Ash Berlin-Taylor commented on AIRFLOW-4490:
--------------------------------------------
Jira is pretty forgiving about nulls I think. Can you do this as
{{ dag_run.conf.value | default(ts }}
> dag_run.conf should be an empty dictionary by default

> Key: AIRFLOW-4490
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4490
> Project: Apache Airflow
> Issue Type: Improvement
> Components: DagRun
> Reporter: Omer Yampel
> Assignee: Omer Yampel
> Priority: Trivial
>
> Currently, if no conf is provided when running a dag, the `dag_run.conf`
> instance is None.
> When a DAG might not always be triggered with a configuration, this leads to
> needing to handle an "empty" configuration like this :
> {code}
> {{ if dag_run.conf and dag_run.conf.get('value') and ... }}
> {code}
> If dag_run.conf was an empty dictionary by default, this could simply become:
> {code}
> {{ if dag_run.conf.get('key') and ....}}
> {code}
>
