title: Jira Python Custom Fields
body: <p>I am writing a script to create bugs. We have many custom fields and I cannot figure out how to get them to work correctly in the python code. Can someone please help explain? I have read through as many articles as I can find but none of the solutions are working.</p>
  
  <p>One example of my custom field names is customfield_15400 and has a default value of "NO". The error I get with my below code is:</p>
  
  <pre><code>response text = {"errorMessages":[],"errors":{"customfield_15400":"Could not find valid 'id' or 'value' in the Parent Option object."}}
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>    project_dict = {'Aroid':'SA', 'OS':'SC'}
      epic_dict = {'Aroid':'SA-108', 'OS':'SC-3333'}
  
      for index, row in bugs.iterrows():
          issue = st_jira.create_issue(project= project_dict[row['OS']], \
                              summary= "[UO] QA Issue with '%s' on '%s'" % (row['Event Action'], row['Screen Name']), \
                              issuetype= {'name':'Bug'},\
                              customfield_15400="No"
                              )
  </code></pre>
