How to parse object during asynchronously processing function?

Question

What should I do in case when I want to call seqEach on two_objects:

Seq()
    .seq(function() {
      pivotal.getProjects(this);
    })
    .flatten()
    .seqEach(function(data) {
      var project_ids = data.project.map(function(x) { return parseInt(x.id); })
      console.log('project_ids: '.red + project_ids );
      // pivotal.getStories(project.id, { filter: "state:finished" }, this);
    })
    .seq(function() {
        var aggregatedStories = [];
        Hash.map(this.args, (function(arg) {
            aggregatedStories.push(arg[0]);
        }));
        res.send(aggregatedStories);
    });

Logs:

project_ids: 644511,340755

pivotal.getProjects(this);

returns something like

{"project": { "id": 644511}, { "id": 340755} }

So problem is because data should be replaced by data.project but how to do it?

Either you add the line data = data.project; on top of your seqEach callback, or you inject a mapping function like

.map(function(d) { return d.project; })

into your chain. Or you just change the pivotal.getProjects method…
