Detailed explanation of the problem

I setup fineuploader s3. It's working very fine but the problem is certain 'jpeg' image files cannot be uploaded.

These are the steps taken by me so far:-

  1. I modified the filenames, extensions etc. it did not work
  2. When I disabled chunking it works fine. I mean I can upload those image files which I couldn't earlier. 3, When I open the image in MS Paint and then re-save it, it just works fine
  3. I checked the request being sent to signature generation server and found that the request data is different for those certain files that I cannot upload. Here's the dump for the data.

array:2 [ "headers" => """ AWS4-HMAC-SHA256\n 20181008T050528Z\n 20181008/ap-south-1/s3/aws4_request\n POST\n /614248b2-bc07-436f-a6c2-9105da0a7907.JPG\n uploads=\n host:someuser.s3.amazonaws.com/\n x-amz-acl:private\n x-amz-content-sha256:e3b0c44298fc1c149afce4c8998fb92427ae41e4649b934ca495991b7852b855\n x-amz-date:20181008T050528Z\n x-amz-meta-qqfilename:_DSC2300.JPG\n \n host;x-amz-acl;x-amz-content-sha256;x-amz-date;x-amz-meta-qqfilename\n e3c0c44298fc1c149afbf4c8996fb02427ab41e4649b934ca495991b7852b855 """ "v4" => "true" ] How does fineuploader decides when to send headers or when to send json request for signature?
