Multipart File Upload Request Using Unirest in Java

Question

I am able to post this request using a REST client (Insomnia). However, when I unable to write a proper code to do the same in Java. Below is how my insomnia request looks like.

Below is how the code generated by the Client looks like.

HttpResponse response = Unirest.post("http://172.16.6.15:5053/image-service/services/image-panel-service/panel/images?=")
  .header("com.yatra.tenant.header.tenantid", "1051")
  .header("content-type", "multipart/form-data; boundary=---011000010111000001101001")
  .body("-----011000010111000001101001
Content-Disposition: form-data; name="imageFile"

")
  .asString();

Below is the code I have written in Java which doesn't work.

try {
            HttpResponse response = Unirest.post("http://172.16.6.15:5053/image-service/services/image-panel-service/panel/images")
            .header("com.yatra.tenant.header.tenantid", "1051")
            .header("content-type", "multipart/form-data")
            .field("imageFile", new File("Desert.jpg"))
            .field("imageData", new File("ImageUploadRequest.json")).asString();

            System.out.println(response.getBody());

        } catch (UnirestException e) {
            e.printStackTrace();
        }
