Fine Uploader с Coldfusion

Я получаю внутреннюю ошибку сервера 500 при попытке использовать http://fineuploader.com/ на стороне сервера Coldfusion https://github.com/Widen/fine-uploader-server/tree/master/coldfusion

Консоль сообщает:
[FineUploader] Ошибка при попытке проанализировать текст ответа xhr (SyntaxError: Unexpected token ‹) в этой строке в window.console.log('‹' + level + '> ' + message);

Кажется, это исходит из ответного сообщения в CFC сервера.

<!--- Code provided by Pegasus Web Productions LLC - www.pegweb.com --->
<!--- get stuck use the forums http://github.com/Widen/fine-uploader --->
<!--- Tested with Adobe CF Enterprise 9.x and Fine Uploader --->
<CFCOMPONENT HINT="I do your uploads from Fine Uploader" >
<!--- function for single file submission uploads where XHR is not supported ex:->
<CFFUNCTION NAME="Upload" ACCESS="remote" OUTPUT="false" RETURNTYPE="any"     RETURNFORMAT="JSON" >
    <CFARGUMENT NAME="qqfile" TYPE="string" REQUIRED="true" />

    <CFSET var local = structNew() >
    <CFSET local.response = structNew() >
    <CFSET local.requestData = GetHttpRequestData() ><!--- get the request headers   and body --->
    <CFSET UploadDir = "/Test/file2" ><!--- set your upload directory here ex: c:\website\www\images\ --->
    <!--- check if XHR data exists --->
    <CFIF len(local.requestData.content) GT 0 >

        <CFSET local.response = UploadFileXhr(arguments.qqfile, local.requestData.content) >

        <CFELSE><!--- no XHR data so process this as standard form submission --->
            <!--- upload the file --->
            <CFFILE ACTION="upload" FILEFIELD="form.qqfile" DESTINATION="#UploadDir#" NAMECONFLICT="makeunique" >

            <!--- populate our structure with information about the image we just uploaded in case we want to use this later for CFIMAGE tags or any other processing --->
            <CFSET local.metaData = { clientFile=FILE.clientFile, clientFileExt=FILE.clientFileExt, clientFileName=FILE.clientFileName, contentSubType=FILE.contentSubType, contentType=FILE.contentType, fileSize=FILE.fileSize } />
            <!--- return the response --->
            <CFSET local.response['success'] = true >
            <CFSET local.response['type'] = 'form' >
    </CFIF>
    <CFRETURN local.response >
</CFFUNCTION>

<!--- function for browsers that support XHR ex: Almost anything but IE --->

<CFFUNCTION NAME="UploadFileXhr" ACCESS="private" OUTPUT="false" RETURNTYPE="struct" >

    <CFSET UploadDir = "" ><!--- set your upload directory here ex: c:\website\www\images\ --->
    <!--- write the contents of the http request to a file. The filename is passed with the qqfile variable --->
