  As noted by the title, I want to get job rest api to get the job's xml description.
  
  Below is my code:

               HttpWebRequest request = HttpWebRequest.Create(HpcBaseAddress + "/Job/25?Render=HpcJobXml") as HttpWebRequest;
              //HttpWebRequest request = HttpWebRequest.Create(HpcBaseAddress + "/Job/25?Render=RestPropRender") as HttpWebRequest;
              request.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
              ICredentials credsBasic = new NetworkCredential(credUserName, credPassword);
  
              request.Credentials = credsBasic;
              
  
              request.ContentType = "application/xml; charset=utf-8";
              // here we add the required version header
              request.Headers["api-version"] = "2012-11-01.4.0";
  
              request.Method = "GET";
  
              HttpWebResponse response = request.GetResponse() as HttpWebResponse;
              Stream respStream = response.GetResponseStream();
  
              string retString;
              using (StreamReader reader = new StreamReader(respStream))
              {
                  retString = reader.ReadToEnd();
  
                  reader.Close();
                  respStream.Close();
              }
  
              Console.WriteLine($"retString = {retString}");
              response.GetResponseStream().Close();
              response.Close();

  
  

  In line

  HttpWebRequest request = HttpWebRequest.Create(HpcBaseAddress + "/Job/25?Render=HpcJobXml") as HttpWebRequest;

  
  

  I'm using Render=HpcJobXml to get the job's xml description.

  But I got below errors:

  HTTP/1.1 400 The request could not be understood by the server
  Content-Type: application/xml; charset=utf-8

      <Message>The value of the render parameter HpcJobXml is invalid. You can specify a value of HpcJobXml to render the output in the format of an HPC job xml file instead of as the default web xml.</Message>
      <Values i:nil="true" xmlns:a="http://schemas.datacontract.org/2004/07/System.Collections.Generic"/>
  </HpcWebServiceFault>

  
  

  You can see that the exception message is very strange. 

  But if i using below line:

  HttpWebRequest request = HttpWebRequest.Create(HpcBaseAddress + "/Job/25?Render=RestPropRender") as HttpWebRequest;

  It returns correct response.

  So, If it is a bug? 

  And is so, are there other ways to get the job's xml description using REST API?
