Jira Create Issue using python

Question

I'm trying to create a Jira Issue with python, but while calling the new issue method getting below error, seems i'm missing something or not trying the right way, the fields of report frequency, report request type & due date is mandatory fields. Can anyone help me with the error?

jira.exceptions.JIRAError: JiraError HTTP 400 url: https://neomediaworld.atlassian.net/rest/api/2/issue
    text: Field 'report frequency' cannot be set. It is not on the appropriate screen, or unknown., Field 'report request type' cannot be set. It is not on the appropriate screen, or unknown., Field 'due date' cannot be set. It is not on the appropriate screen, or unknown., Field 'market' cannot be set. It is not on the appropriate screen, or unknown.

The code is as below.
