Perform multiple simultaneous ajax calls and zip the results is not working

[augusto-altman]

I'm trying to perform multiple simultaneous ajax request to a REST api and get a stream that emits a value with a data structure containing the data retrieved by all the responses altogether. For this I'm using zip but I'm getting the following exception from Bacon.js:
Uncaught Error: At least one EventStream required

As an example, below there is a simplified version of my code:

let profileStreams = [];
let profiles = {
  someURL: {
    href: 'www.google.com'
  },
  someOtherURL: {
    href: 'github.com'
  },
  yetAnotherURL: {
    href: 'twitter.com'
  }
};

for (let index in profiles) {
  profileStreams.push(
    b$.ajax({
      url: profiles[index].href
    }).map((profileObject) => {
      return {
        owner: index,
        profile: profileObject
      };
    })
  );
}

let allUrlsRetrievedAsArray = Bacon.zipAsArray(profileStreams);

Use combineAsArray instead.

Using combineAsArray I didn't get the exception. The problem now is that whenever I get a value in the combined stream that value is an Array of EventStreams instead the an Array with the requests' responses. On the other hand when I use Bacon.fromPromise with my ajax requests instead of Bacon.$.ajax it works nice both with combine and with zip. So my guess here is that Bacon.$.ajax is doing some transformation behind the scene.

for (let index in profiles) {
    profileStreams.push(
      Bacon.fromPromise($.ajax({
        url: profiles[index].href
      })).map((profileObject) => {
        return {
          owner: index,
          profile: profileObject
        };
      })
    );
  }
