Jira response (class: Issue ) is not picklable

looks like Issue class is not pickable

sqlalchemy.exc.InvalidRequestError: This Session's transaction has been rolled back due to a previous exception during flush. To begin a new transaction with this Session, first issue Session.rollback(). Original exception was: (pickle.PicklingError) Can't pickle <class 'jira.resources.PropertyHolder'>: it's not found as jira.resources.PropertyHolder [SQL: u'INSERT INTO xcom (`key`, value, timestamp, execution_date, task_id, dag_id) VALUES (%s, %s, now(), %s, %s, %s)'] [parameters: [{'task_id': '<task_id>', 'execution_date': datetime.datetime(2016, 12, 13, 0, 4), 'value': [<JIRA Issue: key=u'<project>-1855', id=u'<id>'>], 'key': 'result_set', 'dag_id': '<dag_id>'}]]

I also tried this with manual json.dumps to confirm, here is the stacktrace

Traceback (most recent call last):

    raise TypeError(repr(o) + " is not JSON serializable")
TypeError: <JIRA Issue: key=u'<project>-1855', id=u'<id>'> is not JSON serializable

Do anybody know how can should I serialize any response from JIRA ?

Is there any update on this? @mdoar 's solution works for pickle.dump, but I’m not able to load the dumped data back with pickle.load.

Would be really cool if this could make it into a release soon…
