Hi all, I'm using the kendoUpload module on my ruby on rails application, everythings is except for the fact that kendoUpload fires an error event even if the file is correctly uploaded.

My javascript code is this:

function onError(e) {
   console.log("Error (" + e.operation + ") :: " + getFileInfo(e));
 }
 
$("#media_filename").kendoUpload({
        async: {
            saveUrl: '/admin/media/',
            removeUrl: '/admin/media/remove',
            autoUpload: true
        },
        multiple: true,
        upload: onUpload,
        success: onSuccess,
        error: onError,
        complete: onComplete
    });

the code from my controller gives me back a 200 ok http header (I see with on firebug), but (as you can se from the attach) the kendoUpload components tell's me that the file isn't uploaded but it is not true.

Any hint? Do you need more information?

I'm with the same problem. Look my screen shot attached. You can see that server answered with status 200 but kendo upload throw onError event. When I went to the server upload directory the file was there.

Hi,

The server handler should return either an empty result or JSON to signify success like described in this documentation topic. Anything else is considered as failure and the error event will be triggered.

Kind regards,

Hi 

I was running into the same problem: The server return message stated everything is fine but ran into error event on upload just because I returned something. Well it works as designed but I don't understand why KendUi (error event) in this case only reacts on the server status, independent what was sent back from server as text in whatever format. 

The main reason of my post is to make someones life easier: As the documentation says: text/plain and JSON. If you  are using PHP serverside you can do that with:

<?php
header("Content-type: text/plain");
...
echo json_encode($yourObject);
...
?>

Hello Tayger,

You are correct, returning a "text/plain" JSON is the correct way to send back data from the server to the Upload. This will trigger the success event, which is preventable:

http://docs.telerik.com/kendo-ui/api/javascript/ui/upload#events-success

This way you could still mark a file as unsuccessfully uploaded, depending on the data returned.
