Subject [jira] [Updated] (AIRFLOW-3415) Imports become null when triggering dagruns in a loop
Date Thu, 29 Nov 2018 02:57:00 GMT

     [ https://issues.apache.org/jira/browse/AIRFLOW-3415?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yuri Bendana updated AIRFLOW-3415:
----------------------------------
    Description: 
When triggering dagruns in a loop, the imported references become null on the second iteration. 
Here is an example [gist|[https://gist.github.com/ybendana/3bc0791fe00b099be04aca47a8d524c9].] For
the purposes here, you can ignore the DagRunSensor task. On the first iteration the 'sleeper'
dag gets triggered but on the second iteration I see a
{noformat}
TypeError: 'NoneType' object is not callable{noformat}
To workaround this, I have to copy the import (in this case trigger_dag) inside the loop.
