title: TechTalk.JiraRestClient to create an issue in jira - C#
body: <p>I am trying to use TechTalk.JiraRestClient to create an issue in jira. Below is what I've gotten so far</p>
  
  <pre><code>        JiraClient client = new JiraClient(url, username, password);
          var txt = client.GetIssues("JPA"); //this gets all the issues for that board.
          IssueFields fields = new IssueFields();
          fields.summary = "Create a ticket via automation.";
          fields.description = "This is a test ticket. This ticket was created via automation";
          fields.timetracking.originalEstimate = "0";
          var txt2 = client.CreateIssue("JPA", "Bug", fields);
  </code></pre>
  
  <p>I am unable to create the ticket as it throws the following error:</p>
  
  <blockquote>
    <p>TechTalk.JiraRestClient.JiraClientException was unhandled
          HResult=-2146233088

  <p>InnerException:</p>

  <p>Even when I remove the timetracking field it throws the same error. I don't know how to resolve this. Any help would be great!</p>
  
  <p>Thanks -
