Direct upload to S3 - 204 NO CONTENT


I tried many different add-on such as or My bucket is in London so it accept only AWS4 signed upload request so I have re-written my rails backend to comply with AWS4 way to sign upload request and it seems like my ember app talk to S3 properly because my responses looks fine. But whatever I do (like rewrite the xmlhttprequest, the form fields etc…) I am constantly thorwn a 204 no content response and in my payload my file look read but not attached.

The upload form I just use to upload those pictures worked so well I am jealous ^^ Next week-end will be my 4th in a row stuck on that, so I am close to bang my head against the wall…
