Form ajax upload to s3

Hi!, So I have a form that was using ajax to post the data to the server, then I add it a img file and the process was taking to long so now I want to do direct upload to s3.

I setup the :

• aws
• cors
• form
• ajax
• presigned_post

Im getting this error Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin'. I think that my persigned data its not passing correct on the ajax.
