[jira] [Updated] (AIRFLOW-2415) Airflow Operators are unable to
support integers in templatized fields
[ https://issues.apache.org/jira/browse/AIRFLOW-2415?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Max Payton updated AIRFLOW-2415:
--------------------------------
Description:
Currently, if you have an operator with a template fields argument that is a dictionary, e.g.:
{{template_fields = ([dict_args])}}
And you populate that dictionary with a field that an integer in a DAG, e.g.:
{{...}}
dict_args = \{'ds': '{{ ds }}', num_times: 5}
...
Then airflow will give you the following error:
{{{base_task_runner.py:95}}}{{INFO - Subtask: airflow.exceptions.AirflowException: Type '<type 'int'>' used for parameter 'dict_args[num_times]' is not supported for templating}}
