How to upload a word document on box using rest API

I want to upload a word document on Box( External Storage) using Rest API calls .

Since i need blob as a valid UTF -8 string I am encoding first in base 64 using Encoding util class and then decoding it back as a blob and sending request using req.setbodyasblob() ,

I have used all the required parameters but I am getting below invalid request error .

{"type":"error","status":400,"code":"invalid_request_parameters","help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"Invalid input parameters in request","request_id":"10130606285252db06ef703"}

can someone help ?

        // if(!Test.isRunningTest()){
         system.debug('Body '+res.getBody());

         system.debug('-get headers---'+res.getHeader('Location'));

          body= Encodingutil.base64Decode(res.getBody());
system.debug('Body Decoded '+body);


         if(res.getHeader('Location')!=null)

          {
             return res.getHeader('Location')+'';
