FineUploader responseJSON doesnt contain success i

Question

After getting the onComplete method to fire, I found that my responseJSON variable does not appear to contain the information I expected it to. Is this me screwing up somewhere(probably), or something not working quite right? FineUploader is recognizing a successful upload, so I know its getting the response, but when I log responseJSON in the onComplete, it prints "responseJSON: ". Just the file name. no braces, brackets, etc.

Client Side Code

    uploader = new $("#collaboration-fine-uploader").fineUploader
        autoUpload: false
        multiple: false
        validation: 
            allowedExtensions: ['pdf', 'doc', 'docx', 'ppt', 'pptx', 'xls', 'xlsx']
            sizeLimit: 1024*1024*1024*10 # 10MB
        text: 
            uploadButton: "<i class='icon-plus icon-white'></i> Select Files"
        request: 
            endpoint: "/files/discussions/collaborations/upload"


    uploader.on "complete", (id, fileName, responseJSON)  ->
        console.log "responseJSON: "+responseJSON
        if (responseJSON.success)
            discussionId = responseJSON.discussionId
            $.ajax
                type: "GET"
                url: "/courses/"+serverData.course._id+"/discussions/"+discussionId
                beforeSend: (xhr) ->
                    xhr.setRequestHeader 'x-pjax', 'true'
                success: (html) ->
                    # Replace the old html
                    $(".discussions-tab").html html
                    $(".new-discussion").slideUp()
                    $("#new-discussion-modal").deactivateModal()

                    # History push
                    window.history.pushState window.history.state, "Discussions", "/courses/"+serverData.course._id+"/discussions/"+discussionId

                    # Scroll to top
                    $.scrollTo 0

Server side Response Code (just the necessary part)

response = 
    "success": true
    "discussionId": discussion.id
console.log JSON.stringify response
res.send JSON.stringify response

EDIT: I've also added a log to the FineUploader-3.3.0.js file, and it is receiving the correct JSON object, it is just not passing it back correctly for some reason.

The first parameter on the onComplete method is actually the event, so you're really referencing fileName with responseJSON. If you change your method parameters to include the event, I think that should work.

uploader.on "complete", (event, id, fileName, responseJSON)
