Fiber Parent Callback

gistfile1.js

uploadS3: function (file, callback, callbackArgs) {
        var s3 = new AWS.S3();
        var options = {
            partSize: 10 * 1024 * 1024,
            queueSize: 1
        };
        s3.upload(file, options, function (error, data) {
            if (callback) {
                Meteor.wrapAsync(Meteor.call(callback, callbackArgs, {error: error, data: data})); //Barfs 
               
            }
        });
    }

Something like this:

uploadS3: function (file, callback, callbackArgs) {
        var s3 = new AWS.S3();
        var uploadSync = Meteor.wrapAsync(s3.upload);
        var options = {
            partSize: 10 * 1024 * 1024,
            queueSize: 1
        };
        uploadSync(file, options, function (error, data) {
            if (callback) {
                Meteor.call(callback, callbackArgs, {error: error, data: data}); //Barfs 
            }
        });
    }
