Question

What I want to do

I want to subscribe to push notifications notifying me when I make changes to items in Podio.

What I have done to achieve this

I am using the Podio JS library and have read the documentation and gone through the detailed example. I have in accordance with the instructions:

successfully authenticated with the PODIO api; and
successfully made a podio.request call (receiving responseBody with push property)

The next step in my code is as follows:

var subscribe = getItem.then (function (responseBody){ 
    return podio.push(responseBody.push).subscribe(callback);
});

var notification = subscribe.then (function () { // never gets here!
    console.log ('subscribed');
});

What is not working

The code never gets to the notification part and consequently does not execute console.log ('subscribed'). The callback I pass to podio.push(responseBody.push).subscribe(callback) never gets invoked even though I make changes to the relevant item in my Podio account.

When I run console.log(subscribe) at an interval of 1000 ms the output is and stays:

lib$es6$promise$promise$$Promise {
  _id: 2,
  _state: undefined,
  _result: undefined,
  _subscribers: 
   [ lib$es6$promise$promise$$Promise {
       _id: 3,
       _state: undefined,
       _result: undefined,
       _subscribers: [] },
     [Function],
     undefined ],
  _onerror: null }

What my question is

I would very much appreciate help identifying why the push service is not working even though I - as I see it - as done exactly as instructed by the documentation.

Thank you in advance!

请升级到podio-js的最新版本，您应该好好去。
