inconsistent result returning back from datastore.get (promise vs callback)

[taoalpha]

datastore.get with callback will return the entity, while promise format will return the array of entities...

[taoalpha]

promise:

ds.get(ds.key(["Account", args.id])).then(console.log).catch(console.log)
Promise { pending }
[ { settings: '{}',
    created: 2017-04-24T21:26:54.427Z,
  }]

vs callback:

ds.get(ds.key(["Account", args.id]), (err, entity) => console.log("===>", err, entity))
undefined
===> null { settings: '{}',
  created: 2017-04-24T21:26:54.427Z}
