“Specified file failed upload test” error while uploading files via API

I’m trying to upload files to a localhost blog using WordPress’ API and Java. This is the code I have:

private void postMedia(){
            String token = (String)Application.getInstance().getModel().getBean(Costants.BEARER_TOKEN);
            try {
                CloseableHttpClient httpClient = HttpClients.createDefault();                
                String urlFile = "C:\\Users\\Documents\\Project\\src\\res\\test_picture.jpg";
                HttpEntity entity = MultipartEntityBuilder.create()
                        .addTextBody("title", "title")
                        .addTextBody("caption", "description")
                        .addBinaryBody("upload_file", new File(urlFile), ContentType.create("image/jpeg"), "test_picture.jpg")
                        .addTextBody("status", "publish")
                        .build();

                HttpPost httpPost = new HttpPost(Constants.URL_MEDIA);
                httpPost.setEntity(entity);
                System.out.println("Request Type: "+ httpPost.getMethod());
                httpPost.setHeader("Authorization", "Bearer " + token);
                HttpResponse response = httpClient.execute(httpPost);
                HttpEntity result = response.getEntity();
                Scanner sc = new Scanner(response.getEntity().getContent());
                System.out.println(response.getStatusLine());
                while(sc.hasNext()) {
                    System.out.println(sc.nextLine());
                }
                } catch (Exception e) {
                e.printStackTrace();
            }   

Constants.URL_MEDIA is http://localhost/tesi/wp-json/wp/v2/media

The output I get from the scanner is:

Request Type: POST
HTTP/1.1 500 Internal Server Error
{"code":"rest_upload_unknown_error","message":"Specified file failed upload test.","data":{"status":500}}

What am I missing or doing wrong?
