Creating issue via JIRA API with python gives HTTP 400 error

Question

Im new to python and trying to create simple script that will creates new issue in JIRA.

Not sure what's wrong in my code.

from jira.client import JIRA


options={'server': 'https://jira.my_jira.com'}

jira=JIRA(options,basic_auth=('user', 'pass'))


root_dict = {

'project' : { 'key': 'project_name' },

'summary' : 'Test auto created issue',

'description' : 'Ignore this. will be deleted shortly',

'issuetype' : { 'name' : 'Task' },

}

my_issue= jira.create_issue(fields=root_dict)

The error is gives

JIRAError: HTTP 400: "Account is required." https://jira.my_jira.com/rest/api/2/issue

Could someone advice what's wrong?
