KeyError: 'endDate'

this only happens when: jira.import_sprints_as_tags = True

relevant jql: jira.query = assignee = bob and (sprint in openSprints() OR sprint in futureSprints()) ORDER BY updated

my tempfix in jira.py:

       def get_due(self):
           # If the duedate is explicitly set on the issue, then use that.
           if self.record['fields'].get('duedate'):
               return self.parse_date(self.record['fields']['duedate'])
           # Otherwise, if the issue is in a sprint, use the end date of that sprint.
         sprints = self.__get_sprints()
           for sprint in filter(lambda e: e.get('state', '').lower() != 'closed', sprints):
               if 'endDate' in sprint :
                   endDate = sprint['endDate']
                   if endDate != '<null>' :
                       return self.parse_date(endDate)
