Error with meteor.com deployed app

The app works fine in my local environment. I’m using the ikoptiev:linkedin-extractor package and I suspect it is causing the problem.
I get these errors:

Any ideas?

I would check what is blocking this

Exception while invoking method 'contact_persons_search
 Error: Unsuccessful HTTP response

Sorry - but how can I check that?

Something like fulltext search in your project where you are using ‘contact_persons_search’ and how it is sanitized against for example “undefined” input to _.each

I only call it from one location and I’m 99% sure the input is always correct.
Also - it always works well on localhost with no problems at all.
The error seems to be in this function:

parallelAsyncExtractLinkedIn: function (urls, message) {
    var futures = _.map(urls, function (url) {
        var future = new Future();
        var onComplete = future.resolver();

        /// Make async http call
        LinkedInExtractor.getFromUrl( url, function (error, result) {
            var stuff = {link: url, result: result};
            onComplete(error, stuff);
        });

        return future;
    });

    // wait for all futures to finish
    Future.wait(futures);

    // and grab the results out.
    return _.invoke(futures, 'get');
},

In fact, the error message points to the last line (return _.invoke(futures, ‘get’)…
Any ideas?
