Hello, 

I got this resolved, the issue was with respect to the format of flowfile being forwarded to the invokehttp proessor. in order to send post body in form type it is necessary that you convert the format of the flowfile as just file, eg , if the flowfile is "package.json" we need to convert that into just "package". from above issue i kept everything same except i just added on attribute in updateattribute processor as shown in below pic -
