docs: def create_issue(self, fields=None, prefetch=True, **fieldargs):
          """Create a new issue and return an issue Resource for it.
  
          Each keyword argument (other than the predefined ones) is treated as a field name and the argument's value
          is treated as the intended value for that field -- if the fields argument is used, all other keyword arguments
          will be ignored.
  
          By default, the client will immediately reload the issue Resource created by this method in order to return
          a complete Issue object to the caller; this behavior can be controlled through the 'prefetch' argument.
  
          JIRA projects may contain many different issue types. Some issue screens have different requirements for
          fields in a new issue. This information is available through the 'createmeta' method. Further examples are
          available here: https://developer.atlassian.com/display/JIRADEV/JIRA+REST+API+Example+-+Create+Issue
