Hello, I'm not sure what you mean by "upload the actual image file" ?
A flow file is made up of attributes and content, and the content is just bytes which can be anything. If you make a POST to an end-point provided by ListenHTTP or HandleHttpRequest, and you send the image in the body of the POST, then the image will be the content of the flow file. I haven't used any S3 processors so I can't explain that behavior. -Bryan On Thu, Sep 20, 2018 at 8:00 AM Rajesh Biswas <rajesh.bis...@bridgera.com> wrote: > > Hello Bryan, > We started implanting the requirement based on your suggestion, but we faced > below issues: > > 1.
