Answer 1

Add headers:{content-type: undefined} browser will generate a boundary for you that is for uploading a file part-and-part with streaming if you are adding 'multiple/form-data' it means you should create streaming and upload your file part-and-part

So it is okay to add request.headers = {content-type: undefined}
