body: <p>i filed up a simple script to test sending issues to jira via python,</p>
  
  <pre><code>from jira import JIRA
  
  jira_options={'server': 'https://jira.baidu.com', 'verify': False}
  
  jira=JIRA(options=jira_options,basic_auth=('testuser','passw0rd'))
  
  new_issue = jira.create_issue(project={'key': 'test'}, summary='New issue from jira-python',   description='Look into this one', issuetype={'name': 'Bug'})
  </code></pre>
  
  <p>but got the error:</p>
