message:

Issue 2: In my application I prefer to use Promises and not observables and as the observable has toPromise() the below code should work, however it seems like promise is lost somewehere as console.log or console.error are not executed.

let record: Entity<Candidate> = new Entity(EntityTypes.Candidate).fields('id', 'name');
record.get(100);
try {
  await record.toPromise();
  console.log('print me');
} catch (error) {
   console.error('print error', error);
}
